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：

2024-12-04 20:56:12.615 ERROR[http-nio-8080-exec-1] [] [] java.lang.NoSuchMethodException: org.springframework.aop.SpringProxy.prepare(org.apache.seata.rm.tcc.api.BusinessActionContext, int)

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。

甚至isLocalTCC都没有命中：

   private boolean isLocalTCC(Class<?> classType) {
        Set<Class<?>> interfaceClasses = ReflectionUtil.getInterfaces(classType);
        for (Class<?> interClass : interfaceClasses) {
            if (interClass.isAnnotationPresent(LocalTCC.class)) {
                return true;
            }
        }
        return classType.isAnnotationPresent(LocalTCC.class);
    }

以上，希望能得到帮助，多谢！

thanks for your feedback.

请问这个问题计划会在哪个版本的到修复

[wxrqforever]

@funky-eyes 老哥 这个有计划修复的时间吗？是否有其他使用方式可以规避，或者有修复的大体方案，我这边也可以尝试修复，我这的业务需要使用localtcc的模式的需求，多谢帮忙看看。
