MyBatis-Plus代码生成器

该生成器是基于 springboot 2.5.0 + maven + jdk8 环境

• 创建 springboot + maven 项目
• 在pom中引入依赖
• 编写代码生成器

                            .columnNaming(NamingStrategy.underline_to_camel)//表字段映射实体属性命名规则：默认null，不指定按照naming执行
                            .idType(IdType.AUTO)//添加全局主键类型
                            .formatFileName("%s")//格式化实体名称，%s取消首字母I,
                            .mapperBuilder()
                            .enableMapperAnnotation()//开启mapper注解
                            .enableBaseResultMap()//启用xml文件中的BaseResultMap 生成
                            .enableBaseColumnList()//启用xml文件中的BaseColumnList
                            .formatMapperFileName("%sMapper")//格式化Dao类名称
                            .formatXmlFileName("%sMapper")//格式化xml文件名称
                            .serviceBuilder()
                            .formatServiceFileName("%sService")//格式化 service 接口文件名称
                            .formatServiceImplFileName("%sServiceImpl")//格式化 service 接口文件名称
                            .controllerBuilder()
                            .enableRestStyle();
                })
                //.templateEngine(new FreemarkerTemplateEngine()) //使用Freemarker模版引擎
                .execute();
    }
}

说明：默认使用的是Velocity模板引擎，如果想要指定Freemarker模板引擎，则只需要将velocity依赖改为freemarker依赖，并且在生成代码时指定Freemarker即可
