java - 轴 IllegalArgumentException 但 SOAP 消息是正确的

Question

我关注了client和 server创建一个简单的客户端-服务器计算器 Web 服务的教程，该服务执行两个 int 的简单加法。我所有的类都是由 Intelliji 自动生成的。

当我运行客户端时，我得到:

AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.generalException
 faultSubcode: 
 faultString: Tried to invoke method public int calculator.Calculator.add(int,int) with arguments java.lang.Integer,null.  The arguments do not match the signature.; nested exception is: 
    java.lang.IllegalArgumentException
 faultActor: 
 faultNode: 
 faultDetail: 
    {http://xml.apache.org/axis/}hostname:unknown

但是 SOAP 请求是正确的:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
      <a xmlns="http://calculator">1</a>
      <b xmlns="http://calculator">7</b>
   </soapenv:Body>
</soapenv:Envelope>

这是我的计算器类:

package calculator;

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

@WebService
public class Calculator {

    @WebMethod
    public int add(int a, int b) {
        return a + b;
    }

}

所有代码均由 Intelliji 内置函数生成，例如从 Java 代码生成 WSDL 和从 WSDL 生成 Java 代码。

这是客户端测试代码:

package calculator;

import javax.xml.rpc.ServiceException;
import java.rmi.RemoteException;

public class Test {

    public static void main(String[] args) {

        CalculatorService serviceLocator = new CalculatorServiceLocator();

        Calculator_PortType service = null;
        try {
            service = serviceLocator.getCalculator();
        } catch (ServiceException e) {
            e.printStackTrace();
            throw new RuntimeException("Something went wrong");
        }

        try {
            int add = service.add(1,7);
            System.out.println("add: " + add);

        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }
}

这是 WSDL:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://calculator" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://calculator" xmlns:intf="http://calculator" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

         </wsdl:input>
         <wsdl:output name="addResponse">
            <wsdlsoap:body use="literal"/>
         </wsdl:output>
      </wsdl:operation>
   </wsdl:binding>
   <wsdl:service name="CalculatorService">

SOAP 请求正确。我有一个运行良好的 Hello World 示例。一切似乎都是对的。我没有更改任何默认设置。

公开类 (1) 并生成 WSDL 文件 (2) 时，请确保使用 wrapped 样式而不是 document。
