seata分布式事务不生效

Fegin调用使用了Fallback降级或抛出的异常被全局处理

解决：

1.通过 GlobalTransactionContext.reload(RootContext.getXID()).rollback() 进行手动回滚

==============服务A
@Service
public class ServiceAImpl implements IServiceA
{
 
    private static final Logger log = LoggerFactory.getLogger(ServiceAImpl.class);
 
    @Autowired
    private IServiceB serviceB;
    @Autowired
    private IServiceC serviceC;
    
    @Override
    @GlobalTransactional
    @Transactional
    public Boolean doA() {
        Integer bStatus = serviceB.doB();
        if(bStatus == 0){//在Mybatis中，返回值为0证明插入失败
            //手动回滚
            GlobalTransactionContext.reload(RootContext.getXID()).rollback();
            return false;
        }
        Integer cStatus = serviceC.doC();
        if(cStatus == 0){//在Mybatis中，返回值为0证明插入失败
            //手动回滚
            GlobalTransactionContext.reload(RootContext.getXID()).rollback();
            return false;
        }
        //......
    }
 
}
 
===============服务B
@Service
public class ServiceBImpl implements IServiceB
{
 
    private static final Logger log = LoggerFactory.getLogger(ServiceBImpl.class);
 
    @Override
    @Transactional(propagation = Propagation.REQUIRES_NEW)
    public Boolean doB() {
        //......
        Integer insertStatus = serviceBDAO.insert();
        return insertStatus;
    }
 
}
 
===============服务C
@Service
public class ServiceCImpl implements IServiceC
{
 
    private static final Logger log = LoggerFactory.getLogger(ServiceCImpl.class);
 
    @Override
    @Transactional(propagation = Propagation.REQUIRES_NEW)
    public Boolean doC() {
        //......
        Integer insertStatus = serviceCDAO.insert();
        return insertStatus;
    }
 
}

　　2.直接在FallbackFactory实现类直接将异常抛出或者不实现fallbackFactory
