Java 获取Request,Response对象方法

第一种、参数

@RequestMapping("/test")
@ResponseBody
public void saveTest(HttpServletRequest req, HttpServletResponse resp){　　
}      

第二种、注解

@Autowired  
private  HttpServletRequest request;      

第三种、上下文获取

1、在web.xml配置监听器

<listener>
      <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>      

HttpServletRequest req = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
HttpServletResponse resp = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getResponse();
