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
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:
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

添加完后点击应用
一键生成
选择数据库表
右击选择EasyCode
选择第一个
注意看,目前可以看到我项目左右目录里面并没有什么代码~
选择项目工程模块,选择模块对应的包,选择你创建好的组名
选择单表,选择单表,第一次使用模板不要多表!!!!!!!
单表构建全选所有配置,侧面按照我选的来选就行,下面我会讲解,因为这里有 Bug
点击确定之后可以看到我左侧项目目录代码已经生成完毕了~
接下来如果你想多表创建就可以这样选择,不需要在选择applicationYAML&interceptor类&R类&handler配置类了
配置
因为本人技术有限,有些地方还是会有一点小 Bug
如下图所示:在生成的文件里面会发现有 handler 处理类 interceptor 拦截器 util 工具类都相应的爆红了~
不要慌,这里的原因很简单,解决方案也就更很简单了
把文件名修改更 class 类名一直就欧克了
然后修改 applicationYml 文件,把你数据库名修改一下,账号密码修改一下,就可以跑了~
去 man 访问一下~
分页查询一下 200OK 没问题,
其余的自己测试,这里就不多做阐述了~
注意:Bug!!!!
在项目第一次使用模板的时候建议先单表生成,因为applicationYAML&interceptor类&R类&handler配置类都只需生成一次,如果你多表一次性全部全选,就会创建多个applicationYAML&interceptor类&R类&handler配置类,到时候出事就别说我没提醒~
如有更好的建议,可以在下面留言反馈~
