Class UriComponents

java.lang.Object

org.springframework.web.util.UriComponents

All Implemented Interfaces:

Serializable

public abstract class UriComponents
extends Object
implements Serializable

Represents an immutable collection of URI components, mapping component type to String values. Contains convenience getters for all components. Effectively similar to URI, but with more powerful encoding options and support for URI template variables.

3.1

Method Detail

getScheme

public final String getScheme()

Return the scheme. Can be null.

getSchemeSpecificPart

public abstract String getSchemeSpecificPart()

Return the scheme specific part. Can be null.

getUserInfo

public abstract String getUserInfo()

Return the user info. Can be null.

getHost

public abstract String getHost()

Return the host. Can be null.

getPort

public abstract int getPort()

Return the port. -1 if no port has been set.

getPath

public abstract String getPath()

Return the path. Can be null.

getPathSegments

public abstract List<String> getPathSegments()

Return the list of path segments. Empty if no path has been set.

getQuery

public abstract String getQuery()

Return the query. Can be null.

getQueryParams

public abstract MultiValueMap<String,String> getQueryParams()

Return the map of query parameters. Empty if no query has been set.

getFragment

public final String getFragment()

Return the fragment. Can be null.

encode

public final UriComponents encode()

Encode all URI components using their specific encoding rules, and returns the result as a new UriComponents instance. This method uses UTF-8 to encode.

Returns:

the encoded URI components

encode

public abstract UriComponents encode(String encoding)
                              throws UnsupportedEncodingException

Encode all URI components using their specific encoding rules, and returns the result as a new UriComponents instance.

Parameters:

encoding - the encoding of the values contained in this map

Returns:

the encoded URI components

Throws:

UnsupportedEncodingException - if the given encoding is not supported

expand

public final UriComponents expand(Map<String,?> uriVariables)

Replace all URI template variables with the values from a given map.

The given map keys represent variable names; the corresponding values represent variable values. The order of variables is not significant.

Parameters:

uriVariables - the map of URI variables

Returns:

the expanded URI components

expand

public final UriComponents expand(Object... uriVariableValues)

Replace all URI template variables with the values from a given array.

The given array represents variable values. The order of variables is significant.

Parameters:

uriVariableValues - the URI variable values

Returns:

the expanded URI components

expand

public final UriComponents expand(UriComponents.UriTemplateVariables uriVariables)

Replace all URI template variables with the values from the given UriComponents.UriTemplateVariables.

Parameters:

uriVariables - the URI template values

Returns:

the expanded URI components

normalize

public abstract UriComponents normalize()

Normalize the path removing sequences like "path/..".

StringUtils.cleanPath(String)

toUriString

public abstract String toUriString()

Return a URI String from this UriComponents instance.

toUri

public abstract URI toUri()

Return a URI from this UriComponents instance.

toString

public final String toString()

Overrides:

toString in class Object

copyToUriComponentsBuilder

protected abstract void copyToUriComponentsBuilder(UriComponentsBuilder builder)

Set all components of the given UriComponentsBuilder.
