服务器代码：（axis2 + hibernate + spring）

public class HxcNewsService implements IHxcNewsService {    
    private IDao dao;   
    public void setDao(IDao dao) {
        this.dao = dao;
    }
    public HxcNews find(int id){
        return (HxcNews) dao.find("com.ews.bean.HxcNews",id);
    }
}

public class Dao<T> extends HibernateDaoSupport implements IDao<T> {

    public T find(String str,int id) {

        try {
            T t = (T) getHibernateTemplate().get(str, id);
            return t;
        } catch (RuntimeException re) {         
            throw re;
        }

    }

}

客户代码：

public class Test {
    public static void main(String[] args) {
        try {
            HxcNewsServicePortType hxcNewsServicePortType = new HxcNewsServiceLocator().getHxcNewsServiceHttpSoap12Endpoint();
            HxcNews news = hxcNewsServicePortType.find(1);
            System.out.println(news.getTitle());                    
        } catch (ServiceException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (RemoteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
}

我认为错误是由于find()类的HcxNewsService方法返回的xml输出所致。一些XML IS成功返回，并且它没有足够好地形成反序列化（从中构造一个对象）。

如堆栈跟踪中所述...... “encountered a child element, which is NOT expected, in something it was trying to deserialize”（SAXParser不理解XML意味着xml未正确形成）。

可能的调试选项是尝试直接从DAO获取xml绑定对象...记录它......

public class Dao<T> extends HibernateDaoSupport implements IDao<T> {

    public T find(String str,int id) {

        try {
            T t = (T) getHibernateTemplate().get(str, id);
            System.out.println.t.toString()); // OR...
            LOGGER.info(t.toString());
            return t;
        } cach (RuntimeException re) {         
            throw re;
        }

    }
}

如果失败，请在服务器中调用代码执行相同的方法...

public class HxcNewsService implements IHxcNewsService {    
    private IDao dao;   
    public void setDao(IDao dao) {
        this.dao = dao;
    }
    public HxcNews find(int id){
        // before returning, see what is database returning...
        LOGGER.log(dao.find("com.ews.bean.HxcNews",id));
        return (HxcNews) dao.find("com.ews.bean.HxcNews",id);
    }
}

让我们知道你最终如何解决它。

调用错误的客户端如下：org.xml.sax.SAXException：SimpleDeserializer遇到一个子元素，这是不期望的
