mybatis-plus自动生成器

1、引入maven坐标依赖

<dependencies>
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity-engine-core</artifactId>
        <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus</artifactId>
        <version>3.4.1</version>
    </dependency>
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-generator</artifactId>
        <version>3.4.1</version>
    </dependency>
    <!-- mysql-connector-java -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.20</version>
    </dependency>
</dependencies>

2、实例代码

public class Test {
    public static void main(String[] args) {
        generator();
    }

    public static void generator() {
        //1、全局配置
        GlobalConfig globalConfig = new GlobalConfig();
        //不支持AR模式
        globalConfig.setActiveRecord(false)
                //生成路径
                .setOutputDir("D:\\IntelliJ_WorkSpace\\workspace07\\mybatisplus\\src\\main\\java")
                //文件覆盖
                    .setFileOverride(true)
                //主键自增策略
                    .setIdType(IdType.AUTO)
                //设置生成接口名的首字母是否为I
//              .setServiceName("")     
                .setAuthor("quzp")
                //设置基本的映射文件返回的
                .setBaseResultMap(true)
                //设置生成SQL片段
                .setBaseColumnList(true);  
        //2、数据源配置
        DataSourceConfig dataSourceConfig = new DataSourceConfig();
        dataSourceConfig.setDbType(DbType.MYSQL)
                .setDriverName("com.mysql.jdbc.Driver")
                .setUrl("jdbc:mysql://localhost:3306/mybatis")
                .setUsername("root")
                .setPassword("root");
        //3、策略配置
        StrategyConfig strategyConfig = new StrategyConfig();
        strategyConfig.setCapitalMode(true)  //全局大小写
                .setNaming(NamingStrategy.underline_to_camel)  //驼峰命名
                .setInclude("employee","department");//生成的表
        //4、包名策略配置
        PackageConfig packageConfig = new PackageConfig();
        packageConfig.setParent("com.test")
                .setEntity("entity")
                .setMapper("mapper")
                .setXml("mapper")
                .setService("service")
                .setServiceImpl("service.impl")
                .setController("controller");
        //5、整合配置
        AutoGenerator autoGenerator = new AutoGenerator();
        autoGenerator.setGlobalConfig(globalConfig)
                .setDataSource(dataSourceConfig)
                .setStrategy(strategyConfig)
                .setPackageInfo(packageConfig);
        //6、执行
        autoGenerator.execute();
    }
}

执行即可。
