ExtJS, the realization of the tree-shaped structure of the summary

Work summary, with ExtJS, MyBatis, Springmvc to realize the tree-shaped display class

The foreground ExtJS implements the tree code as follows:

Xtype: ' Combotree ',
Fieldlabel: ' Department name ',
Name: ' DeptID ',
Hiddenname: ' DeptID ',
Allowblank:false,
width:235,
Tree:new Ext.tree.TreePanel ({
Root: {
Expanded:true,
ID: ' Root '
},
Loader:new Ext.tree.TreeLoader ({
Dataurl: ' Dept/getdeptlist '
}),
Animate:true,
Enabledd:true,
Autoscroll:true,
height:400,
Rootvisible:true
}),
Listeners: {
Select:function (Combotree) {
}
},
Scope:this
}

Backstage, controller code

/**
* Find a departmental tree with check
*
* @return
*/
@RequestMapping (value= "/getdeptlist", method = Requestmethod.post)
@ResponseBody
Public list<tree> getdeptlist () {
criteria = new criteria ();
return gradecourseservice.getdeptlist (criteria);
}

DAO Layer Code:

/**
*
* Method Description: Query department
* @param criteria
* @return list<dept> Collection
*/
List<dept> getdeptlist (criteria);

DAO corresponds to the Mapper query code:

<!--Inquiry Student Department--
<select id= "getdeptlist" parametertype= "Criteria" resultmap= "Depetmap" >
Select
a.dept_id DeptID,
A.dept_name Deptname,
A.leaf Leaf,
b.dept_id Deptpartpid,
B.dept_name Deptpartname
From spauth.base_dept a,spauth.base_dept b
where
A.dept_type = ' 2 '
and

a.dept_id = B.dept_pid
Order
by a.dept_id ASC,
b.dept_id ASC
</select>
<!--leaf Models--
<resultmap type= "cn.edu.hbcf.privilege.pojo.Dept" id= "Depetmap" >
<id property= "DeptID" column= "DeptID"/>
<result property= "Deptname" column= "Deptname"/>
<result property= "leaf" column= "leaf"/>
<collection property= "Children" oftype= "cn.edu.hbcf.privilege.pojo.Dept" >
<id property= "DeptID" column= "Deptpartpid"/>
<result property= "Deptname" column= "Deptpartname"/>
</collection>
</resultMap>

Service Layer Code:

/**
* Get a list of department drop-down boxes
* @return
*/
List<tree> getdeptlist (criteria);

Service Layer Implementation Class code:

Public list<tree> Getdeptlist (criteria) {
list<tree> resulttree = new arraylist<tree> ();
Tree treeNode = null;
list<dept> deptlist = gradecoursemapper.getdeptlist (criteria);
Dept Dept = null;
for (iterator<dept> it = Deptlist.iterator (); It.hasnext ();) {
TreeNode = new Tree ();
List<tree> childtree =new arraylist<tree> ();
Tree childnode = null;
Dept childept = null;
Dept = It.next ();
if (Dept.getdeptname (). Equals ("Hebei Finance Institute")) {
Continue;
}
Treenode.settext (Dept.getdeptname ());
Treenode.setid (Dept.getdeptid ());
for (iterator<dept> iter = Dept.getchildren (). Iterator (); Iter.hasnext ();) {
Childnode = new Tree ();
Childept = Iter.next ();
Childnode.settext (Childept.getdeptname ());
Childnode.setid (Childept.getdeptid ());
Childnode.setleaf (TRUE);
Childtree.add (Childnode);
Treenode.setchildren (Childtree);
}
if (Treenode.getchildren (). Size () ==0) {//This is the judgment that the node is not a child node. If not, let the system become a leaf node.
Treenode.setleaf (TRUE);//becomes a leaf node.
//            }
Resulttree.add (TreeNode);
}
return resulttree;
}
