UriComponents

java.lang.Object
- org.springframework.web.util.UriComponents

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

HierarchicalUriComponents, OpaqueUriComponents
```
public abstract class UriComponents
extends java.lang.Object
implements java.io.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.

Since:

3.1
