SpringMVC中获取request对象的几种方式

1.最简单的方式（注解法）

@Autowired
private  HttpServletRequest request;

2.最麻烦的方法

   在web.xml中配置一个监听

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

   之后在程序里可以用

HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest(); 

3.最直接的方法

public String hello(HttpServletRequest request,HttpServletResponse response)  

Struts2中获取request对象

HttpServletRequest request = ServletActionContext.getRequest();
