Spring手动提交事务_spring手动提交事物

Spring事务的手动提交

• 事务背景：

Spring事务开启，常见的可以用基于注解的方式进行： @Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRES_NEW)

• 手动进行Sring事务的提交

import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.TransactionDefinition;
@Service
@Slf4j
publi class serviceA(){
    @Resource
    DataSourceTransactionManager dataSourceTransactionManager;

    @Resource
    TransactionDefinition transactionDefinition;

	//基于Spring手动的事务提交处理
	public void methodA(){
        //开启事务
        TransactionStatus transaction = dataSourceTransactionManager.getTransaction(transactionDefinition);
        boolean isSuccess=true;
        try {
           //...
            
        }catch (Exception e){
            log.error("Error",e);
            isSuccess=false;
        }finally {
            if(!isSuccess){
                //手动回滚事务
                dataSourceTransactionManager.rollback(transaction);
            }else {
                //手动提交事务
                dataSourceTransactionManager.commit(transaction);
            }
        }
	}
}
