UriComponentsBuilder (spring-web 3.2.9.RELEASE API)

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

```
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.

```
protected UriComponentsBuilder()
```
    Default constructor. Protected to prevent direct instantiation.
    
    See Also:
    newInstance(), fromPath(String), fromUri(URI)
- 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.
    Note: The presence of reserved characters can prevent correct parsing of the URI string. For example if a query parameter contains '=' or '&' characters, the query string cannot be parsed unambiguously. Such values should be substituted for URI variables to enable correct parsing:
```
 String uriString = "/hotels/42?filter={value}";
 UriComponentsBuilder.fromUriString(uriString).buildAndExpand("hot&cold");
 
```
    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.
    Note: The presence of reserved characters can prevent correct parsing of the URI string. For example if a query parameter contains '=' or '&' characters, the query string cannot be parsed unambiguously. Such values should be substituted for URI variables to enable correct parsing:
```
 String uriString = "/hotels/42?filter={value}";
 UriComponentsBuilder.fromUriString(uriString).buildAndExpand("hot&cold");
 
```
    Parameters:
    httpUrl - the source URI

    this UriComponentsBuilder
  - replaceQueryParam
