SpringBoot集成mybatis-plus

一、导入依赖

<!-- 数据库驱动 -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.30</version>
    </dependency>

    <!-- 阿里巴巴数据源druid -->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid-spring-boot-starter</artifactId>
        <version>1.2.13</version>
    </dependency>

    <!-- 代码自动生成器 -->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-generator</artifactId>
        <version>3.5.3</version>
    </dependency>

    <!-- mybatis plus依赖包 -->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.5.2</version>
    </dependency>

    <!-- velocity模板引擎 -->
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity-engine-core</artifactId>
        <version>2.3</version>
    </dependency>

二、配置数据源

spring:
  datasource:
    name: test
    url: jdbc:mysql://localhost:3306/aaaa?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver

三、新增mybatis配置类

package com.tireba.common.config;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Configuration;

/**
 * @Author Tireba
 * @Date 2022/10/23 10:12
 * @Desc 数据库配置
 */
@Configuration
@MapperScan("com.tireba.common.*")
public class MybatisConfig {
}

四、新增代码生成类

package com.tireba.common.utils;

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import java.sql.SQLException;

/**
 * @Author Tireba
 * @Date 2022/10/23 8:36
 * @Desc 代码生成器
 */
public class Generator {

    /**
     * 数据源配置
     */
    private static final String URL = "jdbc:mysql://localhost:3306/aaaa?useUnicode=true&useSSL=false&characterEncoding=utf8";

    /**
     * 执行main方法生成代码
     * @param args
     */
    public static void main(String[] args) throws SQLException {
        FastAutoGenerator.create(URL, "root", "root")
            // 全局配置
            .globalConfig((scanner, builder) -> builder.author(scanner.apply("请输入作者名称")))
            // 包配置
            .packageConfig((scanner, builder) -> builder.parent(scanner.apply("请输入包名")))
            // 策略配置
            .strategyConfig((scanner, builder) -> builder.addInclude(scanner.apply("请输入表名，多个表名用,隔开")))
            /*
                模板引擎配置，默认 Velocity 可选模板引擎 Beetl 或 Freemarker 或 Enjoy
                如果pom文件中没添加引擎模板依赖，执行时会产生异常
               .templateEngine(new BeetlTemplateEngine())
               .templateEngine(new FreemarkerTemplateEngine())
               .templateEngine(new EnjoyTemplateEngine())
             */
            .execute();
    }

}
