SpringBoot中进行事务回滚的方法

@Component
public class MyService {
    @Autowired
    private TransactionTemplate transactionTemplate;
    public void doSomething() {
        transactionTemplate.execute(new TransactionCallbackWithoutResult() {
            @Override
            protected void doInTransactionWithoutResult(TransactionStatus transactionStatus) {
                // 执行业务逻辑
                // 如果需要回滚事务，调用TransactionStatus对象的setRollbackOnly方法
                if (someErrorCondition) {
                    transactionStatus.setRollbackOnly();
                }
            }
        });
    }
}

@Service
@Transactional(rollbackFor = Exception.class)
public class MyService {
    public void doSomething() {
        // 执行业务逻辑
        // 如果需要回滚事务，抛出一个RuntimeException
        if (someErrorCondition) {
            throw new RuntimeException("需要回滚事务");
        }
    }
}

import org.springframework.stereotype.Service;
import org.springframework.transaction.interceptor.TransactionAspectSupport;
@Service
public class MyService {
    public void doSomething() {
        // 执行业务逻辑
        // 如果需要回滚事务，调用TransactionAspectSupport.currentTransactionStatus().setRollbackOnly()方法
        if (someErrorCondition) {
            TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
        }
    }
}
