Vijava 学习笔记之数据中心下（集群和非集群的资源池和ESXI）树形结构展示

实体对象：DtreeObj.java

package com.vmware.pojo;/** * Created by vixuan-008 on 2015/6/27. */public class DtreeObj {    private int id;//编号    private String name;//name    private int pid;//父类id    private int type;//设备类型    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public int getPid() {        return pid;    }    public void setPid(int pid) {        this.pid = pid;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public int getType() {        return type;    }    public void setType(int type) {        this.type = type;    }}

逻辑方法：ClusetDemo.java
