XML转JSON

Step 1 : 下载 java-json.jar

http://www.java2s.com/Code/JarDownload/java/java-json.jar.zip

Step 2: 增加 java-json.jar 到/libs目录并add to build path.

Step 3: 测试demo

package test;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import org.json.XML;

public class Test {
	public static String signData = "<?xml version="1.0" encoding="utf-8"?><BodSignData version="1.0"><Field><Name>orderId</Name><DispName></DispName><Value>5001</Value></Field><Field><Name>payAccountNo</Name><DispName>kevin</DispName><Value>590000113004775</Value></Field><Field><Name>amount</Name><DispName>undefined</DispName><Value>520</Value></Field><Field><Name>masterName</Name><DispName>undefined</DispName><Value>sn</Value></Field><Field><Name>payDate</Name><DispName>undefined</DispName><Value>20150704</Value></Field></BodSignData>";
