Java 开发webservice 并将数据入库

最近开发一套webservice的短信接口。通过webservice对短信数据操作。测试类如下：
public static void main(String[] args) {
try {  
Service srvcModel = new ObjectServiceFactory().create(ISmsInbox.class);  
XFireProxyFactory factory =  new XFireProxyFactory(XFireFactory.newInstance().getXFire());  
String URL ="http://127.0.0.1/SendMessage/services/SmsInbox";  
ISmsInbox srvc = (ISmsInbox)factory.create(srvcModel, URL); 
SmsInbox smsInbox=new SmsInbox();
smsInbox.setApplicationid("1");
smsInbox.setExtcode("23");
smsInbox.setMassmsid("1");
smsInbox.setMessagecontent("ok");
smsInbox.setMsgfmt(1);
smsInbox.setReceivetime(new Date());
smsInbox.setRequesttime(new Date());
smsInbox.setSourceaddr("11");
srvc.save(smsInbox);
} catch (MalformedURLException e) 
{    
e.printStackTrace();    
}   }

webservice接口
 /**
     *  存储实体到数据库
     */
    public void save(T entity) {
     try {
     System.out.println("执行保存操作....");
     if(entity !=null){
     getHibernateTemplate().save(entity);
     }
     else{
     System.out.println("enity为空");
     }
    
} catch (Exception e) {
e.printStackTrace();
}
    
    }

//当调用保存操作时。异常如下
