java微信企业号开发之通讯录

上篇文章中介绍了聊天功能，这里介绍通讯录是如何实现的。首先要加载公司的所有部门，树形结构，然后点击进入部门的人员列表，点击人员能查看详细信息。 

一、界面

公司部门的树形结构：

部门成员列表： 

个人详细信息： 

二、代码实现
1.controller 

  
 @RequestMapping("/addressListDepartmentjsp.do")
 public void addressListDepartment(HttpServletRequest request, HttpServletResponse response) throws IOException{
 request.setCharacterEncoding("utf-8");
 response.setCharacterEncoding("utf-8");
 
  List jsList = addressListService.getTree();
  JSonArray jsonArray = JSONArray.fromObject(jsList);
  PrintWriter out = response.getWriter();
  out.print(jsonArray);
 }
 
 
 
 @RequestMapping("/addressListUserList.do")
 public String addressListuserList(HttpServletRequest request,HttpServletResponse response) throws UnsupportedEncodingException{
 request.setCharacterEncoding("utf-8");
 response.setCharacterEncoding("utf-8");
 String deptId=request.getParameter("Departmentid");
 String d=request.getParameter("departmentName");
 String departmentName = new String(d.getBytes("ISO-8859-1"),"utf-8");
 List userDetail = addressListService.getUserDetail(deptId);
 
 request.setAttribute("userDetail", userDetail);
 request.setAttribute("departmentName", departmentName);
 return "addressListUserList";
 }
 
 
 
 @RequestMapping("/addressListUserInfo.do")
 public String addressListuserInfo(HttpServletRequest request,HttpServletResponse response) throws UnsupportedEncodingException{
 request.setCharacterEncoding("utf-8");
 response.setCharacterEncoding("utf-8");
 
 String n=request.getParameter("name");
 String name = new String(n.getBytes("ISO-8859-1"),"utf-8");
 String mobile=request.getParameter("mobile");
 String email=request.getParameter("email");
 String weixinid=request.getParameter("weixinid");
 String avatar=request.getParameter("avatar");
 String d=request.getParameter("departmentName");
 String departmentName = new String(d.getBytes("ISO-8859-1"),"utf-8");
 request.setAttribute("name", name);
 request.setAttribute("mobile", mobile);
 request.setAttribute("email",email);
 request.setAttribute("weixinid", weixinid);
 request.setAttribute("avatar", avatar);
 request.setAttribute("departmentName", departmentName);
 
 return "addressListUserInfo";
 }

2.serviceImpl

 
 public List getTree(){
 //1.先获取token
 String accessToken = CommonUtil.getAccessToken("wxe510946434680dab", "eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0").getAccessToken();
 //2.获取部门列表
 List departmentList = AdvancedUtil.getDepartment(accessToken);
 //根据部门列表转换为页面需要的格式
 List jsList = this.convertList(departmentList);
 return jsList;
 }
 
 
 public List convertList( List departmentList)
 {
  List rootNode = new ArrayList();
  
  for (int i = 0; i < departmentList.size(); i++) {
   for (int j = i+1; j  userDetail = AdvancedUtil.getUserDetail(accessToken, deptId);
 
 return userDetail;
 }

3.工具类

//获取部门列表
public static List getDepartment(String accessToken) {
 List departmentList = null;
 // https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=ACCESS_TOKEN
 String requestUrl = "https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=ACCESS_TOKEN";
 requestUrl = requestUrl.replace("ACCESS_TOKEN", accessToken);
 
 JSonObject jsonObject = CommonUtil.httpsRequest(requestUrl, "GET", null);

 if (null != jsonObject) {
 try {
 departmentList = JSONArray.toList(jsonObject.getJSonArray("department"), Department.class);
 } catch (JSonException e) {
 departmentList = null;
 int errorCode = jsonObject.getInt("errcode");
 String errorMsg = jsonObject.getString("errmsg");
 
 }
 }
 return departmentList;
 }//获取部门成员详情
public static List getUserDetail(String accessToken,String departmentId){
 List userDetail = null;
 String requestUrl = "https://qyapi.weixin.qq.com/cgi-bin/user/list?access_token=ACCESS_TOKEN&department_id=DEPARTMENT_ID&fetch_child=1&status=0";
 requestUrl = requestUrl.replace("ACCESS_TOKEN", accessToken).replace("DEPARTMENT_ID", departmentId);
 
 JSonObject jsonObject = CommonUtil.httpsRequest(requestUrl, "GET", null);

 if (null != jsonObject) {
 try {
 userDetail = JSONArray.toList(jsonObject.getJSonArray("userlist"),UserDetail.class);
 } catch (JSonException e) {
 userDetail = null;
 int errorCode = jsonObject.getInt("errcode");
 String errorMsg = jsonObject.getString("errmsg");
 
 }
 }
 return userDetail;
 }

4.js 

 
 .ztree * {font-size: 13pt;font-family:"Microsoft Yahei",Verdana,Simsun,"Segoe UI Web Light","Segoe UI Light","Segoe UI Web Regular","Segoe UI","Segoe UI Symbol","Helvetica Neue",Arial}
 .ztree li ul{ margin:0; padding:0}
 .ztree li {line-height:30px;}
 .ztree li a {width:100%;height:30px;padding-top: 0px;border-bottom:1px #EEEEEE solid}
 .ztree li a:hover {text-decoration:none; background-color: #E7E7E7;}

 .ztree.showIcon li a span.button.switch {visibility:visible}
 .ztree li a.curSelectedNode {background-color:#D4D4D4;border:0;height:30px;}
 .ztree li span {line-height:30px;}
 .ztree li span.button {margin-top: -7px;}
 .ztree li span.button.switch {width: 16px;height: 16px;}
 
 .ztree li a.level0 span {font-size: 150%;font-weight: bold;}
 .ztree li span.button {background-image:url("images/left_menuForOutLook.png"); *background-image:url("./left_menuForOutLook.gif")}
 .ztree li span.button.switch.level0 {width: 20px; height:20px}
 .ztree li span.button.switch.level1 {width: 20px; height:20px}
 .ztree li span.button.noline_open {background-position: 0 0;}
 .ztree li span.button.noline_close {background-position: -18px 0;}
 .ztree li span.button.noline_open.level0 {background-position: 0 -18px;}
 .ztree li span.button.noline_close.level0 {background-position: -18px -18px;}
 
 

 
 
 
 
 

 
 
 
 
 

三、总结
通讯录功能并没有想象中的难，树结构采用ztree框架，后台查到的数据必须转换为ztree定义的名称，然后部门成员列表的显示和查询用到jquery mobile，在以后的文章中再介绍这种js的使用，从名字上就知道它是专门为手机页面开发的。
