如何在SpringMVC中获取request对象

 

1.注解法

 

 

Java代码  

@Autowired  

private  HttpServletRequest request;  

@Autowired

private  HttpServletRequest request;

 

 

2. 在web.xml中配置一个监听

 

<listener>     

       <listener-class>     

         org.springframework.web.context.request.RequestContextListener     

      </listener-class>     

</listener>    

<listener> 

        <listener-class> 

            org.springframework.web.context.request.RequestContextListener 

        </listener-class> 

</listener> 

 

 

在程序里可以用

Java代码  

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

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

 

 3.直接在参数中引入

Java代码  

public String hello(HttpServletRequest request,HttpServletResponse response)  

public String hello(HttpServletRequest request,HttpServletResponse response)

 

如何在Struts2中获取request对象
