Spring Boot中不需要加 @EnableTransactionManagement 來開啓事務

~/org/springframework/boot/spring-boot-autoconfigure/2.3.0.RELEASE/spring-boot-autoconfigure-2.3.0.RELEASE.jar!/META-INF/spring.factories

# Auto Configure
org.springframework.boot.autoconfigure.transaction.TransactionAutoConfiguration,\

/**
 * Auto-configuration for Spring transaction.
 */
@Configuration(proxyBeanMethods = false)
@ConditionalOnClass(PlatformTransactionManager.class)
@AutoConfigureAfter({JtaAutoConfiguration.class, HibernateJpaAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, Neo4jDataAutoConfiguration.class})
@EnableConfigurationProperties(TransactionProperties.class)
public class TransactionAutoConfiguration {
    //...
    @Configuration(proxyBeanMethods = false)
    @ConditionalOnBean(TransactionManager.class)
    @ConditionalOnMissingBean(AbstractTransactionManagementConfiguration.class)
    public static class EnableTransactionManagementConfiguration {
        @Configuration(proxyBeanMethods = false)
        @EnableTransactionManagement(proxyTargetClass = false) //這裏其實以及加了
        @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "false", matchIfMissing = false)
        public static class JdkDynamicAutoProxyConfiguration {}
        @Configuration(proxyBeanMethods = false)
        @EnableTransactionManagement(proxyTargetClass = true)  //這裏其實以及加了
        @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "true", matchIfMissing = true)
        public static class CglibAutoProxyConfiguration {}
    }
}

同理不需要加 @EnableAspectJAutoProxy 來開啓aop

@Configuration(proxyBeanMethods = false)
@ConditionalOnProperty(prefix = "spring.aop", name = "auto", havingValue = "true", matchIfMissing = true)
public class AopAutoConfiguration {
    @Configuration(proxyBeanMethods = false)
    @ConditionalOnClass(Advice.class)
    static class AspectJAutoProxyingConfiguration {
        @Configuration(proxyBeanMethods = false)
        @EnableAspectJAutoProxy(proxyTargetClass = false)
        @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "false", matchIfMissing = false)
        static class JdkDynamicAutoProxyConfiguration {}
        @Configuration(proxyBeanMethods = false)
        @EnableAspectJAutoProxy(proxyTargetClass = true)
        @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "true", matchIfMissing = true)
        static class CglibAutoProxyConfiguration {}
    }
}
