在JS中,将显示树的url地址写成control的地址即可.

control:

复制代码 代码如下:

@RequestMapping(value = "/tree")

public void tree(HttpServletRequest request, HttpServletResponse response) throws IOException {

this.writeJson(response, bookService.getTree());

}

dao:

复制代码 代码如下:

/**

* 获取树

*/

@Override

public List<Tree> getTree(){

try {

List<Tree> trees = new ArrayList<Tree>();

List<TBookType> root = this.search(0);

if(root != null && root.size() > 0){

for(TBookType tb : root){

Tree rootnode = this.getNode(tb);

rootnode.setState("open");

trees.add(rootnode);

}

}

return trees;

} catch (Exception e) {

e.printStackTrace();

return null;

}

}

/**

* 递归

*/

private Tree getNode(TBookType node){

if(node == null){

return null;

}

try {

Tree treenode = new Tree();

treenode.setId(String.valueOf(node.getId()));

treenode.setText(node.getName());

treenode.setPid(String.valueOf(node.getPid()));

List<TBookType> children = this.search(node.getId());

if(children != null && children.size() > 0){

treenode.setState("closed");

for(TBookType child : children){

Tree childnode = this.getNode(child);

if(childnode != null){

treenode.getChildren().add(childnode);//递归

}

}

}

return treenode;

} catch (Exception e) {

throw new BusinessException("获取数据出错!", e);

}

}

以上就是使用EasyUI实现同步树的全部核心代码了，希望大家能够喜欢。
