java.lang.NoSuchMethodError: org.apache.tomcat.util.res.StringManager.getManager 与 Spring hetos 中的 tomcat

Question

我正在尝试创建一个 Spring hateos 的示例应用程序并遇到以下异常：

java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/hetos-medias]]

看起来org.apache.tomcat.util.res.StringManager.getManager 类可能有重复的 jar，但我在类路径中没有找到任何重复的 jar。我使用的是 tomcat 7，以下是我的 pom.xml 和库详细信息。

您必须在 pom.xml 中设置以下内容

<tomcat.version>7.0.59</tomcat.version>
