我在pom文件里引入了 commons-dbcp2、commons-pool2 的 maven 依赖,然后在 spring 配置文件里注册了 org.apache.commons.dbcp2.BasicDataSource 作为 dataSource bean,但是 spring 启动的时候报异常了,日志如下:

上述4个 mapper,是使用配置的方式注册的,因为我使用注解扫包的话,无法自动注入这些 mapper,不知道为啥……

不知道出现这个异常的原因是不是依赖包有冲突才导致的,求大神指教,万分感谢!

Le problème a été résolu, merci à mes collègues pour leur aide.
Il y a un problème avec le fichier pom de mon projet. Le contenu de la balise <packing> est pom. Dans ce cas, aucun package ne sera généré lors du packaging du projet (le module parent utilise généralement la valeur pom. ), alors je l'ai changé en guerre. En fait, cette valeur par défaut est jar, mais je ne l'ai jamais modifiée, et elle s'est transformée en pom inexplicablement...

Vérifiez s'il existe le package jar dans le répertoire lib, et si c'est le cas, vérifiez s'il existe différentes versions du package jar.
