Weblogic - JAX-RS 应用程序中断 JAX-RS 库引用
Weblogic - JAX-RS Application breaks upon JAX-RS library reference
我的一些 REST 应用程序有问题，当我在它们的 weblogic.xml 配置文件中引用 Jax-rs 时，其中一些会中断，而另一些则不会。这真是奇怪。
在 Weblogic.xml 文件中，我有这个：
<library-ref>
<library-name>jax-rs</library-name>
<specification-version>2.0</specification-version>
</library-ref>
并且 Jax-RS 库安装在我的 weblogic 中。
引用此内容后，当我尝试在浏览器上 运行 GET 请求时，我看到一条 "request failed" 消息。
在日志中，我看到了这个：

我一直在努力找出问题所在，但一无所获。
我正在尝试实现 CORS 过滤器，如果不引用 Jax-rs 库，它将无法工作。
求求你帮忙！
我当时使用的weblogic需要升级。虽然，我会建议任何对构建 REST 服务感兴趣的人切换到 Spring Boot。它比在 Weblogic 上托管 JAX-RS web-service 项目更轻量，也更容易处理。
我的一些 REST 应用程序有问题，当我在它们的 weblogic.xml 配置文件中引用 Jax-rs 时，其中一些会中断，而另一些则不会。这真是奇怪。
