写在前面的话: 本脚本模板不收取任何费用,初衷就是不想重复造梯子,如果对各位有帮助的话,可以给作者打上一杯奶茶钱,目前插件还是有点小 Bug,但是不影响使用,现在各平台相关的代码生成插件也比较成熟了,并且带有独特的特色和一些自带的代码提示功能,使用感受整体都不错,但是好用的插件肯定是要收费的啦~具体的请参考下面相关插件查看

查看视频教程

参考插件
MyBatisCodeHelper-Pro
codehelper.generator
mybatis
mybatis generator
pageHelper
mybatis-generator-gui
mybatis generator plugin
mybatisplus

功能介绍

本脚本只适用于 EasyCode 模板搭配使用

支持生成代码具体如下:

controller 层代码

handler 处理器

interceptor 拦截器

mapper 数据库接口

pojo 实体类

service 服务层

service-impl 服务层实现类

application.yaml yaml全局配置文件

Bug修复~

是不是很方便,一键生成到底,基本满足你日常 CRUD

虽然还是有点 Bug,但是我觉得他已经成熟了,因为不影响使用,具体 Bug 我会在下文中讲些

使用教程

前置条件

随意创建一个 SpringBoot 项目,在 pom 里面引入相关依赖

<!--mp-->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.5.1</version>
</dependency>
<!--Mysql驱动-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
<!--mp代码生成器-->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.5.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.alibaba/druid-spring-boot-starter -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.6</version>
</dependency>

搜索 EasyCode 插件安装

在文件>设置>其他设置>EasyCode>Template 中添加组名,命名随意,可以看到,除了第一个,下面四个都插件自带的,你们也可以尝试一下

接下来就是最重要的添加模板了
