How @Transactional works ? Transactional propagation explained ! Transaction Management #springboot

In this lesson we will learn about the Transactional propagation levels. As we have a strong foundation on Transaction Management now, we can move ahead and choose the propagation and isolation topics next. Coming to this lessons, it will give you a foundation on different Transaction propagation levels like required, requires new, mandatory, supported , not supported etc. To understand, How Spring’s @Transactional works internally, I will take the help of spring AOP to log and trace different connection related calls like close(), commit(), rollback() etc. I believe this will make your transaction journey smooth. So this lessons will cover various spring AOP concepts like Aspect, Advice, Pointcuts, join points , proceeding join points as a prerequisites. By the end of this lessons, We will build a strong foundation on the different Transactional propagation levels used in Spring Boot / Spring Framework.
