As you may or may not already see in the title, I try to figure out how to use spring data in my library and how to use this library in my other projects. (all not web-based applications just to clarify)
正如您可能已经或可能未在标题中看到的那样,我试图弄清楚如何在我的库中使用spring数据以及如何在我的其他项目中使用此库。 (所有不是基于网络的应用程序只是为了澄清)
I am trying to answer for several days for this problem, maybe I am just looking wrong, I am a total beginner as far as spring is concerned.
我试图回答这个问题几天,也许我只是看错了,就春天而言,我是一个初学者。
It only shows errors on startup.

This kind of exception is a sure sign that you have incompatible versions of you dependencies:
这种异常肯定表明您具有不兼容的依赖项版本:
Caused by: java.lang.NoSuchMethodError: org.springframework.aop.framework.AopProxyUtils.getSingletonTarget(Ljava/lang/Object;)Ljava/lang/Object; at
Use mvn dependency:tree -Dverbose to see the versions of dependencies of your projects. Including conflicts (see https://maven.apache.org/plugins/maven-dependency-plugin/examples/resolving-conflicts-using-the-dependency-tree.html for an example).
使用mvn dependency:tree -Dverbose查看项目依赖项的版本。包括冲突(有关示例,请参阅https://maven.apache.org/plugins/maven-dependency-plugin/examples/resolving-conflicts-using-the-dependency-tree.html)。
Only use non-conflicting versions.
仅使用非冲突版本。
