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

 @Test
    void 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！
