使用Apache CXF的JAXWS Web服务 - 名称""对于JDOM/XML名称空间不合法:名称空间URI必须是非null且非空字符串

Question

我正在使用Apache CXF(2.7.14)使用Code First方法和注释开发JAXWS Webservice.我用JAXWS注释注释了SEI,SEI实现类,用JAXB注释注释了域对象.每当尝试使用eclipse生成WSDL时,我都会收到以下错误:

IWAB0014E Unexpected exception occurred.
  The name "" is not legal for JDOM/XML namespaces: Namespace URIs must be non-null and non-empty Strings.
      org.jdom.IllegalNameException: The name "" is not legal for JDOM/XML namespaces: Namespace URIs must be non-null and non-empty Strings.

员工服务类是:

@WebService
@SOAPBinding(style = Style.DOCUMENT, use = Use.LITERAL, parameterStyle = ParameterStyle.WRAPPED)
@WebFault(name = "exception", faultBean = "java.lang.Exception")
public interface EmployeeService
{
    @WebMethod(exclude = false)
    @RequestWrapper(className = "home.cxfwebservicesdemo.employeeservice.domain.Employee")
    @Oneway
    public void addEmployee(@WebParam(name = "employee", mode = Mode.IN) Employee employee) throws Exception;

    @WebMethod(exclude = false)
    @RequestWrapper(className = "home.cxfwebservicesdemo.employeeservice.domain.Employee")
    @Oneway
    public void updateEmployee(@WebParam(name = "employee", mode = Mode.IN) Employee employee) throws Exception;

    @WebMethod(exclude = false)
    @Oneway
    public void deleteEmployee(@WebParam(name = "employeeId", mode = Mode.IN) long employeeId) throws Exception;

    @WebMethod(exclude = false)
    @ResponseWrapper(className = "home.cxfwebservicesdemo.employeeservice.domain.Employee")
    @WebResult(name = "employee")
    public Employee getEmployeeById(@WebParam(name = "employeeId", mode = Mode.IN) long employeeId) throws Exception;

    /*
     * @WebMethod(exclude = false)
     * @ResponseWrapper(className = "java.util.ArrayList")
     * @WebResult(name = "employeeList") public List<Employee> getAllEmployees() throws Exception;
     */
}

我没有广泛地从事过Web服务.

如果您需要更多详细信息,请与我们联系.

有人可以帮我找到上述问题的解决方案吗？

谢谢!

在使用CXF Web服务时,我在使用向导生成Web Service时遇到了类似的错误.为解决此问题,我将namespace属性值添加到@WebService注释中

@WebService(targetNamespace="http://www.benjmaz.com")
public class MyWebService{
   @Resource
   private WebServiceContext context;
}

提供您选择的其他名称(尤其是您公司的域名)作为targetnamespace
