二、问题描述
业务想接入改造成TCC，所以先用一个简单的例子验证一下特性，发现一直达不到效果。
1.tcc相关注解在接口
代码如下：
```
public class GlobalTransactionTestController {
@GetMapping("/testTcc")
@GlobalTransactional
public ResultGeneralModel<Boolean> testTcc() {
log.info("测试tcc事务务");
tccTestService.prepare(null,123);
int i = 1/0;
return ResultGeneralModel.newSuccess(Boolean.TRUE);
}
}
```
```
@LocalTCC
public interface TccTestService {
@TwoPhaseBusinessAction(name = "TccTestBean", commitMethod = "commit",
rollbackMethod = "rollback")
void prepare(BusinessActionContext
actionContext,@BusinessActionContextParameter(paramName = "a") int a);;
void commit(BusinessActionContext actionContext);
void rollback(BusinessActionContext actionContext);
}
```
```
@Component
@Slf4j
public class TccTestServiceImpl implements TccTestService {
@Override
public void prepare(BusinessActionContext actionContext, int a) {
//一些访问db的动作，省略了，非常简单
log.info("prepare 被调用");
}
@Override
public void commit(BusinessActionContext actionContext) {
log.info("commit 被调用");
}
@Override
public void rollback(BusinessActionContext actionContext) {
log.info("rollback 被调用");
}
}
```
启动正常，tcc resource注册成功:
```
INFO org.apache.seata.core.rpc.netty.RmNettyRemotingClient [main] [] [] will
register resourceId:TccTestBean
```
代码执行后报错，报错日志：
```

debug定位了一下报错的地方，这里拿到的接口是SpringProxy，八成是spring代理的，这个接口里肯定是没有的preapre
org.apache.seata.rm.tcc.interceptor.TccActionInterceptorHandler#parseAnnotation

2.tcc相关注解在实现类
看了和tcc使用的相关issue，怀疑是注解的位置导致的，因此我将注解移动到了实现类中，
```
public interface TccTestService {
void prepare(BusinessActionContext actionContext, int a);;
void commit(BusinessActionContext actionContext);
void rollback(BusinessActionContext actionContext);
}
```
```
@Component
@Slf4j
@LocalTCC
public class TccTestServiceImpl implements TccTestService {
@Override
@TwoPhaseBusinessAction(name = "TccTestBean", commitMethod = "commit",
rollbackMethod = "rollback")
public void prepare(BusinessActionContext actionContext,
@BusinessActionContextParameter(paramName = "a") int a) {
//一些访问db的动作，省略了，非常简单
log.info("prepare 被调用");
}
@Override
public void commit(BusinessActionContext actionContext) {
log.info("commit 被调用");
}
@Override
public void rollback(BusinessActionContext actionContext) {
log.info("rollback 被调用");
}
}
```
启动后，虽然tm 和rm注册成功. 但是并没有看到tcc resource注册成功的这条日志:
```
INFO org.apache.seata.core.rpc.netty.RmNettyRemotingClient [main] [] [] will
register resourceId:TccTestBean
```
代码执行后，确实返回了/ by zero异常，但是cacnel方法并没有被回调。
以上，希望能得到帮助，多谢！
