  - setCharacterEncoding
```
public void setCharacterEncoding(String characterEncoding)
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Sets the character encoding (MIME charset) of the response being sent to the client, for example, to UTF-8. If the response character encoding has already been set by the ServletContext.setResponseCharacterEncoding(java.lang.String), deployment descriptor, or using the setContentType() or setLocale() methods, the value set in this method overrides any of those values. Calling ServletResponse.setContentType(java.lang.String) with the String of text/html and calling this method with the String of UTF-8 is equivalent with calling setContentType with the String of text/html; charset=UTF-8.
    This method can be called repeatedly to change the character encoding. This method has no effect if it is called after getWriter has been called or after the response has been committed.
    Containers must communicate the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the character encoding is communicated as part of the Content-Type header for text media types. Note that the character encoding cannot be communicated via HTTP headers if the servlet does not specify a content type; however, it is still used to encode text written via the servlet response's writer.
    
    Specified by:
    
    setCharacterEncoding in interface ServletResponse
    
    Parameters:
    
    characterEncoding - a String specifying only the character set defined by IANA Character Sets (http://www.iana.org/assignments/character-sets)
    
    See Also:
    
    ServletResponse.setContentType(java.lang.String), ServletResponse.setLocale(java.util.Locale)
  - getCharacterEncoding
```
@Nullable
public String getCharacterEncoding()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns the name of the character encoding (MIME charset) used for the body sent in this response. The following methods for specifying the response character encoding are consulted, in decreasing order of priority: per request, perweb-app (using ServletContext.setResponseCharacterEncoding(java.lang.String), deployment descriptor), and per container (for all web applications deployed in that container, using vendor specific configuration). The first one of these methods that yields a result is returned. Per-request, the charset for the response can be specified explicitly using the setCharacterEncoding and setContentType methods, or implicitly using the setLocale(java.util.Locale) method. Explicit specifications take precedence over implicit specifications. Calls made to these methods after getWriter has been called or after the response has been committed have no effect on the character encoding. If no character encoding has been specified, ISO-8859-1 is returned.
    See RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt) for more information about character encoding and MIME.
    
    Specified by:
    
    getCharacterEncoding in interface ServletResponse
    
    Returns:
    
    a String specifying the name of the character encoding, for example, UTF-8
  - getOutputStream
```
public ServletOutputStream getOutputStream()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data.
    Calling flush() on the ServletOutputStream commits the response. Either this method or ServletResponse.getWriter() may be called to write the body, not both, except when ServletResponse.reset() has been called.
    
    Specified by:
    
    getOutputStream in interface ServletResponse
    
    Returns:
    
    a ServletOutputStream for writing binary data
    
    See Also:
    
    ServletResponse.getWriter(), ServletResponse.reset()
  - getWriter
```
public PrintWriter getWriter()
                      throws UnsupportedEncodingException
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns a PrintWriter object that can send character text to the client. The PrintWriter uses the character encoding returned by ServletResponse.getCharacterEncoding(). If the response's character encoding has not been specified as described in getCharacterEncoding (i.e., the method just returns the default value ISO-8859-1), getWriter updates it to ISO-8859-1.
    Calling flush() on the PrintWriter commits the response.
    Either this method or ServletResponse.getOutputStream() may be called to write the body, not both, except when ServletResponse.reset() has been called.
    
    Specified by:
    
    getWriter in interface ServletResponse
    
    Returns:
    
    a PrintWriter object that can return character data to the client
    
    Throws:
    
    UnsupportedEncodingException - if the character encoding returned by getCharacterEncoding cannot be used

```
  - getContentAsString
```
public String getContentAsString()
                          throws UnsupportedEncodingException
```
    Get the content of the response body as a String, using the charset specified for the response by the application, either through HttpServletResponse methods or through a charset parameter on the Content-Type.
    
    Returns:
    
    the content as a String
    
    Throws:
    
    UnsupportedEncodingException - if the character encoding is not supported

```
    Get the content of the response body as a String, using the provided fallbackCharset if no charset has been explicitly defined and otherwise using the charset specified for the response by the application, either through HttpServletResponse methods or through a charset parameter on the Content-Type.
    
    Returns:
    
    the content as a String
    
    Throws:

    Specified by:
    
    setContentLengthLong in interface ServletResponse
    
    Parameters:
    
    contentLength - a long specifying the length of the content being returned to the client; sets the Content-Length header

public long getContentLengthLong()
```
  - setContentType
```
public void setContentType(@Nullable
                           String contentType)
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.
    This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed. It does not set the response's character encoding if it is called after getWriter has been called or after the response has been committed.
    Containers must communicate the content type and the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the Content-Type header is used.
    
    Specified by:
    
    setContentType in interface ServletResponse
    
    Parameters:
    
    contentType - a String specifying the MIME type of the content
    
    See Also:
    
    ServletResponse.setLocale(java.util.Locale), ServletResponse.setCharacterEncoding(java.lang.String), ServletResponse.getOutputStream(), ServletResponse.getWriter()
  - getContentType
```
@Nullable
public String getContentType()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns the content type used for the MIME body sent in this response. The content type proper must have been specified using ServletResponse.setContentType(java.lang.String) before the response is committed. If no content type has been specified, this method returns null. If a content type has been specified, and a character encoding has been explicitly or implicitly specified as described in ServletResponse.getCharacterEncoding() or ServletResponse.getWriter() has been called, the charset parameter is included in the string returned. If no character encoding has been specified, the charset parameter is omitted.
    
    Specified by:
    
    getContentType in interface ServletResponse
    
    Returns:
    
    a String specifying the content type, for example, text/html; charset=UTF-8, or null
  - setBufferSize
```
public void setBufferSize(int bufferSize)
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Sets the preferred buffer size for the body of the response. The servlet container will use a buffer at least as large as the size requested. The actual buffer size used can be found using getBufferSize.
    A larger buffer allows more content to be written before anything is actually sent, thus providing the servlet with more time to set appropriate status codes and headers. A smaller buffer decreases server memory load and allows the client to start receiving data more quickly.
    This method must be called before any response body content is written; if content has been written or the response object has been committed, this method throws an IllegalStateException.
    
    Specified by:
    
    setBufferSize in interface ServletResponse
    
    Parameters:
    
    bufferSize - the preferred buffer size
    
    See Also:
    
    ServletResponse.getBufferSize(), ServletResponse.flushBuffer(), ServletResponse.isCommitted(), ServletResponse.reset()
  - getBufferSize
```
public int getBufferSize()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns the actual buffer size used for the response. If no buffering is used, this method returns 0.
    
    Specified by:
    
    getBufferSize in interface ServletResponse
    
    Returns:
    
    the actual buffer size used
    
    See Also:
    
    ServletResponse.setBufferSize(int), ServletResponse.flushBuffer(), ServletResponse.isCommitted(), ServletResponse.reset()
  - flushBuffer
```
public void flushBuffer()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Forces any content in the buffer to be written to the client. A call to this method automatically commits the response, meaning the status code and headers will be written.
    
    Specified by:
    
    flushBuffer in interface ServletResponse
    
    See Also:
    
    ServletResponse.setBufferSize(int), ServletResponse.getBufferSize(), ServletResponse.isCommitted(), ServletResponse.reset()
  - resetBuffer
```
public void resetBuffer()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Clears the content of the underlying buffer in the response without clearing headers or status code. If the response has been committed, this method throws an IllegalStateException.
    
    Specified by:
    
    resetBuffer in interface ServletResponse
    
    See Also:
    
    ServletResponse.setBufferSize(int), ServletResponse.getBufferSize(), ServletResponse.isCommitted(), ServletResponse.reset()
  - setCommitted
```
public void setCommitted(boolean committed)
```
  - isCommitted
```
public boolean isCommitted()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns a boolean indicating if the response has been committed. A committed response has already had its status code and headers written.
    
    Specified by:
    
    isCommitted in interface ServletResponse
    
    Returns:
    
    a boolean indicating if the response has been committed
    
    See Also:
    
    ServletResponse.setBufferSize(int), ServletResponse.getBufferSize(), ServletResponse.flushBuffer(), ServletResponse.reset()
  - reset
```
public void reset()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Clears any data that exists in the buffer as well as the status code, headers. The state of calling ServletResponse.getWriter() or ServletResponse.getOutputStream() is also cleared. It is legal, for instance, to call ServletResponse.getWriter(), ServletResponse.reset() and then ServletResponse.getOutputStream(). If ServletResponse.getWriter() or ServletResponse.getOutputStream() have been called before this method, then the corrresponding returned Writer or OutputStream will be staled and the behavior of using the stale object is undefined. If the response has been committed, this method throws an IllegalStateException.
    
    Specified by:
    
    reset in interface ServletResponse
    
    See Also:
    
    ServletResponse.setBufferSize(int), ServletResponse.getBufferSize(), ServletResponse.flushBuffer(), ServletResponse.isCommitted()
  - setLocale
```
public void setLocale(Locale locale)
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Sets the locale of the response, if the response has not been committed yet. It also sets the response's character encoding appropriately for the locale, if the character encoding has not been explicitly set using ServletResponse.setContentType(java.lang.String) or ServletResponse.setCharacterEncoding(java.lang.String), getWriter hasn't been called yet, and the response hasn't been committed yet. If the deployment descriptor contains a locale-encoding-mapping-list element, and that element provides a mapping for the given locale, that mapping is used. Otherwise, the mapping from locale to character encoding is container dependent.
    This method may be called repeatedly to change locale and character encoding. The method has no effect if called after the response has been committed. It does not set the response's character encoding if it is called after ServletResponse.setContentType(java.lang.String) has been called with a charset specification, after ServletResponse.setCharacterEncoding(java.lang.String) has been called, after getWriter has been called, or after the response has been committed.
    Containers must communicate the locale and the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the locale is communicated via the Content-Language header, the character encoding as part of the Content-Type header for text media types. Note that the character encoding cannot be communicated via HTTP headers if the servlet does not specify a content type; however, it is still used to encode text written via the servlet response's writer.
    
    Specified by:
    
    setLocale in interface ServletResponse
    
    Parameters:
    
    locale - the locale of the response

```
public Locale getLocale()
```
    Description copied from interface: javax.servlet.ServletResponse
    
    Returns the locale specified for this response using the ServletResponse.setLocale(java.util.Locale) method. Calls made to setLocale after the response is committed have no effect. If no locale has been specified, the container's default locale is returned.
    
    Specified by:
    
    getLocale in interface ServletResponse
    
    Returns:
    
    the Locale for this response.

    Can be overridden in subclasses, appending a session id or the like.
    
    Specified by:
    
    encodeURL in interface HttpServletResponse
    
    Parameters:
    
    url - the url to be encoded.
    
    Returns:
    
    the encoded URL if encoding is needed; the unchanged URL otherwise.
  - encodeRedirectURL
```
public String encodeRedirectURL(String url)
```
    The default implementation delegates to encodeURL(java.lang.String), returning the given URL String as-is.
    Can be overridden in subclasses, appending a session id or the like in a redirect-specific fashion. For general URL encoding rules, override the common encodeURL(java.lang.String) method instead, applying to redirect URLs as well as to general URLs.
    
    Specified by:
    
    encodeRedirectURL in interface HttpServletResponse
    
    Parameters:
    
    url - the url to be encoded.
    
    Returns:
    
    the encoded URL if encoding is needed; the unchanged URL otherwise.

```
public void sendError(int status,
                      String errorMessage)
               throws IOException
```
    Description copied from interface: javax.servlet.http.HttpServletResponse
    
    Sends an error response to the client using the specified status and clears the buffer. The server defaults to creating the response to look like an HTML-formatted server error page containing the specified message, setting the content type to "text/html". The caller is not responsible for escaping or re-encoding the message to ensure it is safe with respect to the current response encoding and content type. This aspect of safety is the responsibility of the container, as it is generating the error page containing the message. The server will preserve cookies and may clear or update any headers needed to serve the error page as a valid response.
    
    If an error-page declaration has been made for the web application corresponding to the status code passed in, it will be served back in preference to the suggested msg parameter and the msg parameter will be ignored.
    
    If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.
    
    Specified by:
    
    sendError in interface HttpServletResponse
    
    Parameters:
    
    status - the error status code
    
    errorMessage - the descriptive message
    
    Throws:
    
    IOException - If an input or output exception occurs
  - sendError
```
public void sendError(int status)
               throws IOException
```
    Description copied from interface: javax.servlet.http.HttpServletResponse
    
    Sends an error response to the client using the specified status code and clears the buffer. The server will preserve cookies and may clear or update any headers needed to serve the error page as a valid response. If an error-page declaration has been made for the web application corresponding to the status code passed in, it will be served back the error page
    If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.
    
    Specified by:
    
    sendError in interface HttpServletResponse
    
    Parameters:
    
    status - the error status code
    
    Throws:
    
    IOException - If an input or output exception occurs
  - sendRedirect
```
public void sendRedirect(String url)
                  throws IOException
```
    Description copied from interface: javax.servlet.http.HttpServletResponse
    
    Sends a temporary redirect response to the client using the specified redirect location URL and clears the buffer. The buffer will be replaced with the data set by this method. Calling this method sets the status code to HttpServletResponse.SC_FOUND 302 (Found). This method can accept relative URLs;the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI. If the location is relative with a leading '/' the container interprets it as relative to the servlet container root. If the location is relative with two leading '/' the container interprets it as a network-path reference (see RFC 3986: Uniform Resource Identifier (URI): Generic Syntax, section 4.2 "Relative Reference").
    If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.
    
    Specified by:
    
    sendRedirect in interface HttpServletResponse
    
    Parameters:
    
    url - the redirect location URL

  - setStatus
```
public void setStatus(int status)
```
    Description copied from interface: javax.servlet.http.HttpServletResponse
    
    Sets the status code for this response.
    This method is used to set the return status code when there is no error (for example, for the SC_OK or SC_MOVED_TEMPORARILY status codes).
    If this method is used to set an error code, then the container's error page mechanism will not be triggered. If there is an error and the caller wishes to invoke an error page defined in the web application, then HttpServletResponse.sendError(int, java.lang.String) must be used instead.
    This method preserves any cookies and other response headers.
    Valid status codes are those in the 2XX, 3XX, 4XX, and 5XX ranges. Other status codes are treated as container specific.
    
    Specified by:
    
    setStatus in interface HttpServletResponse
    
    Parameters:
    
    status - the status code
