本人以前做了几年j2ee的开发，最近突然接手一个android项目服务端用的ssh2框架，android客户端用的volley通信交互框架，下面简单介绍下ssh2怎么给通过volley给android端提供json数据。

一、ssh2端代码
struct配置文件：

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts>  <package  name="struts2" extends="json-default" namespace="/">    <!-- admin -->    <action name="getAllCunZhuang" class="AdminAction" method="getAllCunZhuang"></action> </package></struts>

ssh2服务端代码：

/**     * 查询所有村庄     */public void getAllCunZhuang(){        List<Tcunzhuang> assignmentList=this.adminUserService.getAllCunZhuang();        JSONArray jsArr=new JSONArray();        JSONObject jsObj=new JSONObject();        Tcunzhuang cunzhuang;//        for(int i=0;i<assignmentList.size();i++){            cunzhuang=assignmentList.get(i);            jsObj.clear();            jsObj.put("id", cunzhuang.getId());            jsObj.put("name",cunzhuang.getName());            jsArr.add(jsObj);        }    JSArr=jsArr;    this.writeJson(JSArr);}

二：android客户端代码

请求参数：

package com.gnnu.orange;public class Config {    //改成自己本机IP    public static final String USER_LOGIN_URL = "http://192.168.1.108:8080/GnOrangeBackground/publicJSP/user.jsp";    public static final String USER_QA_URL = "http://192.168.1.108:8080/GnOrangeBackground/publicJSP/qa.jsp";    public static final String USER_Q_URL = "http://192.168.1.108:8080/GnOrangeBackground/publicJSP/question.jsp";    public static final String USER_QIMG_URL = "http://192.168.1.108:8080/GnOrangeBackground/publicJSP/questionimg.jsp";    public static final String USER_QPATH_URL = "http://192.168.1.108:8080/GnOrangeBackground/publicJSP/imagepath.jsp";    public static final String test = "http://111.75.158.12:8081/nongShangInformation/getAllCunZhuang";}

打印结果：
这里写图片描述

这样就获取一个json数组了。
