java转json 报错处理机制 案例 .(四)

String json = "{name=\"json\",bool:true,int:1,double:2.2,func:function(a){ return a; },array:[1,2]}";
JSONObject jsonObject = JSONObject.fromString(json);
Object bean = JSONObject.toBean( jsonObject );
assertEquals( jsonObject.get( "name" ), PropertyUtils.getProperty( bean, "name" ) );
assertEquals( jsonObject.get( "bool" ), PropertyUtils.getProperty( bean, "bool" ) );
assertEquals( jsonObject.get( "int" ), PropertyUtils.getProperty( bean, "int" ) );
assertEquals( jsonObject.get( "double" ), PropertyUtils.getProperty( bean, "double" ) );
assertEquals( jsonObject.get( "func" ), PropertyUtils.getProperty( bean, "func" ) );
List expected = JSONArray.toList( jsonObject.getJSONArray( "array" ) );
assertEquals( expected, (List) PropertyUtils.getProperty( bean, "array" ) );

Java代码
String json = "{\"value\":\"xx\",\"row\":1,\"col\":1}";
JSONObject jsonObject = JSONObject.fromString(json);
JsonBean2 bean = (JsonBean2) JSONObject.toBean( jsonObject, JsonBean2.class );
assertEquals( jsonObject.get( "col" ),new Integer( bean.getCol()) );
assertEquals( jsonObject.get( "row" ), new Integer( bean.getRow() ) );
assertEquals( jsonObject.get( "value" ), bean.getValue() );

String json = "{\"value\":\"xx\",\"row\":1,\"col\":1}";
JSONObject jsonObject = JSONObject.fromString(json);
JsonBean2 bean = (JsonBean2) JSONObject.toBean( jsonObject, JsonBean2.class );
assertEquals( jsonObject.get( "col" ),new Integer( bean.getCol()) );
assertEquals( jsonObject.get( "row" ), new Integer( bean.getRow() ) );
assertEquals( jsonObject.get( "value" ), bean.getValue() );

6 json to xml
1)
JSONObject json = new JSONObject( true );
String xml = XMLSerializer.write( json );

2)
JSONObject json = JSONObject.fromObject("{\"name\":\"json\",\"bool\":true,\"int\":1}");
String xml = XMLSerializer.write( json );

json
true
1


json
true
1

3)
JSONArray json = JSONArray.fromObject("[1,2,3]");
String xml = XMLSerializer.write( json );

1
2
3

7 、xml to json


return matrix[i][j];




return matrix[i][j];



JSONArray json = (JSONArray) XMLSerializer.read( xml );
System.out.println( json );
// prints [function(i,j){ return matrix[i][j]; }]

在Java中加上这几个包

实例：

import java.io.IOException;
import java.util.ArrayList;
import java.sql.Date;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
import aa.JsonBean2;

public class main extends HttpServlet {

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

List list = new ArrayList();
JsonBean2 jb1 = new JsonBean2();
jb1.setA(1);
jb1.setB("丁龙飞");
System.out.println("*****123");
Date c=new Date(100,9,10);
String s=c.t
