java code

package com.test;

 @Component

public class TService {

@Autowired JdbcTemplate jdbcTemplate;

@Transactional(rollbackFor = Exception.class)
public void tt() throws Exception{

        jdbcTemplate.update("insert into t_test values(1)");
        jdbcTemplate.update("insert into t_test(dd) values(1)");

    }

}

controller code

    @Controller("")
public class Tcontroller {

    @Autowired TService ts;

Answer 1

I've got the same problem when I was throwing null at tests. It appears to be @Transaction works with an instance or subclass of RuntimeException only.

Which Exception is not.

Answer 2

A transaction is always rolled back if it encounters a unchecked runtime exception. Your problem is probably caused by the fact that you caught the exception and then re-throw it. It's quite unnecessary to do such a thing.

Section 16.5.3 : In its default configuration, the Spring Framework's transaction infrastructure code only marks a transaction for rollback in the case of runtime, unchecked exceptions; that is, when the thrown exception is an instance or subclass of RuntimeException. ( Errors will also - by default - result in a rollback). Checked exceptions that are thrown from a transactional method do not result in rollback in the default configuration.
