spring-boot 整合mybatis反向代码生成

一、引入maven依赖包

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.3.1</version>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.2</version>
        </dependency>

二、创建反向生成类

public class MyTest {

    @Test
    public void testGenerator() {
        AutoGenerator autoGenerator = new AutoGenerator();

    ​    //全局配置
    ​    GlobalConfig globalConfig = new GlobalConfig();
    ​    globalConfig.setAuthor("ttb")
    ​            .setOutputDir("E:\\self_project\\ttb\\src\\main\\java")//设置输出路径
    ​            .setFileOverride(true)//设置文件覆盖
    ​            .setIdType(IdType.AUTO)//设置主键生成策略
    ​            .setServiceName("%sService")//service接口的名称
    ​            .setBaseResultMap(true)//基本结果集合
    ​            .setBaseColumnList(true)//设置基本的列
    ​            .setControllerName("%sController");

    ​    //配置数据源
    ​    DataSourceConfig dataSourceConfig = new DataSourceConfig();
    ​    dataSourceConfig.setDriverName("com.mysql.jdbc.Driver").setUrl("jdbc:mysql://localhost:3306/base?serverTimezone=UTC")
    ​            .setUsername("root").setPassword("123456");

    ​    //策略配置
    ​    StrategyConfig strategyConfig = new StrategyConfig();
    ​    strategyConfig.setCapitalMode(true)//设置全局大写命名
    ​            .setNaming(NamingStrategy.underline_to_camel)//数据库表映射到实体的命名策略
    ​            .setInclude();

    ​    //包名配置
    ​    PackageConfig packageConfig = new PackageConfig();
    ​    packageConfig.setParent("com.ttb").setMapper("mapper")
    ​            .setService("service").setController("controller")
    ​            .setEntity("bean").setXml("mapper");

    ​    autoGenerator.setGlobalConfig(globalConfig).setDataSource(dataSourceConfig)
    ​            .setStrategy(strategyConfig).setPackageInfo(packageConfig);

    ​    autoGenerator.execute();
    }

}

三、运行结果

出现上述结果就说明运行成功，可以去项目里查看了。
