java - Spring Transaction 不会在 @Transactional 方法中的 RuntimeException 处回滚

Question

我有这个数据库配置:

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = "com.mycompany")
public class DBConfiguration {

    @Bean(destroyMethod = "close")
    public javax.sql.DataSource dataSource() {
        DataSource ds = new DataSource();
        ds.setDriverClassName("com.mysql.jdbc.Driver");
        ds.setUrl("jdbc:mysql://localhost/v2");
        ds.setUsername("java");
        ds.setPassword("mypass");
        ds.setInitialSize(5);
        ds.setMaxActive(10);
        ds.setMaxIdle(5);
        ds.setMinIdle(2);
        ds.setRemoveAbandoned(true);
        ds.setLogAbandoned(true);
        return ds;
    }

    @Bean
    public DataSourceTransactionManager txManager()
    {
        DataSourceTransactionManager tx= new DataSourceTransactionManager(dataSource());
        return tx;
    }

}

问题已更新

我不太理解@Transaction注解是如何工作的，请考虑这个场景:

@Service
public class FirstService {
    @Transactional  //<--- this annotation seems to be mandatory for my rollback but I don't want it.
    public void test() throws Exception{
        secondService.insert();
    }
}

@Service
public class SecondService {
    @Transactional //<-- I would like to have only this method in transaction
    protected void insert() throws Exception{
        dao.insertEntity(new Entity()); //<<--- this is an SQL insert command
        throw new RuntimeException("Rollback test");
    }
}

测试代码:

@RequestMapping("/test") @ResponseBody
    public void test() throws Exception{
        firstService.test();
    }

道:

public void insertEntity(Entity e) {
        getJdbcTemplate().update(SQL_INSERT,e.getCode(),e.getName());       
    }

此测试有效，抛出的异常可以回滚事务。

为什么如果我在 firstService 上省略 @Transaction 注释就不会回滚？

似乎从@Controller 到@Service txmanager 寻找@Transaction 注释，从@Service 到(另一个)@Service 或@Component 它不寻找它。

这对我有用:

@Bean(name = "transactionManager")
    @Primary
    public PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(dataSource());
    }

请更新 spring 版本，也许还有一些日志或调试日志，看看事务是否有问题
