只配置Mysql相关依赖包的时候可以使用@Teansactional但是会报错，具体原因根据我实际使用情况是一下原因：
需要依赖AOP的aspect包

        <dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-aspects</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-orm</artifactId>
		</dependency>
