Wildfly 27 服务器 - 简单的 JAX-WS 部署 - 部署/启动工作 - SOAP 调用导致错误“unmarshall 错误”

问：

我最近发布了一个问题，现在通过从 WildFly 23 升级到 27 解决了这个问题，其中部署了简单的 JAX-WS 端点，您可以在日志中看到启动，并且 WSDL URL 响应了预期的 WSDL。原始帖子与部署问题

现在，在解决了部署问题之后，我使用 POSTMAN 从 WildFly 托管的端点导入 WSDL。它加载正常，并且正确显示 2 个操作。

SOAP 消息从 POSTMAN 发送到服务器

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <getEmployee xmlns="http://ws.jaxws.example.com/">
      <arg0>100</arg0>
    </getEmployee>
  </soap:Body>
</soap:Envelope>

我得到以下带有错误的响应：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Client</faultcode>
            <faultstring>Unmarshalling Error: unexpected element (uri:"http://ws.jaxws.example.com/", local:"arg0"). Expected elements are &lt;{}arg0> </faultstring>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

WSDL：（来自已部署的服务）

“Employee”的 JAXB 注解类如下所示：

package com.example.jaxws.ws;

import jakarta.xml.bind.annotation.XmlRootElement;
import jakarta.xml.bind.annotation.XmlType;

@XmlRootElement(name = "Employee")
@XmlType()
public class Employee {

    private static final long serialVersionUID = 1L;
    private int id;

    private String name;

    public Employee() {
    }

    public Employee(int id, String name) {
        this.id = id;
        this.name = name;
    }

    public void setId(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Employee{" +
                "id=" + id +
                ", name='" + name + '\'' +
                '}';
    }

}

服务实现和接口如下所示：

package com.example.jaxws.ws;

import jakarta.jws.WebMethod;
import jakarta.jws.WebParam;
import jakarta.jws.WebResult;
import jakarta.jws.WebService;
import jakarta.jws.soap.SOAPBinding;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.ThreadContext;

import java.util.UUID;

@WebService(serviceName = "EmployeeService", endpointInterface = "com.example.jaxws.ws.EmployeeService")
@SOAPBinding(style= SOAPBinding.Style.DOCUMENT)
public class EmployeeServiceImpl implements EmployeeService {

    private static final Logger logger = LogManager.getLogger(EmployeeServiceImpl.class);

    @WebMethod
    @WebResult(name = "Employee")
    public Employee getEmployee(@WebParam(name = "id", targetNamespace = "http://ws.jaxws.example.com/") int id) {

        String txid = UUID.randomUUID().toString();
        ThreadContext.put("txid", txid);
        Employee employee = new Employee(id, "Smith");
        logger.info("Employee: [] returned", employee.toString());
        return null;

    }

    @WebMethod
    public Employee addEmployee(int id, String name) {
        return new Employee(id, name);
    }
}

接口：

package com.example.jaxws.ws;

import jakarta.jws.WebMethod;
import jakarta.jws.WebParam;
import jakarta.jws.WebService;
import jakarta.jws.soap.SOAPBinding;

@WebService
@SOAPBinding(style= SOAPBinding.Style.DOCUMENT)
public interface EmployeeService {

    @WebMethod
    public Employee getEmployee(@WebParam(name = "id", targetNamespace = "http://ws.jaxws.example.com/") int id);
    @WebMethod
    Employee addEmployee(int id, String name);
}

生成了 WSDL。我已经运行了 wsconsume 来查看它会为客户端调用生成哪些类（但我最终使用 POSTMAN 只是为了在服务端进行基本的测试调用）。

在代码生成过程中没有看到任何错误，我得到了一个装满代码的文件夹：

我试图理解为什么返回错误。
