EasyUI ComboTree SpringMVC

1、涉及技术：

　　EasyUI

　　Spring MVC

2、jsp前端代码：

　　

<select id="workUser" class="easyui-combotree" style="200px;"
                    data-options="url:'/csmis/csmisEquadjust/wswatree.action',required:true" multiple>
</select>

3、java后台代码

　　

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
            String sqlStr = "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 = '" + depId + "' " +
                    " connect by t.vc_par$org$id = prior t.vc_org$id)  and t1.vc_del = '0' and t1.vc_server = '" + SystemConstants.SERVER_ID + "' " +
                    " union all " +
                    " select '1' pid,t.vc_org$id id,t.vc_name text,'closed' state from sys_t_org t start with t.vc_org$id = '" + depId + "' " +
                    " connect by t.vc_par$org$id = prior t.vc_org$id and t.vc_del = '0' and t.vc_server = '" + SystemConstants.SERVER_ID + "') " +
                    " where pid = '" + id + "'";

            logger.info("sqlStr::: " + sqlStr);
            return jdbcTemplate.query(sqlStr, BeanPropertyRowMapper.newInstance(EasyUIComboTree.class));
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return null;
    }

 4、封装实体类

　　

        private String id;
	private String pid;
	private String text;
	private List<EasyUIComboTree> children;
	private String state = "closed";

 5、数据库表数据结构及SQL

　　

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；

6、具体效果

　　

7、多选默认选中

　　

$('#workUserId').combotree({
                onLoadSuccess: function (node,data) {
                     var t = $("#workUserId").combotree('tree');//获取tree  
                     for(var i=0;i<data.length ;i++ ){
                        node= t.tree("find",data[i].id);  
                        t.tree('expandAll',node.target);//展开所有节点  
                     }

                     $('#workUserId').combotree('setValues','${map.workUser}');//combotree 多选设置默认值
                }
            });
