How @Transactional works ? Transactional propagation explained ! Transaction Management

[@rahulbhandari8861]

Probably the best explanation of Transaction management on KZbin

[@od10engineer]

I have watched many videos in my 4-5 years of Software Engineer journey. This is the only video which taught me transaction concept clearly and in a simpler way. Thank you so much for the efforts. I will rock in the interview when interviewer will ask any questions on transaction topic.

The best Explanation!! thanks

[@sunnymetkar7174]

Simply brilliant. Loved the way you used aop and handler to log details of connection methods to explain transaction boundaries unlike other tutorials which just show the end result in database. Keep it up .

[@TheAnkjain77]

Simply.....mindblowing

Super clear explaination Never realised 2 hour endend

[@praveenmourya9948]

Simple and best example. And one question if we want to define the scope of transactional between the method call, how can we achieve that purpose?

Hi Abhash, Why so we need to create Datasource ourself when it can be auto configured by spring via yaml.

[@tararamgoyal2220]

Hi can you tell, why @transactional not work with @modifying ?

[@hackstreet781]

Awesome

[@roronoa_d_law1075]

1:23:50 why don't you use spring aop with target ConnectionImpl instead of using invocationHandler ? Edit 1:37:25 thanks akhil for asking 😂

[@keshavrjaput1522]

is @Transactional mandetory in method b()??? when method A() has a @Transactional??

[@venkatnani6940]

Can u show example on Global transactions because no where in Google and in youtube working code is not there

If a block of code execute at the time server stop then b() method not called Then a class is rollback the transaction or not ?

[@harshhwardhanrai3716]

Thanks

[@rishanaznin8636]

Such an awesome explanatory video. thanks. But I have run into a weird problem I have @Transaction(readOnly=true) in my implementation class. and In that class I have a method which I annotated with @Transaction. Problem is its not overriding my class level annotation! its still acting like readonly transaction. can you tell me why is this happening? and interestingly if I annotate my interface method with @Transactional then it works perfectly.

[@khajalieubarrie5088]

Hello rishan..Very good problem that led me to understanding @Transaction propagation and Isolation levels better. By default using @Transactional on an interface, class or method, “readOnly=true”. So it’s like @Transactional = @Transactional(readOnly=true). So your method @Transactional actually overrides the class level annotation. Try to set another Isolation level at the method to see the effect.

[@khajalieubarrie5088]

In addition REQUIRED PROPAGATION is also the default. @Transactional annotation on an interface is not recommended as the annotation “can be silently ignored” by AspectJ because Java doesn’t inherit Annotations from interfaces. Attempting a rollback scenario by throwing a RuntimeExceltion for example will giving u an indication if your @Transactional at interface level works alright.

[@mareshkrishnanv4995]

If 2 api calls first call invoke the method one @transactional and first api call internally called second api call and second api call also @transactonal annotations..incase any issue happening in second api db side will entire transaction will be committed or rollback or what will happen..in this video your explain only one way transactions

[@kunwar_sagar]

With hibernate or jpa, when is the connection opened and closed when we call getData method in Service? I see we don't use @Transactional for get methods.

[@SeleniumExpress]

In that case, when you are making a API call , the get call will open the connection. I have given a similar example with Spring JDBC update method.

[@kunwar_sagar]

@@SeleniumExpress got it, thank you for the reply
