json-lib把XML转化为json-白红宇

1,依赖的jar包

       Xml代码   
    <dependency>  
        <groupId>net.sf.json-lib</groupId>  
        <artifactId>json-lib</artifactId>  
        <version>2.4</version>  
        <classifier>jdk15</classifier>  
    </dependency>  
    <dependency>  
  <groupId>xom</groupId>  
  <artifactId>xom</artifactId>  
  <version>1.2.5</version>  
</dependency>  
  
<dependency>  
  <groupId>xom</groupId>  
  <artifactId>xom</artifactId>  
  <version>1.2.5</version>  
  <classifier>sources</classifier>  
</dependency>  

2,实例

       Java代码   
@Test  
    public void test04() throws FileNotFoundException{  
        XMLSerializer xmlSerializer = new XMLSerializer();  
          
        xmlSerializer.setSkipWhitespace(false);//tObjectName("com.jn.json.bean.OrderResultResp");  
  
        InputStream ins=new FileInputStream("E:\\tmp\\orderResultRet.txt");  
        JSON jsonObj=xmlSerializer.readFromStream(ins);//adFromFile("E:\\tmp\\orderResultRet.txt");  
//      JSON jsonObj=xmlSerializer.read(str);  
        String jsonStr=jsonObj.toString();  
        System.out.println(jsonStr);  
          
    }  

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   
@Test  
    public void test04() throws FileNotFoundException{  
        XMLSerializer xmlSerializer = new XMLSerializer();  
          
        xmlSerializer.setSkipWhitespace(false);//tObjectName("com.jn.json.bean.OrderResultResp");  
  
        InputStream ins=new FileInputStream("E:\\tmp\\orderResultRet.txt");  
        JSON jsonObj=xmlSerializer.readFromStream(ins);//adFromFile("E:\\tmp\\orderResultRet.txt");  
        String jsonStr=jsonObj.toString();  
        jsonStr=jsonStr.replace("[]", "\"\"");  
        System.out.println(jsonStr);  
          
    }
