SpringBoot 整合 SQLite 数据库

article 2024/12/24 2:21:57

1、SQLite 简介

SQLite 是一个很轻量的关系型数据库，不需要安装服务，数据存储在文件里。

2、引入pom依赖

        <!-- SQLite  -->
        <dependency>
            <groupId>org.xerial</groupId>
            <artifactId>sqlite-jdbc</artifactId>
            <version>3.34.0</version>
        </dependency>


        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.2.9</version>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.1</version>
        </dependency>

3. 修改配置文件

spring:
  datasource:
    url: jdbc:sqlite:identifier.db
    driver-class-name: org.sqlite.JDBC

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    cache-enabled: true
    map-underscore-to-camel-case: false
  global-config:
    db-config:
      logic-delete-field: isDeleted
      logic-not-delete-value: 0
      logic-delete-value: 1

identifier.db 就是生成的SQLite 数据库文件

4. 代码

Mapper

package com.hejjon.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.hejjon.entity.User;

public interface UserMapper extends BaseMapper<User> {
    
}

Controller

@RestController
@RequestMapping("/user")
public class UserController {

    @Resource
    private UserMapper userMapper;

    @GetMapping("getById")
    public User getById(@RequestParam("id") String id) {

        return userMapper.selectById(id);
    }

}
