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