 1 , constructed recursively obtaining parent method
  Private  void getUserMenus (the HashMap <String, SYSMENU> parentAndChildren, SYSMENU SYSMENU) {
         IF (! {parentAndChildren.containsKey (sysMenu.getRowId ())) 
            parentAndChildren.put (sysMenu.getRowId (), SYSMENU);

                getUserMenus (parentAndChildren, P); 
            } 
        } 
    }

 2Recursively acquire a child node
 Private  void getTreeStructure (SysMenuDto the root, List <SYSMENU> orgs) {
         for (SYSMENU ORG: orgs) {
             IF (. Org.getParentId () the equals (root.getId ())) {

                    root.setChildrens ( new new the ArrayList <> ()); 
                } 
                . root.getChildrens () the Add (S); 
            } 
        }

 3 , build tree data structure

         // get the collection of menus 
        list <SysUserFavoriteMenu> sysUserFavoriteMenuList = sysUserFavoriteMenuMapper.getSysUserFavoriteMenu (userId, DID);
         // iterate determine whether the collection

             IF (! SysUserFavoriteMenu = null ) {
                 // if the flag is set to collection collection 
                sysMenu.setIsFavorite ( ". 1" ); 
            } the else { 
                sysMenu.setIsFavorite ( " 0 " ); 
            } 
        } 
        for (sysUserFavoriteMenu sysUserFavoriteMenu: sysUserFavoriteMenuList) {

        } 
        // get the system menu version of the default settings dealer 
        String verdion = null ;
         // Gets the top menu 
        List <SYSMENU> topMenuList = sysRoleMapper.selectTopMenu (verdion);
         IF ( null == topMenuList) {
             return  null ; 
        }

        // Sort 
        list.sort ((SysMenuDto s1, SysMenuDto s2 )-> = s2.getSort s1.getSort ()> (). 1: -1? ); 
        Logger.info ( "Get the final menu: {}" , JsonUtil.obj2String (List));
         return List;
