Throwing a RuntimeException causes a transaction to be rolled back, but Exception is not used in the spring boot application

Question

In the following code, throwing an Exception does not cancel the transaction, but throws a RuntimeException .

 @Service public class HelloService { @Autowired protected CustomerRepository repository; @Transactional public void run() throws Exception { repository.save(new Customer("Jack", "Bauer")); throw new RuntimeException("Kabooom!!!"); //Transaction is rolled back. Database is empty :) //throw new Exception("Kabooom!!!"); //If this is used instead the records are inserted into the database. :( } } 

My repository:

 public interface CustomerRepository extends CrudRepository<Customer, Long> { } 

Spring boot appliction.properties:

 # DataSource settings: set here configurations for the database connection spring.datasource.url = jdbc:mysql://localhost/hobbadb spring.datasource.username = root spring.datasource.password = spring.datasource.driverClassName = com.mysql.jdbc.Driver # Specify the DBMS spring.jpa.database = MYSQL # Show or not log for each sql query spring.jpa.show-sql = true # Hibernate settings are prefixed with spring.jpa.hibernate.* spring.jpa.hibernate.ddl-auto = update spring.jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect spring.jpa.hibernate.naming_strategy = org.hibernate.cfg.ImprovedNamingStrategy spring.jpa.hibernate.hbm2ddl.auto= create-drop 

Any ideas why this is happening?

From docs :

Any RuntimeException throws a rollback, and any thrown Exception does not.

You can override this behavior by specifying rollbackFor or rollbackForClassName in the @Transactional annotation. See the above documents for a complete set of options.
