我正在尝试使用cxf rest公开rest服务。我有cxf 2.7.5和spring 3.1.3.RELEASE，当尝试使用url http://localhost:8080/web/services/rest/getreq时，它会出现错误。

我创建了服务类**@service（“dimRequirementManager”）**，那么是否有必要在cxf-servlet.xml中创建bean？

cxf-servlet.xml文件

    </jaxrs:server>

我不知道有什么样的冲突...
您可以尝试删除cxf-rt-ws-policy-3.1.1.jar。
我不知道为什么，但这对我很有效。
