1. 先找到这个注解：

![format_png][]  
2. 会自动加载这个类

![format_png 1][]  
3. 默认为mode = PROXY, 进入这个类

![format_png 2][]  
4. ProxyTransactionManagementConfiguration 类

![format_png 3][]  
5. 看TransactionInterceptor 类

![format_png 4][]  
6. invokeWithinTransaction 方法

![format_png 5][]  
7. 发现没有找到注入的类

![format_png 6][]  
8. 找到父类

![format_png 7][]  
9. 找到实现方法

![format_png 8][]  
10. 看到对目标方法是public的校验

![format_png 9][]  
11. 得出结果，为什么@Transactional加在private上无效

![format_png 10][]  
12. 再深入看AbstractFallbackTransactionAttributeSource 类可以知道@Transactional的注解解析器是：SpringTransactionAnnotationParser

![format_png 11][]
