2025 IDEA创建一个Maven 空项目（SpringBoot+Mybatis-Flex+MySql+MVC结构的项目生成器工具类以及使用）【附示例图文讲解】

一、打开idea创建项目

二、加单选择几个pom依赖【后续会手动修改pom依赖】

三、运行MAVEN

四、修改pom.xml文件

1、手动新增几个必须的依赖：数据库、mvc生成器

    <dependencies>
        <!--   mysql     -->
        <dependency>
            <groupId>com.mysql</groupId>
            <artifactId>mysql-connector-j</artifactId>
            <version>8.0.32</version>
        </dependency>


        <!--      mybatis-flex  SpringBoot版本    -->
        <dependency>
            <groupId>com.mybatis-flex</groupId>
            <artifactId>mybatis-flex-spring-boot-starter</artifactId>
            <version>1.8.6</version>
        </dependency>

        <!--    MyBatis-Flex 代码生成器    -->
        <dependency>
            <groupId>com.mybatis-flex</groupId>
            <artifactId>mybatis-flex-codegen</artifactId>
            <version>1.8.6</version>
        </dependency>
        <dependency>
            <groupId>com.mybatis-flex</groupId>
            <artifactId>mybatis-flex-processor</artifactId>
            <version>1.8.6</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
            <version>4.0.3</version>
        </dependency>

    </dependencies>

2、修改最后一处项目构建配置，将 true改为 false

 

3、完整的pom.xml【仅供参考】

</project>

五、Mybatis-Flex生成器的工具类：CodegenUtil

1、我重新创建了一个util包，如图所示（仅供参考）：

2、生成器直接在main方法中运行，然后右侧会有MVC结构项目框架

3、工具类源码 

package com.example.demo.utils;

import com.mybatisflex.codegen.Generator;
import com.mybatisflex.codegen.config.GlobalConfig;
import com.zaxxer.hikari.HikariDataSource;

public class CodegenUtil {

    public static void main(String[] args) {
        //配置数据源
        HikariDataSource dataSource = new HikariDataSource();
        dataSource.setJdbcUrl("jdbc:mysql://127.0.0.1:3306/数据库名称?characterEncoding=utf-8");
        dataSource.setUsername("数据库账号");
        dataSource.setPassword("数据库密码");
        //创建配置内容，两种风格都可以
        GlobalConfig globalConfig = createGlobalConfigUseStyle1();

        //通过 datasource 和 globalConfig 创建代码生成器
        Generator generator = new Generator(dataSource, globalConfig);

        //生成代码
        generator.generate();
    }

    /**
     * 代码生成器方式1
     *
     * @return
     */
    public static GlobalConfig createGlobalConfigUseStyle1() {
        //创建配置内容
        GlobalConfig globalConfig = new GlobalConfig();

        //设置根包
        globalConfig.setBasePackage("com.example.demo");

        //文档注释 作者名
        globalConfig.getJavadocConfig().setAuthor("作者姓名").setSince("创建日期");

        //设置表前缀和只生成哪些表，赌赢的entity类
        //示例:globalConfig.setGenerateTable("user","type","order");
        globalConfig.setGenerateTable("数据表名1","数据表名2","数据表名3");


        //设置生成 entity
        globalConfig.enableEntity();
        // 启用 Lombok
        globalConfig.setEntityWithLombok(true);

        // 设置项目的JDK版本，项目的JDK为14及以上时建议设置该项，小于14则可以不设置
        // globalConfig.setJdkVersion(17);

        //启用 Controller 生成
        globalConfig.enableController();

        //启用 Service 生成
        globalConfig.enableService();

        //启用 ServiceImpl 生成
        globalConfig.enableServiceImpl();


        //设置生成 mapper
        globalConfig.setMapperGenerateEnable(true);

        //启用 MapperXml 生成
        globalConfig.enableMapperXml();

        //	启用 TableDef 生成
        globalConfig.enableTableDef();
        //不设置会重复类
        globalConfig.getTableDefConfig()
                .setClassPrefix("My")
                .setClassSuffix("Def");

        //可以单独配置某个列
        //ColumnConfig columnConfig = new ColumnConfig();
        //columnConfig.setColumnName("tenant_id");
        //columnConfig.setLarge(true);
        //columnConfig.setVersion(true);
        //globalConfig.setColumnConfig("tb_account", columnConfig);

        return globalConfig;
    }


}

六、配置appliaction.properties文件

# 项目端口号
server.port=10001

# application.properties 示例
spring.datasource.url=jdbc:mysql://localhost:3306/数据库名称?useSSL=false&serverTimezone=UTC
spring.datasource.username=数据库账号
spring.datasource.password=数据库密码
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

七、删除示例的代码

八、启动类上添加注解

        在启动类添加上自动扫描指定包路径下的 Mapper 接口，并注册为 Spring Bean，从而避免手动为每个 Mapper 接口添加 @Mapper 注解

//根据你自己包路径填写
@MapperScan("com.自己的mapper包路径.mapper")

 九、正式启动【Mybatis-Flex启动速度很快，我很喜欢的】

1、如果有报错，点击：启用注解处理，再运行就可以
