jax-rs tomcat maven原始服务器未找到目标资源的当前表示，或不愿意透露存在

Question

我使用JAX-RS。我有一个Maven项目和Tomcat服务器。我用路径/ books java类。我也使用jersey 1.x。在Tomcat控制台中，我可以看到我的应用程序已部署。

网址http://localhost:8080/rest-server可以正常工作，但是当我执行网址时

http://localhost:8080/rest-server/books

我得到了错误

HTTP 404



The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

这是我的web.xml文件

在我定义的web.xml中

<url-pattern>/rest-server/*</url-pattern>
