1.注解法

 

 

@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>

 

之后在程序里可以用

 

 

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

 

 3.直接在参数中引入

public String hello(HttpServletRequest request,HttpServletResponse response)

 

 

 

 

如何在Struts2中获取request对象

 

HttpServletRequest request = ServletActionContext.getRequest();
