我正在学习如何使用 Spring Boot。我正在尝试将我的应用程序与数据库连接，但我不完全确定为什么会收到此错误以及如何修复它。我在网上找不到任何东西。请帮我。如果您需要更多信息，请询问我，我会尽我所能。

我正在学习本教程（西班牙语）：https://www.youtube.com/watch?v=7vHzVN0EiQc 我卡在 2:23 分钟了
当我知道真正的错误原因时，我会更新标题以帮助遇到同样问题的人:)
我尝试将此行添加到 application.properties
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
#JPA/Hibernate
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
#Transactions
spring.jpa.properties.hibernate.transaction.manager_lookup_class=org.hibernate.transaction.JBossTransactionManagerLookup
我还检查了资源文件夹是否已正确标记（确实如此）。
正如您所指出的，问题出在自动配置中，但由于您要使用的版本，您会在
spring-boot这里你必须改变
来自
2.6.3类似这样的：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>3.2.0</version>
</dependency>
因为你的情况下父版本是
3.2.0 <parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.2.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
我认为最好的方法是如果该依赖项由 Spring 管理，则不要在
pom.xml这意味着你必须删除所有
versiongroupId<groupId>org.springframework.boot</groupId>
正如我上面提到的，不要混合使用框架版本，这就是为什么你应该避免它从 2.x 到 3.x 的变化
我已经修好了！通过使用 IntelliJ Idea，我找到了包含 “platformTransactionManagerCustomizers” :
的依赖项<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.6.3</version>
</dependency>
