java代码解析json对象获取json对象属性值

工作中用到java代码解析JSON对象属性，在网上搜索了下，发现写的都不太完整，自己整理了下，写了个测试类.

说明：解析JSON需要用到 架包，下载地址：/detail/wtingting5211314/7641749

 

代码如下：

 

package ;

import ;
import ;

public class TestJson {

 /**
  * @param args
  */
 public static void main(String[] args) {
  
  String JsonStr = "{data:["
            +"{id: '1', code: 'app1', name: 'app1', classifierId: 'Root', alterationType: '', parentId: '#', attributes: {} },"
            +"{id: '2', code: 'app1_db1', name: 'xx', classifierId: 'Catalog', alterationType: '', parentId: '1', attributes: {}},"
            +"{id: '3', code: 'edw', name: 'xx', classifierId: 'Schema', alterationType: '', parentId: '2', attributes: {}},"
            +"{id: '4', code: 'Table1', name: '表1', classifierId: 'Table', alterationType: '', parentId: '3', attributes: {}},"
            +"{id: '5', code: 'Column1', name: '字段1', classifierId: 'Column', alterationType: 'delete', parentId: '4', attributes: {length: 20, dataType: 'varchar'}},"
            +"{id: '6', code: 'Column2', name: '字段2', classifierId: 'Column', alterationType: 'add', parentId: '4', attributes: {length: 20, dataType: 'varchar'}}"
            +"]}";
  
  
  try {
   parseJsonToBeanInfo(JsonStr);
  } catch (Exception e) {
   ();
  }
  
 }
 
 public static void parseJsonToBeanInfo(String JsonInfo) throws Exception {

  if(!"".equals(JsonInfo)&&JsonInfo!=null){
   
   //先把String 形式的 JSON 转换位 JSON 对象
   JSONObject json = new JSONObject(JsonInfo);
   //得到 JSON 属性对象列表
   JSONArray jsonArray =("data");
   //遍历，得到属性值
   for (int i = 0; i < (); i++) {
    JSONObject jo = (i);
    String id = ("id");
    String name = ("name");
    String parentId = ("parentId");
    String alterationType = ("alterationType");

    ("id is:"+id);
    (" name is:"+name);
    (" parentId is:"+parentId);
    (" alterationType is:"+alterationType);
   } 
  } 
 }
}

 

运行结果如下：

id is:1 name is:app1 parentId is:# alterationType is:
id is:2 name is:xx parentId is:1 alterationType is:
id is:3 name is:xx parentId is:2 alterationType is:
id is:4 name is:表1 parentId is:3 alterationType is:
id is:5 name is:字段1 parentId is:4 alterationType is:delete
id is:6 name is:字段2 parentId is:4 alterationType is:add
