Ajax - Struts2 与 Ajax

作者:dayu

涉及

  Struts.xml、return "success"、return null、request.getWrite().write(str)

  Ajax、success: function(data){}

关于 request.getWrite().write(s)

package com.ikoo;

import java.io.IOException;
import java.io.PrintWriter;// java.io

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;// struts2
import org.junit.Test;

public class TestWrite {
    @Test
    public void test(String s) {
        HttpServletResponse response = ServletActionContext.getResponse();// 这里用的Struts2
        response.setCharacterEncoding("UTF-8");
        response.setContentType("text/html;charset=UTF-8");
        try {
            PrintWriter printWriter = response.getWriter();
            printWriter.write(s);
            // response.getWriter().write(s);
            // 作用:直接向客户端页面返回数据(将数据直接写到客户端页面上)
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
