无法运行示例spring boot应用程序

Question

我跟踪了下面的文章并设置了项目

https://www.callicoder.com/spring-boot-rest-api-tutorial-with-mysql-jpa-hibernate/

我附上POM以供参考。当我运行该项目时，我得到：

NoteRepository接口：

package com.example.easynotes.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import com.example.easynotes.model.Note;
import org.springframework.stereotype.Repository;

@Repository
public interface NoteRepository extends JpaRepository<Note,Long> {

}

Answer 1

1. 用@repository注释标记noterepository类。
2. 并用@enablejparepositories(basePackages={“com.example.easyNotes.repository”}）
标记主类
