发现Java模型和WSDL模型之间存在Soap不匹配

我正在用Java开发SOAP服务，但遇到以下错误：

WARNING: Mismatch between Java model and WSDL model found, For wsdl operation 
{http://database.unitn.it/}isLoginOkay,There is no matching wsdl fault with detail 
QName {http://interfaces.database.unitn.it/}Exception

我正在使用Java1.8，所有东西都在本地主机上运行。这台机器运转良好。 我不知道问题出在哪里。我尝试了很多方法来解决这个问题，但是我没有四个没有一个线程来讨论这个问题。 请帮忙

编辑：

以下是出版商：

private static final String mUrl = "http://localhost:" + Ports.MASTER_DATABASE_SERVICE + "/database";

public static void launch() throws Exception
{
    System.out.println("----Starting on ..." + mUrl);
    Endpoint.publish(mUrl, new Database());
    System.out.println("----SOAP Service started!!!!");
}

这里是客户端部分的接口：

@WebService
@SOAPBinding(style = Style.RPC)
public interface DatabaseAPIsInterface
{

    @WebMethod
    public User isLoginOkay(String password, String email) throws Exception;

}

    String mUrl = "http://localhost:" + Ports.MASTER_DATABASE_SERVICE + "/database?wsdl";
    URL url = new URL(mUrl);
    QName qname = new QName("http://database.unitn.it/", "DatabaseService");
    Service service = Service.create(url, qname);
    DatabaseInterface database = service.getPort(new QName("http://database.unitn.it/", "DatabasePort"), DatabaseAPIsInterface.class);
    User user = database.isLoginOkay(password, email);
    System.out.println(user);

这里是该方法的实现isLoginOkay

myMethod的throws子句是否与.wsdl文档中相应的中指定的错误完全匹配？此外，您可能希望坚持使用Java 1.7，直到1.8已经过测试版，并且在首次公开发布后至少有一次小版本更新，除非您确实需要1.8语言功能。您是否可以将您的发布者类从wsdl的实现和服务部分粘贴到此处。如果可能，我希望使用Java 1.8。还有一件事，我在这里用IntelliJIEACheck来回答：

    String mUrl = "http://localhost:" + Ports.MASTER_DATABASE_SERVICE + "/database?wsdl";
    URL url = new URL(mUrl);
    QName qname = new QName("http://database.unitn.it/", "DatabaseService");
    Service service = Service.create(url, qname);
    DatabaseInterface database = service.getPort(new QName("http://database.unitn.it/", "DatabasePort"), DatabaseAPIsInterface.class);
    User user = database.isLoginOkay(password, email);
    System.out.println(user);
