我使用 com.sun.jersey.spi.spring.container.servlet.SpringServlet 创建了两个 Jersey servlet 项目。我使用 Jersey 1.19.1 jar 。这两个项目的 lib 文件夹中都有依赖的 jar。我将这两个项目部署在 liberty 9 服务器中。
当我尝试访问端点时，一个项目工作正常，但另一个项目工作正常。如果第二个项目不起作用，我在控制台中出现以下异常。如果我单独重新启动该项目(而不是服务器)，它就可以工作。我不知道为什么，我尝试找到永久解决方案。
SRVE0271E: Uncaught init() exception created by servlet [jersey-servlet] in application [secondproject]: java.lang.RuntimeException: javax.naming.NameNotFoundException: CDIExtension
SRVE0315E: An exception occurred: java.lang.Throwable: javax.servlet.ServletException: SRVE0207E: Uncaught initialization exception created by servlet
如果第一个项目不起作用，我会在控制台中看到以下异常。
SRVE0271E:应用程序 [firstproject] 中的 servlet [jersey-servlet] 创建的未捕获 init() 异常:java.lang.ClassCastException:com.sun.jersey.server.impl.cdi.CDIExtension 与 com.sun.jersey 不兼容.server.impl.cdi.CDIExtension
SRVE0276E:初始化 Servlet [jersey-servlet] 时出错:javax.servlet.ServletException:SRVE0207E:Servlet 创建的未捕获初始化异常

最佳答案
请查看this link ，这对我很有帮助。
设置system-property即可解决问题
com.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true
这可以通过 GlassFish 服务器控制台完成。
- 选择节点 -> 配置 -> 服务器配置 -> JVM 设置 更改为“JVM 选项”选项卡
添加新条目
-Dcom.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true
重新启动服务器
