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

 

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;
    }
}
