调用webservice中含返回值为自定义对象的方法时，报ClassCastException错误

本人初学webservice，平台用spring+cxf+ibatis，在调用接口中含返回自定义对象的方法时，就会报ClassCastException，即方法：

public List<User> getUserList()

调用返回值为基本类型的方法，则没问题，如：

public Integer getUserCount();

困扰很久，包括调用含自定义类型的方法，也会报同样错误，如：

public void bImportData(List<User> uList);

请教各位大牛，盼回复，谢啦~\(≧▽≦)/~

 

1、服务端Webservice接口

@WebService
public interface ICxfDemo {
       /**
	 * 获取用户数量
	 * @return
	 */
	@WebMethod(operationName = "getUserCount", action = "urn:GetUserCount")
	public Integer getUserCount();


	/**
	 * 获取用户列表
	 * @return
	 */
	@WebMethod(operationName = "getUserList", action = "urn:GetUserList")
	public List<User> getUserList();
}

 

2、服务端webservice接口实现类：

@WebService(endpointInterface = "com.ocrlp.serv.ws.ICxfDemo",serviceName = "CxfDemoImpl") 
public class CxfDemoImpl implements ICxfDemo {
	
        private ServiceManager servMgr;
	@Resource(name="servMgr") 
	public void setServMgr(ServiceManager servMgr) {
		this.servMgr = servMgr;
	}
	
       /**
	 * 获取用户数量
	 * @return
	 */
	@Override
	public Integer getUserCount() {
		return servMgr.getUserRowCount();
	}

	/**
	 * 获取用户列表
	 * @return
	 */
	@Override
	public List<User> getUserList() {
		return servMgr.listAll_Users();
	}
}

 

3、beans.xml

    <jaxws:endpoint id="cxfDemo" 
        implementor="com.ocrlp.serv.ws.CxfDemoImpl" address="/cxfDemo" />

 
4、客户端java调用测试代码：

public class ICxfDemoTest {
	
	private ICxfDemoTest() {}
	private static ICxfDemo dsServ;
	
	/**
	 * 初始化构造方法
	 * @return
	 */
	synchronized public static ICxfDemo init() {
		if (dsServ == null) {
			JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
			factory.setServiceClass(ICxfDemo.class); // 注册WebService接口
			factory.setAddress("http://127.0.0.1/web/webservice/cxfDemo"); // 设置WebService地址
			dsServ = (ICxfDemo)factory.create(); 
		}
		return dsServ;
	}

	public Integer getUserCount() {
		return dsServ.getUserCount();
	}
	
	public static void main(String[] args) {
		System.out.println("客户端调用结果:" + ICxfDemoTest.init().getUserCount());
	}
}

 

5、实体类是可序列化的

public class User implements Serializable {
	
	private static final long serialVersionUID = 2519452507329194492L;
	private String uid;
	private String username;
	private String password;
	private String realname;
	private String org;
	private String job;

	//getter , setter 省略

}

 

6、运行eclipse服务器测试报错：
