GlobalConfig config = new GlobalConfig();
//1.全局配置
config.setAuthor("wwz");
config.setOutputDir("F:\\Workspaces\\IDEA\\mybatisplus\\src\\main\\java");
config.setFileOverride(true);
config.setServiceName("%sService"); //默认生成IEmployeeService格式的service   %s去掉I
config.setBaseResultMap(true) ;   //是否生成基本结果集映射
config.setBaseColumnList(true);  //是否生成数据库列 做通用查询列
//2.数据源等配置
DataSourceConfig dsConfig = new DataSourceConfig();
dsConfig.setDbType(DbType.MYSQL);

//3.策略配置

//4.包名策略

packageConfig .setMapper("mapper");
packageConfig.setEntity("model");

packageConfig.setController("controller");

//5.整合配置
AutoGenerator autoGenerator = new AutoGenerator();
autoGenerator.setGlobalConfig(config);
autoGenerator.setDataSource(dsConfig);
autoGenerator.setPackageInfo(packageConfig);

//6.执行
autoGenerator.execute();

}

放到main方法上执行就行了
