Spring 获取request对象

在我们的web编程中我们常常要用到request对象,如何获取它呢.下面有几个不同的方法来实现：

1、注解法

@Autowired
private  HttpServletRequest request;

2、Spring中的RequestContextHolder

1）在web.xml中配置一个监听

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

2)程序中调用

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

3、方法中直接添加HttpServletRequest

public String hello(HttpServletRequest request,HttpServletResponse response);

4、Struts2中获取request对象

HttpServletRequest request = ServletActionContext.getRequest();
