SpringBoot3.x + mp代码生成器（更新系列）

小伙伴们，有没有这样一个体验，每次开始写一个项目时，搭建项目环境，建entity，mapper，service，controller层文件的感到繁琐，这属实体力活呀！然而，自从有了Mybatis-Plus，自动生成代码，公司就再也不需要我这个fw了，哭唧唧~~

下面是在JDK21环境、maven3.6.3、SpringBoot3.x更新的代码生成器。

3. 创建单元测试类com.hu.mybatisplus.MybatisplusGeneratorApplicationTests

 @Testvoid testGenerator() {FastAutoGenerator.create("jdbc:mysql://127.0.0.1:3306/simpledemo?charactEncoding=UTF-8&serverTimezone=UTC", "root", "root")//1.全局配置.globalConfig(builder -> {builder.author("shunpeng.hu")
//                            .enableSwagger().fileOverride()  // 是否覆盖.outputDir("E:/study_code/mybatisplus-generator/src/main/java") // 设置生成路径.dateType(DateType.ONLY_DATE);})//2.包的配置.packageConfig(builder -> {builder.moduleName("generator").parent("com.hu.mybatisplus").entity("domain").mapper("mapper").service("service").serviceImpl("impl").controller("controller").pathInfo(Collections.singletonMap(OutputFile.xml, "E:/study_code/mybatisplus-generator/src/main/resources/mapper"));})//3.策略配置.strategyConfig(builder -> {builder.addInclude("tb_employee", "tb_department") // 设置要映射的表.addTablePrefix("tb_")  // 设置过滤表前缀.entityBuilder().enableLombok() // 自动lombok.naming(NamingStrategy.underline_to_camel).columnNaming(NamingStrategy.underline_to_camel).logicDeletePropertyName("deleted");  // 逻辑删除})//4.Freemarker引擎模板.templateEngine(new FreemarkerTemplateEngine()).execute();}

执行一下单元测试，就能有当前工程代码生成的模块~ 来吧，看看Freemarker模板引擎生成代码吧！
