jersey - 使用 Jersey 构建 REST 服务

Question

我正在尝试将我的 REST Web 服务从 1.17.1 升级到 1.19，而且我正在努力让构建正确无误。在不更改任何源的情况下，服务不会每次都出现多个错误消息。

这是我项目的pom.xml

这是我启动 Web 服务时的错误。

javax.servlet.ServletException: Servlet CcxAPIs 的 Servlet.init() 抛出异常 org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:474) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java: 79) org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:624) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:349) org.apache.coyote.http11.Http11Processor.service( Http11Processor.java:783) org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:789) org.apache.tomcat.util.net。 NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1437) org.apache.tomcat.util.net。SocketProcessorBase.run(SocketProcessorBase.java:49) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) org.apache.tomcat。 util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) java.lang.Thread.run(Thread.java:748)

根本原因
com.sun.jersey.api.container.ContainerException：ResourceConfig 实例不包含任何根资源类。com.sun.jersey.server.impl.application.RootResourceUriRules.(RootResourceUriRules.java:99) com.sun.jersey.server.impl.application.WebApplicationImpl._initiate(WebApplicationImpl.java:1359) com.sun.jersey.server .impl.application.WebApplicationImpl.access$700(WebApplicationImpl.java:180) com.sun.jersey.server.impl.application.WebApplicationImpl$13.f(WebApplicationImpl.java:799) com.sun.jersey.server.impl.application .WebApplicationImpl$13.f(WebApplicationImpl.java:795) com.sun.jersey.spi.inject.Errors.processWithErrors(Errors.java:193) com.sun.jersey.server.impl.application.WebApplicationImpl.initiate(WebApplicationImpl. java:795) com.sun.jersey。

我在这里错过了什么吗？我相信很多人都应该面对这些问题。请帮助提出解决此问题的建议。
