在SpringMVC中获取request对象

1.注解法

1. @Autowired
2. private  HttpServletRequest request;

2. 在web.xml中配置一个监听

1. <listener>
2. <listener-class>
3. org.springframework.web.context.request.RequestContextListener
4. </listener-class>
5. </listener>

之后在程序里可以用

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

3.直接在参数中引入

1. public String hello(HttpServletRequest request,HttpServletResponse response)

如何在Struts2中获取request对象

1. HttpServletRequest request = ServletActionContext.getRequest();
