ull}]}
使用示例：
public @TreeResponseBody List<TreeNode> getRoot() {
List<MxDepartment> list = treeBizc.listRoot(MxDepartment.class,
"superdepartmentid");//MxDepartment为po类
List<TreeNode> nodelist = new ArrayList<TreeNode>();
for (int i = 0; i < list.size(); i++) {
TreeNode node = new TreeNode();
MxDepartment mxdepartment = (MxDepartment) list.get(i);
node.setId(mxdepartment.getDepartId()); //主键的get方法
boolean hasChild =
treeBizc.hasChild( mxdepartment.getDepartId(),
MxDepartment.class,"superdepartmentid");
node.setHasChildren(hasChild);
node.setText(mxdepartment.getDepartName()==null?"":mxdepartmen
t.getDepartName());//显示字段的get方法
node.setItemType("mxdepartment"); //根节点的itemType
nodelist.add(node);
}
return nodelist;
}返回参数格式:
{"successful":true,"resultValue":{"nodes":[{"id":"000000001","tex
t":"总经理工作部
","imageUrl":null,"hasChildren":false,"itemType":"mxdepartment","
displayMode":null,"childNodes":null,"customProps":null},{},{},
{},...]},"resultHint":"","errorPage":"","type":""}
