EasyUI ComboTree SpringMVC

<select id="workUser" class="easyui-combotree" style="width:200px;"

public Object getWsWaTree(HttpServletRequest request, String id) {
        try {
            id = id == null ? "1" : id;//默认加载为pid为‘1’的数据,展开树会传参数id，传的id做为pid继续查询值。
            User user = User.getCurrUser(request);
            String depLevel = user.getOrgLevel();//机构级别
            String depId = depLevel.equals(OrgLevelConstants.ORG_WORKSHOP) ? user.getVcOrgId() : user.getVcParOrgId();//机构id

1、人员表
	VC_NUMBER 人员编号
	VC_ORG$ID 人员所属机构
	VC_NAME 人员名称

2、组织机构表
	VC_ORG$ID 机构编号
	VC_PAR$ORG$ID 父机构编号
	VC_NAME 机构名称

3、具体SQL
	select pid, id, text, state
  from (select t1.vc_org$id pid,
               t1.vc_number id,
               t1.vc_name text,
               ‘open‘ state
          from sys_t_person t1
         where t1.vc_org$id in
               (select t.vc_org$id
                  from sys_t_org t
                 start with t.vc_org$id = ‘WHBUR_WHSEG_ORG_26‘
                connect by t.vc_par$org$id = prior t.vc_org$id) and t1.vc_del = ‘0‘
        union all
        select ‘1‘ pid, t.vc_org$id id, t.vc_name text, ‘closed‘ state
          from sys_t_org t
         start with t.vc_org$id = ‘WHBUR_WHSEG_ORG_26‘
        connect by t.vc_par$org$id = prior t.vc_org$id and t.vc_del = ‘0‘)
 where pid = ‘1‘

 4、sql解释
 	1级默认为‘1’，根据一个二级机构编号（WHBUR_WHSEG_ORG_26），获取二级子目录及自己的机    构信息；
 	获取以上机构的所有人员；
 	其中关系形成树形结构；
