使用（以下教程仅适用 3.5.1 以上版本，对历史版本的不兼容）

快速生成

FastAutoGenerator.create("url", "username", "password")
	.globalConfig(builder -> {
		builder.author("baomidou") // 设置作者
            .enableSwagger() // 开启 swagger 模式
			.fileOverride() // 覆盖已生成文件
			.outputDir("D://"); // 指定输出目录
	})
	.packageConfig(builder -> {
		builder.parent("com.baomidou.mybatisplus.samples.generator") // 设置父包名
			.moduleName("system") // 设置父包模块名
            .pathInfo(Collections.singletonMap(OutputFile.xml, "D://")); // 设置mapperXml生成路径
	})
	.strategyConfig(builder -> {
		builder.addInclude("t_simple") // 设置需要生成的表名
			.addTablePrefix("t_", "c_"); // 设置过滤表前缀
	})
	.templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
	.execute();

交互式生成

FastAutoGenerator.create(DATA_SOURCE_CONFIG)
    // 全局配置
    .globalConfig((scanner, builder) -> builder.author(scanner.apply("请输入作者名称？")).fileOverride())
    // 包配置
    .packageConfig((scanner, builder) -> builder.parent(scanner.apply("请输入包名？")))
    // 策略配置
    .strategyConfig(builder -> builder.addInclude("t_simple"))
    /*
        模板引擎配置，默认 Velocity 可选模板引擎 Beetl 或 Freemarker
       .templateEngine(new BeetlTemplateEngine())
       .templateEngine(new FreemarkerTemplateEngine())
     */
    .execute();
