Question

您好我是Web Services的新手，我有Code First Approach的要求，

我有一个如下界面

package in.co.way2learn;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService(name="SQS",portName="SQSP",serviceName="SQSS") 
public interface StockQuoteService {

@WebMethod(operationName="getPrice")
public double getPrice(@WebParam(name="symbol")String symbol);

@WebMethod(operationName="aaa",action="aaaAction")
public boolean update(@WebParam(name="sybmol")String symbol,@WebParam(name="price")double price);

@WebMethod(operationName="bbb",action="bbbAction")
public boolean update(@WebParam(name="sybmol")String symbol,@WebParam(name="price")double price,@WebParam(name="flag")boolean flag);

}

如果将上述接口作为Web服务，我想公开一个实现。

实施类如下：

package in.co.way2learn;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(name="SQSI",
endpointInterface="in.co.way2learn.StockQuoteService",
portName="SQSIP",serviceName="SQSIS")
public class StockQuoteServiceImpl implements StockQuoteService{
@Override
public double getPrice(String symbol) {
    System.out.println("StockQuoteServiceImpl.getPrice()");
    return 123;
}
@Override
@WebMethod(operationName="aaa",action="aaaAction")
public boolean update(String symbol, double price) {
    System.out.println("StockQuoteServiceImpl.update()");
    return true;
}

@Override
@WebMethod(operationName="bbb",action="bbbAction")
public boolean update(String symbol, double price, boolean flag) {
    System.out.println("StockQuoteServiceImpl.update()");
    return true;
}
}

要将此服务公开为Web服务，我使用的是JDK的EndPoint类，如下所示。

package in.co.way2learn;

import javax.xml.ws.Endpoint;

public class Server {
public static void main(String[] args) {

    StockQuoteService stockQuoteService=new StockQuoteServiceImpl();
    String address="http://localhost:8080/sqs";
    Endpoint.publish(address, stockQuoteService);
    System.out.println("Server started..!");

} 
}

但是当我运行服务器程序时，我得到以下异常。

Exception in thread "main" javax.xml.ws.WebServiceException: class in.co.way2learn.jaxws.Update do not have a property of the name flag

在StockQuoteService接口和相应的实现中，我有两个重载update方法，一个是两个参数，而另一个是三个。

如果我将第二个update方法名称更改为其他名称，那么服务器运行正常，毫无例外。

但是当我仅重载update方法时会出现异常。

即使我保留了重载方法，它们的操作名称和相应的soap操作也不同，您可以在方法之上的注释中看到它们。

任何帮助都会让我感到非常欣慰和欣赏。
