SpringBoot集成Mybatis 时开启事务

1、首先在启动类加上

@EnableTransactionManagement(proxyTargetClass = true) 

注：proxyTargetClass默认为false，springboot的事务是以 JDK dynamic proxy 实现的。我不加之前启动报错

Action:

Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.

2、启动类中加上以下代码，注入 DataSourceTransactionManager 实例

@Bean
public PlatformTransactionManager txManager(DataSource dataSource) {
    return new DataSourceTransactionManager(dataSource);
}
