Class ServletResponseWrapper

java.lang.Object extended byjavax.servlet.ServletResponseWrapper
All Implemented Interfaces:
ServletResponse
Direct Known Subclasses:
HttpServletResponseWrapper
public class ServletResponseWrapper
extends Object
implements ServletResponse

Provides a convenient implementation of the ServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet. This class implements the Wrapper or Decorator pattern. Methods default to calling through to the wrapped response object. 提供了一种实现ServletResponse接口的便捷方式，开发人员想采用来自Servlet的响应的话， 可以对其子类化。
