使用wsdl的java JAXWS问题

2 年，1 月 Questions & Answers

我正在尝试使用JAX-WS创建一个简单的项目。我遵循这个示例：https://docs.oracle.com/javaee/7/JEETT.pdf准确地说是关于JAX-WS的头部。我已经完成了所有步骤。区别在于，我使用wildfly作为服务器和ideeclipse，这很重要，因为我必须从命令提示符生成HelloService。Web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 + ".";
        }

    }

以及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";

    }
}

url代码与？wsdl工作正常，它生成wsdl代码。当我调用servlet时，我得到的错误是：

    我又一次设法自己找到了解决办法。问题出在客户端。在执行命令：wsimport时，创建了一组类，并在其中创建了它们的

     @XmlType(name = "SayHelloName", propOrder = {
    "arg0"
})

    不好。这个名字的首字母很小，这导致了这个例外。我一换它，它就开始工作了。希望这个答案能帮助其他JAX-WS初学者
