Gets all the roles of the user and puts the role ID into the string and into the custom attribute in the Ztreecomm class Diyparams

Ztreecomm should be the corresponding sys_authority table, but there is no field in the table corresponding to Roleid, so the entity class stores roleid as strings in Ztree

Next determine whether the root node,//ID is empty, initial load, query root node,//ID is not empty, drop-down, query child node

<!---    < id = "Getauthorityroot"  Resultmap= "Authoritytreeresultmap"  parametertype= "Ztreecomm">         SELECT * from Sys_authority where authority_id in (            SELECT authority_id from sys_role_authority where INST R (#{diyparams},role_id) >0        ) and        parent_id is NULL and authority_type= ' 2 '    </ Select >

Authority_type Permission Type: 1: normal permission 2: Menu 3: report

When you get a collection of permissions, determine what the parent node is for each permission

 for (int i = 0; i < tree.size (); i++) {                = (ztreecomm) tree.get (i);                 int total = sysuserservice.isparent (ztree);                ! = 0? Constants.IS_TRUE:Constants.IS_FALSE);                Votree.add (Ztree);            }

<!---    < id = "Isparent" Resulttype  = "integer"  parametertype= "Ztreecomm">        Select COUNT (* ) from Sys_authority WHERE parent_id=#{id} and Authority_type= ' 2 '    </Select  >

and assign values to each Ztree isparent into the new set.

To sort a new collection

// 4, List sort.             New comparator<ztreecomm>() {                publicint  Compare ( Ztreecomm arg0, Ztreecomm arg1) {                    return  arg0.getsortno (). CompareTo (Arg1.getsortno ());                }            });
