json-lib把XML转化为json

1,依赖的jar包

Xml代码  

1.     <dependency>  
2.         <groupId>net.sf.json-lib</groupId>  
3.         <artifactId>json-lib</artifactId>  
4.         <version>2.4</version>  
5.         <classifier>jdk15</classifier>  
6.     </dependency>  
7.     <dependency>  
8.   <groupId>xom</groupId>  
9.   <artifactId>xom</artifactId>  
10.   <version>1.2.5</version>  
11. </dependency>  
12.   
13. <dependency>  
14.   <groupId>xom</groupId>  
15.   <artifactId>xom</artifactId>  
16.   <version>1.2.5</version>  
17.   <classifier>sources</classifier>  
18. </dependency>  

2,实例

Java代码  

1. @Test  
2.     public void test04() throws FileNotFoundException{  
3.         XMLSerializer xmlSerializer = new XMLSerializer();  
4.           
5.         xmlSerializer.setSkipWhitespace(false);//tObjectName("com.jn.json.bean.OrderResultResp");  
6.   
7.         InputStream ins=new FileInputStream("E:\\tmp\\orderResultRet.txt");  
8.         JSON jsonObj=xmlSerializer.readFromStream(ins);//adFromFile("E:\\tmp\\orderResultRet.txt");  
9. //      JSON jsonObj=xmlSerializer.read(str);  
10.         String jsonStr=jsonObj.toString();  
11.         System.out.println(jsonStr);  
12.           
13.     }  

 运行结果:

{"head":{"signType":"2","version":"v1.0"},"body":{"businessId":"00WGCX210027","platIdtfy":"t3","merchantId":"0044098","orderId":"2015070500017","orderDate":"20150705","detailId":[],"detailTime":"2015-07-05 15:42:35","bankId":[],"bankDealId":[],"amount":"1","amt_type":"01","payResult":"00","errCode":[],"errMsg":[],"payeeBankAccount":[],"payeeBankType":[],"payeeBankName":[],"payeeName":[],"deviceId":[],"signMsg":"b56fd6c113db486bda4d7823041de638"}}

但是有个问题:xml中没有值得竟然变成了空数组([])

解决方法:

jsonStr=jsonStr.replace("[]", "\"\"");

优化之后的程序:

Java代码  

1. @Test  
2.     public void test04() throws FileNotFoundException{  
3.         XMLSerializer xmlSerializer = new XMLSerializer();  
4.           
5.         xmlSerializer.setSkipWhitespace(false);//tObjectName("com.jn.json.bean.OrderResultResp");  
6.   
7.         InputStream ins=new FileInputStream("E:\\tmp\\orderResultRet.txt");  
8.         JSON jsonObj=xmlSerializer.readFromStream(ins);//adFromFile("E:\\tmp\\orderResultRet.txt");  
9.         String jsonStr=jsonObj.toString();  
10.         jsonStr=jsonStr.replace("[]", "\"\"");  
11.         System.out.println(jsonStr);  
12.           
13.     }
