创建实体类

package com.kinda.kindanotify.pojo.entity;

import jakarta.persistence.*;
import lombok.Builder;

@Entity
@Builder
@Table(name = "event")
public class Event {
    private Integer id;
    private String title;
    private String message;

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    public Integer getId() {
        return id;
    }

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

    @Column(name = "title")
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    @Column(name = "message")
    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public Event() {
    }

    public Event(Integer id, String title, String message) {
        this.id = id;
        this.title = title;
        this.message = message;
    }

    @Override
    public String toString() {
        return "Event{" +
                "id=" + id +
                ", title='" + title + '\'' +
                ", message='" + message + '\'' +
                '}';
    }
}

创建dao/repository层

package com.kinda.kindanotify.repository;

import com.kinda.kindanotify.pojo.entity.Event;
import org.springframework.data.jpa.repository.JpaRepository;

public interface EventRepo extends JpaRepository<Event, Integer> {

}

测试

package com.kinda.kindanotify;

import com.kinda.kindanotify.pojo.entity.Event;
import com.kinda.kindanotify.repository.EventRepo;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class KindaNotifyApplicationTests {

    @Autowired
    private EventRepo eventRepo;

    // @Test
    // void contextLoads() {
    //     System.out.println("初始化数据库表");
    // }

    // 测试JPA提供的方法
    /**
     * 测试添加事件
     */
    @Test
    void testAddEvent(){
        Event event = new Event();
        event = event.builder().title("测试标题").message("测试信息").build();
        System.out.println(event);
        eventRepo.save(event);
    }

}
