解决调用Spring注解式事务方法不生效的问题

看如下代码

@Component
public class FooServiceImpl implements FooService {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Override
    @Transactional(rollbackFor = RollbackException.class)
    public void insertThenRollback() throws RollbackException {
        jdbcTemplate.execute("INSERT INTO FOO (BAR) VALUES ('BBB')");
        throw new RollbackException();
    }

    @Override
    public void invokeInsertThenRollback() throws RollbackException {
        insertThenRollback();
    }
}

方法 invokeInsertThenRollback() 调用一个有 @Transactional 注释的方法，这时，事务未生效。

有两种方法可以解决。

方法一，把自身 FooService 注入进来。

@Component
public class FooServiceImpl implements FooService {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Autowired
    private FooService fooService;

    @Override
    @Transactional(rollbackFor = RollbackException.class)
    public void insertThenRollback() throws RollbackException {
        jdbcTemplate.execute("INSERT INTO FOO (BAR) VALUES ('BBB')");
        throw new RollbackException();
    }

    @Override
    public void invokeInsertThenRollback() throws RollbackException {
//        insertThenRollback();
        fooService.insertThenRollback();       
    }
}

方法二，调用 AopContext.currentProxy() 获取代理类

@Component
public class FooServiceImpl implements FooService {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Override
    @Transactional(rollbackFor = RollbackException.class)
    public void insertThenRollback() throws RollbackException {
        jdbcTemplate.execute("INSERT INTO FOO (BAR) VALUES ('BBB')");
        throw new RollbackException();
    }

    @Override
    public void invokeInsertThenRollback() throws RollbackException {
//        insertThenRollback();
        ((FooService) (AopContext.currentProxy())).invokeInsertThenRollback();
    }
}
