org.springframework.beans.factory.xml.DefaultNamespaceHandlerResolver

所有已实现的接口:

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.

从以下版本开始:

2.0
