版本：3.1.0
代码如下：
public interface UserService extends IService {
boolean modify(User entity);
}
public class UserServiceImpl extends ServiceImpl implements UserService {
@Override
public boolean modify(User entity) {
return new LambdaUpdateChainWrapper<>(this.baseMapper)
.eq(User::getStatus, entity.getStatus())
.eq(User::getType, entity.getType())
.update(entity);
}
}
直接使用UserMapper可以调用成功，但是使用UserService.modify就报错

@Autowired
protected UserService UserService;
@Autowired
protected UserServiceImpl UserService;
注入接口报错，注入实现类不报错，难道是找不到实现类，求大神解答？？？

已解决。
有点坑爹啊，居然是@MapperScan配置有问题，需要精确到包名，比如：
@MapperScan("com.user.mapper")
