Struts2中使用HttpServletRequest和HttpServletResponse

一．非Ioc方式

这种方式主要是利用了com.opensymphony.xwork2.ActionContext类以及org.apache.struts2.ServletActionContext类，具体的方法如下所示。
获得request对象：

1)．HttpServletRequest request = ServletActionContext.getRequest ();

2)．ActionContext ct= ActionContext.getContext();

       HttpServletRequest request=(HttpServletRequest)ct.get(ServletActionContext.HTTP_REQUEST);

获得response对象：

1)．HttpServletResponse response= ServletActionContext.getResponse ();

2)．ActionContext ct= ActionContext.getContext();

       HttpServletResponse response=(HttpServletResponse )ct.get(ServletActionContext.HTTP_RESPONSE);

二：IOC方式

Action在继承ActionSupport的同时还要实现ServletRequestAware和ServletResponseAware接口

[java] view
plain copy

package com.iterator.action;  

  

import javax.servlet.http.HttpServletRequest;  

import javax.servlet.http.HttpServletResponse;  

  

import org.apache.struts2.interceptor.ServletRequestAware;  

import org.apache.struts2.interceptor.ServletResponseAware;  

  

import com.opensymphony.xwork2.ActionSupport;  

  

public class Struts2GetServletRequestAction extends ActionSupport implements  

        ServletRequestAware, ServletResponseAware {  

  

    private static final long serialVersionUID = 1L;  

    private HttpServletRequest request;  

    private HttpServletResponse response;  

      

    public void setServletRequest(HttpServletRequest request) {  

        this.request=request;  

    }  

  

    public void setServletResponse(HttpServletResponse response) {  

        this.response=response;  

    }  

  

    @Override  

    public String execute() throws Exception {  

        System.out.println("requestUsername=" + request.getParameter("username") + ",requestPassword=" + request.getParameter("password"));  

        return SUCCESS;  

    }  

}
