谢谢。当我把注解全部从接口转移到实现类后，问题解决了。
这是接口类
```java
public interface AccountTCCService {
boolean deduct(
BusinessActionContext ctx,
String userId,
int money
);
boolean deductConfirm(BusinessActionContext ctx);
boolean deductCancel(BusinessActionContext ctx);
}
```
这是实现类
```java
@Service
@Slf4j
@LocalTCC
public class AccountTCCServiceImpl implements AccountTCCService {
@Autowired
private AccountMapper accountMapper;
@Autowired
private AccountFreezeMapper accountFreezeMapper;
@Override
@Transactional
@TwoPhaseBusinessAction(name = "deduct", commitMethod = "deductConfirm",
rollbackMethod = "deductCancel")
public boolean deduct(
BusinessActionContext ctx,
@BusinessActionContextParameter(paramName = "userId") String
userId,
@BusinessActionContextParameter(paramName = "money") int money
) {
System.out.println(ctx);//第一处断点
if (ctx != null){
Object userId2 = ctx.getActionContext("userId");
Object money2 = ctx.getActionContext("money");
System.out.println(userId2);
System.out.println(money2);
}
throw new RuntimeException("扣款失败，可能是余额不足！");
}
@Override
public boolean deductConfirm(BusinessActionContext ctx) {
return true;
}
@Override
public boolean deductCancel(BusinessActionContext ctx) {
Object userId = ctx.getActionContext("userId");//第二处断点
Object money = ctx.getActionContext("money");
System.out.println(userId);
System.out.println(money);
return false;
}
}
```
