Direct Known Subclasses:

ServletUriComponentsBuilder

public class UriComponentsBuilder
extends Object

Builder for UriComponents.

Typical usage involves:

1. Create a UriComponentsBuilder with one of the static factory methods (such as fromPath(String) or fromUri(URI))
2. Set the various URI components through the respective methods (scheme(String), userInfo(String), host(String), port(int), path(String), pathSegment(String...), queryParam(String, Object...), and fragment(String).
3. Build the UriComponents instance with the build() method.

Method Detail

newInstance

public static UriComponentsBuilder newInstance()

Returns a new, empty builder.

Returns:

the new UriComponentsBuilder

fromPath

public static UriComponentsBuilder fromPath(String path)

Returns a builder that is initialized with the given path.

Parameters:

path - the path to initialize with

Returns:

the new UriComponentsBuilder

fromUri

public static UriComponentsBuilder fromUri(URI uri)

Returns a builder that is initialized with the given URI.

Parameters:

uri - the URI to initialize with

Returns:

the new UriComponentsBuilder

fromUriString

public static UriComponentsBuilder fromUriString(String uri)

Returns a builder that is initialized with the given URI string.

Parameters:

uri - the URI string to initialize with

Returns:

the new UriComponentsBuilder

fromHttpUrl

public static UriComponentsBuilder fromHttpUrl(String httpUrl)

Creates a new UriComponents object from the string HTTP URL.

Parameters:

httpUrl - the source URI

Returns:

the URI components of the URI

build

public UriComponents build()

Builds a UriComponents instance from the various components contained in this builder.

Returns:

the URI components

build

public UriComponents build(boolean encoded)

Builds a UriComponents instance from the various components contained in this builder.

Parameters:

encoded - whether all the components set in this builder are encoded (true) or not (false).

Returns:

the URI components

buildAndExpand

public UriComponents buildAndExpand(Map<String,?> uriVariables)

Builds a UriComponents instance and replaces URI template variables with the values from a map. This is a shortcut method, which combines calls to build() and then UriComponents.expand(Map).

Parameters:

uriVariables - the map of URI variables

Returns:

the URI components with expanded values

buildAndExpand

public UriComponents buildAndExpand(Object... uriVariableValues)

Builds a UriComponents instance and replaces URI template variables with the values from an array. This is a shortcut method, which combines calls to build() and then UriComponents.expand(Object...).

Parameters:

uriVariableValues - URI variable values

Returns:

the URI components with expanded values

uri

public UriComponentsBuilder uri(URI uri)

Initializes all components of this URI builder with the components of the given URI.

Parameters:

uri - the URI

Returns:

this UriComponentsBuilder

scheme

public UriComponentsBuilder scheme(String scheme)

Sets the URI scheme. The given scheme may contain URI template variables, and may also be null to clear the scheme of this builder.

Parameters:

scheme - the URI scheme

Returns:

this UriComponentsBuilder

userInfo

public UriComponentsBuilder userInfo(String userInfo)

Sets the URI user info. The given user info may contain URI template variables, and may also be null to clear the user info of this builder.

Parameters:

userInfo - the URI user info

Returns:

this UriComponentsBuilder

host

public UriComponentsBuilder host(String host)

Sets the URI host. The given host may contain URI template variables, and may also be null to clear the host of this builder.

Parameters:

host - the URI host

Returns:

this UriComponentsBuilder

port

public UriComponentsBuilder port(int port)

Sets the URI port. Passing -1 will clear the port of this builder.

Parameters:

port - the URI port

Returns:

this UriComponentsBuilder

path

public UriComponentsBuilder path(String path)

Appends the given path to the existing path of this builder. The given path may contain URI template variables.

Parameters:

path - the URI path

Returns:

this UriComponentsBuilder

replacePath

public UriComponentsBuilder replacePath(String path)

Sets the path of this builder overriding all existing path and path segment values.

Parameters:

path - the URI path; a null value results in an empty path.

Returns:

this UriComponentsBuilder

pathSegment

public UriComponentsBuilder pathSegment(String... pathSegments)
                                 throws IllegalArgumentException

Appends the given path segments to the existing path of this builder. Each given path segments may contain URI template variables.

Parameters:

pathSegments - the URI path segments

Returns:

this UriComponentsBuilder
