#ZtreeUtil

----------

更新说明：封装了部分属性（详细查看**BaseStaticTreeNode类**），支持ztree版本至3.5.34

**使用限制：静态树（一次加载所有）、必须指定根节点**

# 使用 #

----------



    public TreeNode getProjectTree() {
		List<BaseStaticTreeNode> nodeList = new ArrayList<BaseStaticTreeNode>();
		
		//声明树根节点
		nodeList.add(new BaseStaticTreeNode.Builder(EconomyConstant.VIRTUAL_BASE_TREE, "项目树", null).type("base").build());
		List<EconomyProject> projectList = this.selectList(new EntityWrapper<EconomyProject>().orderBy("RANK", true));
		for(EconomyProject projectBean:projectList){
			BaseStaticTreeNode treeNode = null;
			//指定树节点  无父节点时根节点为父节点
			if(StringUtils.isEmpty(projectBean.getPID())) {
				treeNode = new BaseStaticTreeNode.Builder(projectBean.getID(), projectBean.getNAME(), EconomyConstant.VIRTUAL_BASE_TREE).type("list").build();
			}else {
				treeNode = new BaseStaticTreeNode.Builder(projectBean.getID(), projectBean.getNAME(),projectBean.getPID()).type("project").build();
			}
			nodeList.add(treeNode);
		}
		StaticTree tree = new StaticTree(nodeList.toArray(new BaseStaticTreeNode[0]),EconomyConstant.VIRTUAL_BASE_TREE);
		//递归生成整棵树
		tree.render();
		//返回类型为TreeNode
		return tree.getRootNode();
	}


1. 生成静态树（如上）
2. 使用JSON序列化将返回值序列化为JSON对象
3.  在页面中使用`$.fn.zTree.init($("#tree"), setting, zTreeNodes);`初始化树，其中`zTreeNodes`为序列化的JSON对象
