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 

 /**
* 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

}
});

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

var zTree = $.fn.zTree.getZTreeObj("treeDemo");
zTree.expandNode(treeNode);
return false;

if(str==""){

return true;
}

// 张晓 朱丹
function getAllChildrenNodes(treeNode,result){
//var strResult=result;
if (treeNode.isParent) {
var childrenNodes = treeNode.children;
if (childrenNodes) {
 for (var i = 0; i < childrenNodes.length; i++) {
 result += ',' + childrenNodes[i].id;
 }
}
}
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。
