使用递归展示无极限树

公司需求是 根据当前员工查找他对应整个分公司及部门的名字，思路：根据员工查找出他属于哪个分公司，拿到分公司PID（可以理解为是子公司的父节点ID），再使用递归方法依次查找，（在递归方法中只要你传父节点ID，不管其子下有没有子节点），

效果图：

 

现在贴代码：

package com.neusoft.talentbase.organization.orgunit.orgunit.vo;

import java.util.List;

import com.neusoft.talentbase.framework.core.base.vo.BaseVO;

public class MyOrgUnitVO extends BaseVO {
	/**
	 * 组织单元ID
	 */
	private long orgid;
	/**
	 * 组织单元名称
	 */
	private String orgName;

	private List<MyOrgUnitVO> list;//  存放子节点	
	private String open; // 在前台把当前节点展开	/**
	 * 父节点ID
	 */
	private long pid;


	private int isCost;

	
	private int isZhangtao;

	private int type;
	

	public int getType() {
		return type;
	}

	public void setType(int type) {
		this.type = type;
	}

	public int getIsCost() {
		return isCost;
	}

	public void setIsCost(int isCost) {
		this.isCost = isCost;
	}

	public int getIsZhangtao() {
		return isZhangtao;
	}

	public void setIsZhangtao(int isZhangtao) {
		this.isZhangtao = isZhangtao;
	}

	public long getPid() {
		return pid;
	}

	public void setPid(long pid) {
		this.pid = pid;
	}

	public List<MyOrgUnitVO> getList() {
		return list;
	}

	public void setList(List<MyOrgUnitVO> list) {
		this.list = list;
	}

	public long getOrgid() {
		return orgid;
	}

	public void setOrgid(long orgid) {
		this.orgid = orgid;
	}

	public String getOrgName() {
		return orgName;
	}

	public void setOrgName(String orgName) {
		this.orgName = orgName;
	}

	public String getOpen() {

	public void setOpen(String open) {
