【开发实践】Springboot3.4.0 Invalid bean definition with name ‘testMapper‘ defined in file

    今天使用最新的Springboot版本3.4.0进行技术验证，利用以前Springboot2.X的代码和依赖，升级了一下Springboot版本，启动发现以下问题：

Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

解决方法：

     原来springboot集成mybatis的版本是3.0.2，需要升级到3.0.3或3.0.4版本

	<dependency>
			<groupId>org.mybatis.spring.boot</groupId>
			<artifactId>mybatis-spring-boot-starter</artifactId>
			<version>3.0.4</version>
		</dependency>
