java微信企业号开发之通讯录_java

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 

  /**
 * 加载部门列表
 */
 @RequestMapping("/addressListDepartmentjsp.do")
 public void addressListDepartment(HttpServletRequest request, HttpServletResponse response) throws IOException{
 request.setCharacterEncoding("utf-8");
 response.setCharacterEncoding("utf-8");

  List<JsonTree> jsList = addressListService.getTree();
  JSONArray jsonArray = JSONArray.fromObject(jsList);
  PrintWriter out = response.getWriter();
  out.print(jsonArray);
 }

 /**
 * 加载部门成员列表
 */
 @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> userDetail = addressListService.getUserDetail(deptId);

 request.setAttribute("userDetail", userDetail);
 request.setAttribute("departmentName", departmentName);
 return "addressListUserList";
 }

 /**
 * 查看员工详细信息
 */
 @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

 /**
 * 加载部门列表
 */
 public List<JsonTree> getTree(){
 //1.先获取token
 String accessToken = CommonUtil.getAccessToken("wxe510946434680dab", "eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0").getAccessToken();
 //2.获取部门列表
 List<Department> departmentList = AdvancedUtil.getDepartment(accessToken);
 //根据部门列表转换为页面需要的格式
 List<JsonTree> jsList = this.convertList(departmentList);
 return jsList;
 }

 /**
 * 转为ZTree的格式
 */
 public List<JsonTree> convertList( List<Department> departmentList)
 {
  List<JsonTree> rootNode = new ArrayList<JsonTree>();

  for (int i = 0; i < departmentList.size(); i++) {
   for (int j = i+1; j <departmentList.size(); j++) {
   if (departmentList.get(i).getId()==departmentList.get(j).getParentid()) {
  JsonTree jt = new JsonTree();
  jt.setId(departmentList.get(i).getId());
  jt.setName(departmentList.get(i).getName());
  jt.setpId(departmentList.get(i).getParentid());
  jt.setOpen(false);
  jt.setUrl("");
  rootNode.add(jt);
  break;
 }else {
  JsonTree jt = new JsonTree();
  jt.setId(departmentList.get(i).getId());
  jt.setName(departmentList.get(i).getName());
  jt.setpId(departmentList.get(i).getParentid());
  jt.setOpen(false);
  jt.setUrl("addressListUserList.do?Departmentid="+departmentList.get(i).getId()+"&departmentName="+departmentList.get(i).getName());

  rootNode.add(jt);
  break;
 }
 }

 }
  return rootNode;
 }

 /**
 * 加载部门成员列表
 */
 public List<UserDetail> getUserDetail(String deptId){
 //1.先获取token
 String accessToken = CommonUtil.getAccessToken("wxe510946434680dab", "eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0").getAccessToken();

 //2.根据部门id和token的值获取部门成员列表
 List<UserDetail> userDetail = AdvancedUtil.getUserDetail(accessToken, deptId);

 return userDetail;
 }

3.工具类

//获取部门列表
public static List<Department> getDepartment(String accessToken) {
 List<Department> 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<UserDetail> getUserDetail(String accessToken,String departmentId){
 List<UserDetail> 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

 var setting = {

 }
 });

 function addDiyDom(treeId, treeNode) {
 var spaceWidth = 5;
 var switchObj = $("#" + treeNode.tId + "_switch"),

 zTree.expandNode(treeNode);

 return true;

// 张晓 朱丹
 function getAllChildrenNodes(treeNode,result){
 //var strResult=result;
 if (treeNode.isParent) {
 var childrenNodes = treeNode.children;
 if (childrenNodes) {

 return result;

 $(document).ready(function(){

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。
