在以下代码中,抛出Exception
并不会回滚该事务,但会抛出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. :(
}
}
我的存储库:
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
为什么会发生这种情况?

来自docs:
任何RuntimeException都会触发回滚,而任何已检查的Exception都不会。
您可以通过在rollbackFor
注释上指定rollbackForClassName
或@Transactional
来覆盖此行为。有关完整的选项,请参阅上述文档。
