如何修复 Java Jersey 中的 ClassNotFound 异常？

Question

我现在尝试设置一个简单的 Rest 服务，但我总是遇到同样的错误。

我正在使用 Tomcat 8.5 和 JDK-11.0.3 以及我的 IDE Eclipse

错误：

SEVERE: Servlet [Jersey Web Application] in web application [/CrunchifyRestJerseyExample] threw load() exception java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer at org.apache.catalina.loader.WebappClassLoaderBase. loadClass(WebappClassLoaderBase.java:1415) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1223) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:533) at org.apache .catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:514) 在 org.ZB6EFD606D118D0F 62066E31419FF04CCZ.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:149) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1071) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper. java:1011) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4952) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5266) at org.apache.catalina.util .LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1427) at org.ZB6EFD606D118D0F62066E31419FF0 4CCZ.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1417) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.
