static String	REQUEST_ATTRIBUTE_FROM_WEBCONTEXT

Method Summary

Modifier and Type	Method and Description
Object	getObject(String scope, String key) 获取指定范围内的对象，相当于调用request、session、servletcontext的getAttribute方法
javax.servlet.http.HttpServletRequest	getRequest() 返回请求上下文关联的http请求对象
javax.servlet.http.HttpServletResponse	getResponse() 返回请求上下文中关联的http响应对象
javax.servlet.ServletContext	getServletContext() 取得servletContext对象
WebContext	getWrappedWebContext() 获取包装过的WebContext
void	init(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response, javax.servlet.ServletContext servletContext) 初始化web上下文方法
boolean	isRequestFinished() 请求是否已终止，例如请求已被重定向了，该请求将被终止，返回true。还有访问的页面已被缓存，可以直接从缓存中获取页面信息，也将返回true， 默认实现是返回false。
void	setObject(String scope, String key, Object value) 把对象设置到scope指定的范围内,相当于调用request、session、servletcontext的setAttribute方法
void	setRequest(javax.servlet.http.HttpServletRequest request) 设置请求上下文中关联的http请求对象
void	setResponse(javax.servlet.http.HttpServletResponse response) 设置请求上下文中关联的http响应对象
void	setServletContext(javax.servlet.ServletContext servletContext) 设置servletContext对象
