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);
}
}
5. IDEA操作
在idea里可以创建SQLite 的数据库和表
