java - 在 CXF 休息服务中找不到类资源

Question

我正在尝试使用 apache cxf 实现 restfull webservice。

在 tomcat 中部署 war 文件时出现以下错误:创建名称为“Analysis”的 bean 时出错:初始化方法调用失败；嵌套异常是 org.apache.cxf.service.factory.ServiceConstructionException

INFO: Loading XML bean definitions from ServletContext resource [/WEB-INF/cxf.xml]

下面是cxf.xml:

<beans default-autowire="byName" xmlns="http://www.springframework.org/schema/beans"

   </jaxrs:extensionMappings>
  </jaxrs:server>
    <bean class="com.bt.ws.pointsystem.pojo.AnalysisResponse" id="AnalysisResponse">
    </bean>
</beans>

web.xml:

  <servlet-mapping>

   <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
 </web-app>

类定义:

package com.bt.ws.pointsystem.pojo;

public class AnalysisResponse {
    private String UserId;
    private String AnalysisType;
    public String getUserId() {
        return UserId;
    }
    public void setUserId(String userId) {
        UserId = userId;
    }
    public String getAnalysisType() {
        return AnalysisType;
    }
    public void setAnalysisType(String analysisType) {
        AnalysisType = analysisType;
    }





}

我还缺少什么？

TIA

此问题的另一个常见原因是使用@Path protected 而非public 注释方法。
