I had this error when I was importing via @import a class that wasn't deployed on the server. Unfortunatly, the stack doesn't tell you what class is missing, but you can figure it out with removing them one by one and restart your app.

当我通过@import 导入一个没有部署在服务器上的类时，我遇到了这个错误。不幸的是，堆栈并没有告诉您缺少哪个类，但是您可以通过将它们一一删除并重新启动应用程序来弄清楚。

Now, why wouldn't the class be deployed on the server if the project actually compiles?

现在，如果项目实际编译，为什么不将类部署在服务器上？

EDIT: I found out I had the problem when the import is using a class that is on the classpath via a Maven dependency. I also had this dependency (the project) checked out in Eclipse. In this case, it seems Eclipse will deploy the project checked out instead of the build from the repository. It won't look at the external dependency of this project.

编辑：我发现当导入通过 Maven 依赖项使用类路径上的类时我遇到了问题。我还在 Eclipse 中检出了这个依赖项（项目）。在这种情况下，Eclipse 似乎将部署签出的项目，而不是从存储库中构建。它不会查看这个项目的外部依赖。

The solution: Close all external dependency projects in Eclipse to make sure that you actually deploy the version from Maven repository.

解决方案：关闭 Eclipse 中的所有外部依赖项目，以确保您实际部署了来自 Maven 存储库的版本。

You might be missing

你可能错过了

<context:component-scan base-package="org.example">

in your applicationContext.xml file OR

在您的 applicationContext.xml 文件中或

@ComponentScan("com.example") 

annotation if you are doing code based configuration.

如果您正在进行基于代码的配置，则注释。

I had old versions of spring libraries in my WEB-INF/lib. I deleted everything in lib folder and tried building and publishing. It worked.

我的 WEB-INF/lib 中有旧版本的 spring 库。我删除了 lib 文件夹中的所有内容并尝试构建和发布。有效。

Thanks.

谢谢。

Judging from the stacktrace you are mixing different versions of Spring. java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotationUtils.isInJavaLangAnnotationPackage(Ljava/lang/annotation/Annotation;)is the indicator for that.

从堆栈跟踪来看，您正在混合不同版本的 Spring。java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotationUtils.isInJavaLangAnnotationPackage(Ljava/lang/annotation/Annotation;)是指标。

Check your dependencies and make sure that you don't pull in conflicting versions.

检查您的依赖项并确保您没有引入冲突的版本。

General rule of thumb, never mix jars of different versions of a framework (in this case Spring but same applies to for instance Hibernate).

一般的经验法则，永远不要混合框架的不同版本的 jar（在这种情况下是 Spring，但同样适用于例如 Hibernate）。
