Constructor Detail

ServletUriComponentsBuilder

protected ServletUriComponentsBuilder()

Default constructor. Protected to prevent direct instantiation.

See Also:

fromContextPath(HttpServletRequest), fromServletMapping(HttpServletRequest), fromRequest(HttpServletRequest), fromCurrentContextPath(), fromCurrentServletMapping(), fromCurrentRequest()

ServletUriComponentsBuilder

protected ServletUriComponentsBuilder(ServletUriComponentsBuilder other)

Create a deep copy of the given ServletUriComponentsBuilder.

Parameters:

other - the other builder to copy from

Method Detail

fromContextPath

public static ServletUriComponentsBuilder fromContextPath(HttpServletRequest request)

Prepare a builder from the host, port, scheme, and context path of the given HttpServletRequest.

fromServletMapping

public static ServletUriComponentsBuilder fromServletMapping(HttpServletRequest request)

Prepare a builder from the host, port, scheme, context path, and servlet mapping of the given HttpServletRequest.

If the servlet is mapped by name, e.g. "/main/*", the path will end with "/main". If the servlet is mapped otherwise, e.g. "/" or "*.do", the result will be the same as if calling fromContextPath(HttpServletRequest).

fromRequestUri

public static ServletUriComponentsBuilder fromRequestUri(HttpServletRequest request)

Prepare a builder from the host, port, scheme, and path (but not the query) of the HttpServletRequest.

fromRequest

public static ServletUriComponentsBuilder fromRequest(HttpServletRequest request)

Prepare a builder by copying the scheme, host, port, path, and query string of an HttpServletRequest.

initFromRequest

private static ServletUriComponentsBuilder initFromRequest(HttpServletRequest request)

Initialize a builder with a scheme, host,and port (but not path and query).

prependForwardedPrefix

private static java.lang.String prependForwardedPrefix(HttpServletRequest request,
                                                       java.lang.String path)

fromCurrentContextPath

public static ServletUriComponentsBuilder fromCurrentContextPath()

Same as fromContextPath(HttpServletRequest) except the request is obtained through RequestContextHolder.

fromCurrentServletMapping

public static ServletUriComponentsBuilder fromCurrentServletMapping()

Same as fromServletMapping(HttpServletRequest) except the request is obtained through RequestContextHolder.

fromCurrentRequestUri

public static ServletUriComponentsBuilder fromCurrentRequestUri()

Same as fromRequestUri(HttpServletRequest) except the request is obtained through RequestContextHolder.

fromCurrentRequest

public static ServletUriComponentsBuilder fromCurrentRequest()

Same as fromRequest(HttpServletRequest) except the request is obtained through RequestContextHolder.

getCurrentRequest

protected static HttpServletRequest getCurrentRequest()

Obtain current request through RequestContextHolder.

initPath

private void initPath(java.lang.String path)

removePathExtension

public java.lang.String removePathExtension()

Remove any path extension from the requestURI. This method must be invoked before any calls to UriComponentsBuilder.path(String) or UriComponentsBuilder.pathSegment(String...).

 GET http://foo.com/rest/books/6.json

 ServletUriComponentsBuilder builder = ServletUriComponentsBuilder.fromRequestUri(this.request);
 String ext = builder.removePathExtension();
 String uri = builder.path("/pages/1.{ext}").buildAndExpand(ext).toUriString();
 assertEquals("http://foo.com/rest/books/6/pages/1.json", result);
 

Returns:

the removed path extension for possible re-use, or null

Since:

4.0

cloneBuilder

public ServletUriComponentsBuilder cloneBuilder()

Description copied from class: UriComponentsBuilder

Clone this UriComponentsBuilder.

Overrides:

cloneBuilder in class UriComponentsBuilder

Returns:

the cloned UriComponentsBuilder object
