Spring Data Jpa添加方法报错

Question

我在jpa接口中增加了通过字段id查询实体类的方法，代码如下：

public interface RemarkDao extends JpaRepository<Remark,Integer> {

      Remark findById(Integer id);

}

这是实体类的代码:

@Entity
@Table(name = "remark")
public class Remark {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private  Integer  id;
    @Column(name = "comment")
    private  String comment;
    @Column(name = "user_id")
    private int user_id;
    @Column(name = "post_id")
    private  int  post_id;

    public void setId(Integer id) {
        this.id = id;
    }

    public void setComment(String comment) {
        this.comment = comment;
    }

    public void setUser_id(int user_id) {
        this.user_id = user_id;
    }

    public void setPost_id(int post_id) {
        this.post_id = post_id;
    }

    public Integer getId() {
        return id;
    }

    public String getComment() {
        return comment;
    }

    public int getUser_id() {
        return user_id;
    }

    public int getPost_id() {
        return post_id;
    }
    public Remark()
    {

    }

    public Remark(int id, String comment, int user_id, int post_id) {
      
        this.comment = comment;
        this.user_id = user_id;
        this.post_id = post_id;
    }
}

实体类的字段跟注解都没问题，跟数据库一一对应 启动项目报错，我觉得是这个方法jpa没有识别出来，但是这是最基础的一个方法，貌似我手动添加方法都失效了，报错如下：
