工作总结，用extjs、mybatis、springMVC实现树形显示班级
前台extjs实现树形代码如下：
xtype : ‘combotree‘,
fieldLabel : ‘部门名称‘,
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
}
后台，controller代码
/**
* 查找带check的部门树
*
* @return
*/
@RequestMapping(value="/getDeptList",method = RequestMethod.POST)
@ResponseBody
public List<Tree> getDeptList() {
Criteria criteria = new Criteria();
return gradeCourseService.getDeptList(criteria);
}
dao层代码：
/**
*
* 方法描述 : 查询部门
* @param criteria
* @return list<Dept>集合
*/
List<Dept> getDeptList(Criteria criteria);
dao对应的mapper查询代码：
<!-- 查询学生部门 -->
<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>
<!-- 树叶模型 -->
<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层代码：
/**
* 获取部门下拉框列表
* @return
*/
List<Tree> getDeptList(Criteria criteria);
service层实现类代码：
public List<Tree> getDeptList(Criteria 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("河北金融学院")){
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){//这是判断系节点是不是没有子节点。如果没有，就让系变为叶子节点。
// treeNode.setLeaf(true);//变为叶子节点。
// }
resultTree.add(treeNode);
}
return resultTree;
}
