Class UriBuilder
- java.lang.Object
-
- javax.ws.rs.core.UriBuilder
-
public abstract class UriBuilder extends java.lang.Object
URI template aware utility class for building URIs from their components. SeePath.value()
for an explanation of URI templates.Builder methods perform contextual encoding of characters not permitted in the corresponding URI component following the rules of the application/x-www-form-urlencoded media type for query parameters and RFC 3986 for all other components. Note that only characters not permitted in a particular component are subject to encoding so, e.g., a path supplied to one of the
path
methods may contain matrix parameters or multiple path segments since the separators are legal characters and will not be encoded. Percent encoded values are also recognized where allowed and will not be double encoded.URI templates are allowed in most components of a URI but their value is restricted to a particular component. E.g.
would result in encoding of the '#' such that the resulting URI is "foo%23bar". To create a URI "foo#bar" useUriBuilder.fromPath("{arg1}").build("foo#bar");
instead. URI template names and delimiters are never encoded but their values are encoded when a URI is built. Template parameter regular expressions are ignored when building a URI, i.e. no validation is performed.UriBuilder.fromPath("{arg1}").fragment("{arg2}").build("foo", "bar")
