EASYUI 树形菜单 fastjson JAVA嵌套对象转JSON

使用EASYUI 的树形导航菜单 JAVA对象转菜单

我用的是JDK1.8 使用 fastjson1.2.7版本 从github下载下来的源代码

EasyUiTree.java对象代码如下：

package org.bingley.test;

import java.io.Serializable;

import java.util.List;

import java.util.Map;

/**

*/

public class EasyUiTree implements Serializable {

 /**

  *

  */

 private static final long serialVersionUID = 3714827586565908167L;

 private String id;

 private String text;

 private String state;

 private String checked;

 private Map<String,String> attributes;

 private List<EasyUiTree> children;

 public String getId() {

  return id;

 }

 public void setId(String id) {

  this.id = id;

 }

 public String getText() {

  return text;

 }

 public void setText(String text) {

  this.text = text;

 }

 public String getState() {

  return state;

 }

 public void setState(String state) {

  this.state = state;

 }

 public String getChecked() {

  return checked;

 }

 public void setChecked(String checked) {

  this.checked = checked;

 }

 public Map<String, String> getAttributes() {

  return attributes;

 }

 public void setAttributes(Map<String, String> attributes) {

  this.attributes = attributes;

 }

 public List<EasyUiTree> getChildren() {

  return children;

 }

 public void setChildren(List<EasyUiTree> children) {

  this.children = children;

 }

 

 

}

 

测试代码如下：

package org.bingley.test;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import com.alibaba.fastjson.JSON;

/**@ClassName: TestJsonTree

public class TestJsonTree {

 public static void main(String[] args) {

  

  EasyUiTree tree1=new EasyUiTree(); 

   tree1.setText("根菜单");

   List<EasyUiTree> treenode=new ArrayList();

   for (int i=0;i<3;i++)

   {

    EasyUiTree tree=new EasyUiTree();

    tree.setText("一级"+i);   

    List<EasyUiTree> child=new ArrayList();

    for (int j=0;j<4;j++)

    {

     EasyUiTree stree=new EasyUiTree();

    stree.setText("二级菜单"+i+""+j);

    Map<String,String> map=new HashMap();

    map.put("url", "url"+j);

    stree.setAttributes(map);

     child.add(stree);   

    }

    tree.setChildren(child);

    treenode.add(tree);

    }

  

   tree1.setChildren(treenode);

  

   String str=""; 

   System.out.println("test 开始转化");

  str=  JSON.toJSONString(tree1);

 System.out.println(str);

System.exit(0);

 

 

 }

}

执行结果如下：

{"children":[{"children":[{"attributes":{"url":"url0"},"text":"二级菜单00"},{"attributes":{"url":"url1"},"text":"二级菜单01"},{"attributes":{"url":"url2"},"text":"二级菜单02"},{"attributes":{"url":"url3"},"text":"二级菜单03"}],"text":"一级0"},{"children":[{"attributes":{"url":"url0"},"text":"二级菜单10"},{"attributes":{"url":"url1"},"text":"二级菜单11"},{"attributes":{"url":"url2"},"text":"二级菜单12"},{"attributes":{"url":"url3"},"text":"二级菜单13"}],"text":"一级1"},{"children":[{"attributes":{"url":"url0"},"text":"二级菜单20"},{"attributes":{"url":"url1"},"text":"二级菜单21"},{"attributes":{"url":"url2"},"text":"二级菜单22"},{"attributes":{"url":"url3"},"text":"二级菜单23"}],"text":"一级2"}],"text":"根菜单"}
