1、先下载插件引入到项目中:

<%@ page import="net.sf.json.JSONArray"%>
<%
List<String> tagList = new ArrayList<String>();
if(null!=request.getAttribute("list")){
tagList = (List<String>)request.getAttribute("list");
}

var log, className = "dark";
function beforeDrag(treeId, treeNodes) {
return false;
}
function zTreeOnMouseUp(event, treeId, treeNode) {
var treeObj = $.fn.zTree.getZTreeObj("treeDemo");
var nodes = treeObj.getSelectedNodes();
if (nodes.length>0) {
treeObj.cancelSelectedNode(nodes[0]);
}
};
function beforeRemove(treeId, treeNode) {
className = (className === "dark" ? "":"dark");
showLog("[ "+getTime()+" beforeRemove ]     " + treeNode.name);
return confirm("确认删除节点 -- " + treeNode.name + " 吗？");
}
function onRemove(e, treeId, treeNode) {
showLog("[ "+getTime()+" onRemove ]     " + treeNode.name);
}
function beforeRename(treeId, treeNode, newName) {
if (newName.length == 0) {
alert("节点名称不能为空.");
var zTree = $.fn.zTree.getZTreeObj("treeDemo");
setTimeout(function(){zTree.editName(treeNode)}, 10);
return false;
}
$.ajax({

data: {Id:treeNode.id,name:newName},
dataType: "json",
success: function(res){
alert("修改成功");
}
});
return true;
}
function showLog(str) {
if (!log) log = $("#log");
log.append("<li class=‘"+className+"‘>"+str+"</li>");
if(log.children("li").length > 8) {
log.get(0).removeChild(log.children("li")[0]);
}
}
function getTime() {
var now= new Date(),
h=now.getHours(),
m=now.getMinutes(),
s=now.getSeconds(),
ms=now.getMilliseconds();
return (h+":"+m+":"+s+ " " +ms);
}

function addNode(pId,name){
$.ajax({

url: "/momo/org/addDept.do",
data: {pId:pId,name:name},
dataType: "json",
success: function(res){
alert(res.success)
}
});
}

2、后台代码:

　　controller层：

public class OrgController extends BaseController{

@Resource
private OrgService orgService;

@RequestMapping("/index")
public String index(HttpServletRequest request,Model mod){
int companyId=51;
List<String> list=orgService.getRootDept(companyId);
mod.addAttribute("list", list);
return "org/index";
}

@RequestMapping("/addDept")
@ResponseBody
public Object addDept(HttpServletRequest request,Model mod,String pId,String name){
System.out.println(pId+"----"+name);
int companyId=51;
String Id=orgService.addRootDept(companyId,pId,name);
Map<String, Object> resultMap = new HashMap<String, Object>();
resultMap.put("success", true);
resultMap.put("Id", Id);
return resultMap;
}

@RequestMapping("/uptDept")
@ResponseBody
public Object uptDept(HttpServletRequest request,Dept dept){
int companyId=51;
orgService.uptDept(companyId,dept.getId(),dept.getName());
Map<String, Object> resultMap = new HashMap<String, Object>();
resultMap.put("success", true);
return resultMap;
}

@RequestMapping("/delDept")
@ResponseBody
public Object delDept(HttpServletRequest request,Dept dept,String type){
int companyId=51;
orgService.delDept(companyId,dept.getId(),type);
Map<String, Object> resultMap = new HashMap<String, Object>();
resultMap.put("success", true);
return resultMap;
}
}

service层:

public class OrgServiceImpl implements OrgService{

@Resource
private OrgDao orgDao;

@Override
public List<String> getRootDept(int companyId) {
List<Dept> deptList=orgDao.getRootDept(companyId);
List<String> list=new ArrayList<String>();
for (int i = 0; i < deptList.size(); i++) {
String str="";
str="{id:\""+deptList.get(i).getId()+"\", pId:\""+deptList.get(i).getpId()+"\", name:\""+deptList.get(i).getName()+"\"}";
list.add(str);
}

return list;
}

@Override
public String addRootDept(int companyId, String pId, String name) {
String Id=RandomStringUtils.randomAlphanumeric(5);
Dept dept=new Dept();
dept.setId(Id);
dept.setpId(pId);
dept.setName(name);
dept.setCompanyId(companyId);
dept.setCreatetime(new Date());
orgDao.addRootDept(dept);

return Id;
}

@Override
public void uptDept(int companyId, String Id, String name) {
orgDao.uptDept(Id,name);
}

private static List<Dept> getChildNodeIds(List<Dept> targetList,List<Dept> list,String Id){
for(int i=0;i<list.size();i++){
//遍历出父id等于参数的id，add进子节点集合
if(list.get(i).getpId().equals(Id)){
//递归遍历下一级
getChildNodeIds(targetList,list,list.get(i).getId());
targetList.add(list.get(i));
}
}
return targetList;
}

@Override
public void delDept(int companyId, String Id,String type) {
List<Dept> targetList=new ArrayList<Dept>();

List<Dept> deptList=orgDao.getRootDept(companyId);//所有目录
List<Dept> childList=getChildNodeIds(targetList,deptList,Id);

for(int i=0;i<childList.size();i++){
orgDao.delDept(childList.get(i).getId());
}
if(type.equals("0")){
orgDao.delDept(Id);
}
}

}

dao层：

public interface OrgDao {

public void addRootDept(Dept dept);

public List<Dept> getRootDept(int companyId);

public void uptDept(@Param("Id")String Id, @Param("name")String name);

public void delDept(String Id);

public List<Dept> getChildNode(String Id);

}

bean:

public class Dept {

private String Id;
private String pId;
private String name;
private int companyId;
private Date createtime;

public String getId() {
return Id;
}
public void setId(String id) {
Id = id;
}
public String getpId() {
return pId;
}
public void setpId(String pId) {
this.pId = pId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getCompanyId() {
return companyId;
}
public void setCompanyId(int companyId) {
this.companyId = companyId;
}
public Date getCreatetime() {
return createtime;
}
public void setCreatetime(Date createtime) {
this.createtime = createtime;
}
}

mapper-org.xml:

<mapper namespace="com.bjpowernode.pmes.dao.OrgDao">
<select id="getRootDept" parameterType="int" resultType="com.bjpowernode.pmes.bean.Dept">
select * from webcast_org where companyid=#{companyId} order by createtime asc
</select>

<insert id="addRootDept" parameterType="com.bjpowernode.pmes.bean.Dept" useGeneratedKeys="true" keyProperty="Id">
insert into webcast_org(
id,
pid,
name,
companyid,
createtime
)values(
#{id},
#{pId},
#{name},
#{companyId},
#{createtime}
)
</insert>

<update id="uptDept" parameterType="map">
update webcast_org set name=#{name} where id=#{Id}
</update>

<delete id="delDept" parameterType="String">
delete from webcast_org where id=#{Id}
</delete>
</mapper>

还有个小问题就是怎么取消节点选中状态：

在callback中添加onMouseUp: zTreeOnMouseUp 就可以了

function zTreeOnMouseUp(event, treeId, treeNode) {
var treeObj = $.fn.zTree.getZTreeObj("treeDemo");
var nodes = treeObj.getSelectedNodes();
if (nodes.length>0) {
treeObj.cancelSelectedNode(nodes[0]);
}
};

需要增加其他功能的还得看API文档。
