部门树递归

public class Dept {
private static final long serialVersionUID = 1L;
/**
* 部门名称
*/
@ApiModelProperty(value = "部门名称")
private String name;
/**
* 部门负责人ID
*/
private Long manager;
@TableField("parent_id")
private Long parentId;
@TableField("data_authority")
private Long dataAuthority;
}
@Override
public Map<String, Object> deptTree() {
List<Map<String,Object>> list = subDeptTree(1L);
Map<String, Object> map = new HashMap<String,Object>();
map.put("id",1L);
map.put("name","全公司");
map.put("parentId",0L);
map.put("subDept",list);
return map;
}
/**
* 功能：生成子部门树信息
* @param id

*/
private List<Map<String, Object>> subDeptTree(Long id) {
List<Map<String, Object>> list = new ArrayList<Map<String,Object>>();
EntityWrapper<Dept> entityWrapper = new EntityWrapper<Dept>();
entityWrapper.eq("parent_id",id);
List<Dept> deptList = deptDao.selectList(entityWrapper);

}
return list;
}
