Web服务：prolog中意外的EOF - 当我使用Apache CXF和具有POJO参数的方法时，我得到了这个

Question

我有以下登录服务界面：

@Path("/loginService/")
@WebService(serviceName = "LoginService", name = "LoginService", targetNamespace = "http://ws.test.com")
public interface LoginService {
    /**
     * Takes an authentication request, and returns an authentication response.
     * In the event of an authentication failure, an HTTP status of 401 should
     * be returned.
     * 
     * @param request
     * @return
     */
    @WebMethod
    @GET
    @Path("/")  
    public AuthenticationResponse login(@WebParam(name = "request") final AuthenticationRequest request);
}

我的春季档案中有以下内容

<bean id="loginService" autowire="autodetect"
    class="com.test.mobile.webservices.authentication.LoginServiceImpl">
</bean>



<jaxws:endpoint id="LoginServiceEndpoint"
                serviceName="LoginService"
                implementorClass="com.test.mobile.webservices.authentication.LoginService"
                implementor="#loginService"
                address="/loginService">
    <jaxws:serviceFactory>
        <ref bean="jaxws-and-aegis-service-factory"/>
    </jaxws:serviceFactory>
</jaxws:endpoint>

当我尝试点击以下网址时：

http://localhost:8080/TPCMobileWS/api/rest/loginService?wsdl

我收到以下消息：

  

发生JAXBException：在[row，col。的prolog中意外的EOF   {unknown-source}]：[1,0]。意外的EOF在prolog的[row，col   {unknown-source}]：[1,0]。

如果我在登录方法中完全删除了“request”参数，那么上面的URL就可以了......没有错误，显示正确的数据。

传递POJO时我做错了什么？它只有几个原始类型，包括getter和setter。我错过了一些注释吗？

非常感谢您的帮助！

以下是身份验证请求：

package com.test.mobile.webservices.authentication;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlRootElement;

import com.test.mobile.webservices.Localization;

@XmlRootElement
public class AuthenticationRequest implements Serializable {

    private static final long serialVersionUID = 1L;

    private String username;
    private Localization.Country country;
    private String password;

    public AuthenticationRequest() {

    }

    /**
     * For now, this is the consultant's ID.
     * 
     * @return
     */
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    /**
     * The country that the consultant is associated with, as a two letter ISO
     * country code.
     * 
     * @return
     */
    public Localization.Country getCountryCode() {
        return country;
    }

    public void setCountryCode(Localization.Country country) {
        this.country = country;
    }

    /**
     * The consultant's password.
     * 
     * @return
     */
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}
