我正在尝试使用 JAX-WS 制作一个简单的项目。我遵循这个例子：https://docs.oracle.com/javaee/7/JEETT.pdf 准确地说是关于 JAX-WS 的头。我已经遵循了所有步骤。不同之处在于我使用 wildfly 作为服务器和 IDE Eclipse，这很重要，因为我必须从命令提示符生成HelloService。网络服务的代码：
@WebService
public class Hello {
private final String message = "Hello, ";
public Hello() {
}
@WebMethod
public String sayHelloName(String name) {
return message + name + ".";
}
@WebMethod
public String sayHello() {
return message + ".";
}
}
和 servlet 的代码：
@WebServlet(name = "HelloServlet", urlPatterns = { "/HelloServlet" })
public class HelloServlet extends HttpServlet {
private static final long serialVersionUID = 1530081955969170723L;
@WebServiceRef(wsdlLocation = "http://localhost:8080/SampleRest-web/Hello?wsdl")
private HelloService service;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
out.println("<html lang="en">");
out.println("<head>");
out.println("<title>Servlet HelloServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet HelloServlet at " + request.getContextPath() + "</h1>");
out.println("<p>" + sayHello("world") + "</p>");
out.println("</body>");
out.println("</html>");
}
}
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
try {
processRequest(request, response);
} catch (ServletException e) {
e.printStackTrace();
}
System.out.println("Test2");
}
private String sayHello(java.lang.String arg0) {
try {
Hello port = service.getHelloPort();
return port.sayHelloName(arg0);
}catch (Exception e) {
e.printStackTrace();
}
return "Ne stana";
}
}
带有 ？wsdl 的 url 代码工作正常，它会生成 wsdl 代码。当我调用servlet时，这是我得到的错误：

我再次设法自己找到了解决方案。问题出在客户端。执行命令时：wsimport ，创建了一个类包，其中它们的
@XmlType(name = "SayHelloName", propOrder = {
"arg0"
})
不行。这个名字是小首字母，导致例外。一旦我改变了它，它就开始工作了。希望这个答案对其他初学者使用 JAX-WS 有所帮助
