亲测在使用@Transactional、@Transactional(rollbackFor = Exception.class)及catch异常之后 throw new RuntimeException();仍然不能解决线程中的事务回滚。下面使用线程所机制,进行整体的事务提交及事务回滚,代码如下:

在springboot启动类上加  @EnableTransactionManagement  注解

  线程类中添加以下代码

    @Autowired
    private PlatformTransactionManager platformTransactionManager;
    @Autowired
    private TransactionDefinition transactionDefinition;
    private Lock lock = new ReentrantLock();
    // todo 业务处理方法 数据存储异常 手动进行回滚
    public void saveMsg(String message) throws Exception {
        lock.lock();
        TransactionStatus transaction = platformTransactionManager.getTransaction(transactionDefinition);
        try {
        	//todo 具体业务,对数据库的操作 start
        	test1Service.save(test1);
        	test2Service.save(test2);
        	//end

            platformTransactionManager.commit(transaction);
        } catch (Exception e) {
            platformTransactionManager.rollback(transaction);
            e.printStackTrace();
        } finally {
            lock.unlock();
        }
    }

  注:如果无法用 @Autowired 程序启动进行对象创建,可以使用init静态注入,如果对象可以正常创建,下面代码可以忽略。

    @Autowired
    private static PlatformTransactionManager platformTransactionManager;
    @Autowired
    private static TransactionDefinition transactionDefinition;

    @Autowired
    public void init(PlatformTransactionManager platformTransactionManager,TransactionDefinition transactionDefinition
    ) {
        DriverAlfaServerHandler.platformTransactionManager = platformTransactionManager;
        DriverAlfaServerHandler.transactionDefinition = transactionDefinition;
    }

  此回滚方法亲测有效。
