- org.springframework.beans.factory.xml.DefaultNamespaceHandlerResolver

All Implemented Interfaces:
NamespaceHandlerResolver
```
public class DefaultNamespaceHandlerResolver
extends Object
implements NamespaceHandlerResolver
```
Default implementation of the NamespaceHandlerResolver interface. Resolves namespace URIs to implementation classes based on the mappings contained in mapping file.
By default, this implementation looks for the mapping file at META-INF/spring.handlers, but this can be changed using the DefaultNamespaceHandlerResolver(ClassLoader, String) constructor.
Since:
2.0
