抛出RuntimeException导致事务回滚,但Exception不在spring启动应用程序中

Question

在下面的代码中抛出一个Exception不回滚事务,但抛出一个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

任何想法为什么会这样？

来自文档:

任何RuntimeException都会触发回滚,而任何已检查的Exception都不会.

您可以通过指定rollbackFor或rollbackForClassName在@Transactional注释上覆盖此行为.有关完整选项,请参阅上述文档.
