UriComponentsBuilder (Spring Framework 5.0.0.RELEASE API)

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

All Implemented Interfaces:

Cloneable, UriBuilder

Direct Known Subclasses:

ServletUriComponentsBuilder
```
public class UriComponentsBuilder
extends Object
implements UriBuilder, Cloneable
```
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.

    Returns:
    
    the new UriComponentsBuilder
  - fromPath
```
public static UriComponentsBuilder fromPath(String path)
```
    Create a builder that is initialized with the given path.
