This article mainly introduces the relevant knowledge of "spring in service layer method error reporting transaction will not be rolled back how to solve", the editor shows you the operation process through the actual case, the operation method is simple, fast and practical. I hope this article "spring method in service layer error reporting transaction will not be rolled back how to solve" article can help you solve the problem.

Spring will not roll back @ Transactional (rollbackFor = {Exception.class}) public void insertData () throws Exception {/ / business code 1 business1 (); / / business code 2 business2 (); / / business code 3 business3 () } public void business1 () {/ / omit business operations here} public void business2 () {/ / omit business operations here} public void business3 () {/ / omit business operations here}

When the above code executes the insertData method in the service layer, there is an error in the code execution in business3, and the operations in business1 and business2 are not rolled back

Solution method

Method 1: catch the exception in the service method and throw the runtime exception out at the same time

@ Transactional (rollbackFor = {Exception.class}) public void insertData () throws Exception {try {/ / Business Code 1 business1 (); / / Business Code 2 business2 (); / / Business Code 3 business3 ();} catch (Exception) {throw new RuntimeException (e);}}

Method 2: catch an exception in the service method and manually roll back the transaction

Service manual rollback issu

If the management of service layer things is configured for spring.

In some businesses, rollback is required. Normally, a runtime exception is thrown.

Throw new RuntimeException ()

Only in this way, the code ends. If you want to return an error message to the user, which is not convenient, you can add the following code to manually roll back in catch.

TransactionAspectSupport.currentTransactionStatus () .setRollbackOnly ()

This not only returns the error message normally, but also maintains the atomicity of things.
