Java 实体创建抛出错误“；无法解析符号'；保存'&引用；

我有回购协议、实体、域和控制器。Intelliji将不会编译，错误与LicenseSignmentEntity CreateIdentity=new ICenseSignmentRepository.save（createEntity）有关；我不确定我做错了什么。多谢各位

}

您可以通过以下方式将数据保存到存储库中。假设您必须使用任何弹簧靴来保存post 这将是售后服务接口-

public interface PostService {
    public void save(Post thePost);
}

这是我的PostRepository接口

public interface PostRepository extends JpaRepository<Post, Integer> {

}

这些问题是中国的“新”问题

不需要，抱歉

请在问题中输入您得到的确切错误。

@Service
public class PostServiceImpl implements PostService {

    private PostRepository postRepository;

    @Autowired
    public PostServiceImpl(PostRepository thePostRepository) {
        this.postRepository = thePostRepository;

     @Override
    public void save(Post thePost) {
        postRepository.save(thePost);
    }

    }

LicenseAssignmentEntity createdEntity = new licenseAssignmentRepository.save(createEntity);
