我尝试将项目从 JDK8 升级到 JDK11，整个业务逻辑部分运行良好，但是当 Maven 到达测试类时，所有这些都失败并出现完全相同的异常\n例如

 initializationError(com.foo.bar.etc.utils.TimeUtilsTest)  Time elapsed: 0 sec  <<< ERROR!\njava.lang.NoSuchMethodError: 'void org.springframework.util.Assert.state(boolean, java.util.function.Supplier)'\n        at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.ensureSpringRulesAreNotPresent(SpringJUnit4ClassRunner.java:120)\n        at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<init>(SpringJUnit4ClassRunner.java:141)\n        at org.springframework.test.context.junit4.SpringRunner.<init>(SpringRunner.java:49)\n        at jdk.internal.reflect.GeneratedConstructorAccessor6.newInstance(Unknown Source)\n        at java.base/jdk.internal.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)\n        at java.base/java.lang.reflect.Constructor.newInstance(Constructor.java:490)\n        at org.junit.internal.builders.AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:104)\n        at org.junit.internal.builders.AnnotatedBuilder.runnerForClass(AnnotatedBuilder.java:86)\n        at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59)\n        at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:26)\n        at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59)\n        at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:33)\n        at org.apache.maven.surefire.junit4.JUnit4Provider.execute(JUnit4Provider.java:283)\n        at org.apache.maven.surefire.junit4.JUnit4Provider.executeWithRerun(JUnit4Provider.java:173)\n        at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:153)\n        at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:128)\n        at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:203)\n        at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:155)\n        at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:103)\n

一旦一切完成，它只是用列表总结所有测试类

Tests in error:\n  BaseSpringTest.initializationError \xc2\xbb NoSuchMethod 'void org.springframework.ut...\n  EmailAttachmentDaoImplTest.initializationError \xc2\xbb NoSuchMethod 'void org.spring...\n  EmailEventDaoImplTest.initializationError \xc2\xbb NoSuchMethod 'void org.springframe...\n  EmailMappingDaoImplTest.initializationError \xc2\xbb NoSuchMethod …

当使用我的 Eclipse 的 Tomcat9 服务器（v9.0.62）时，我的“应用程序”运行正常。然而，一旦部署到我的生产服务器上（v9.0.43），就会返回 404。Tomcat 没有记录任何堆栈跟踪。

两台服务器都使用 OpenJDK17 作为 JDK。使用 Spring < 6 版本时不会出现此问题。

Eclipse 控制台输出：

我正在尝试创建一个简单的 Spring MVC 来查看 main-menu.jsp 但我遇到了问题，而且我不知道如何修复它。我正在使用 Intellij 并通过 Maven 创建项目。

这是我的项目结构

src
  - main 
      - java 
        - com.example.mvc
           - HomeController.java
      -resources
  - webapp
      - WEB-INF
        - view 
            - main-menu.jsp
        - applicationContext.xml
        - web.xml

我的 pom.xml
