搭建SpringBoot-MyBatis-MyBatisGenerator项目
搭建SpringBoot-MyBatis-MyBatisGenerator web 项目
以往使用tomcat下部署SSM项目, 习惯了老套路. 费尽一番周折终于把项目起来了, 当然这只是第一步…闲话少说进入正题:
问题1:相关jar包引入
jar包引入出错, 很可能会报各种class not found

问题2:generator工具的使用
对于generator插件的使用, 正确用法是(不是generator-source):
备注:用mybatis-generator时发现一个小的问题, 当修改generator.xml生成文件位置后, 最好删除原来已生成的相关文件, 有可能resultMap标签所指向的type文件位置并未改变, 此时会报**PO class not found
到此,可以生成dao层相关文件, 进行service层开发
问题3:启动一个spring boot工程
由于是ssm出身, 在使用的时候, 习惯性启动tomcat n次, 可是死活就是进不去controller, 输入url全是404.
痛定思痛仔细读相关资料, 这货类似纯java工程而非web项目, 启动的时候使用main方法, 同理debug…

怎么debug这货, 也是废了一番周折,在stackoverflow上找到答案, 瞬间感觉自己智商为0…
因为我以前debug的习惯是启动tomcat啊!!而这货不需要单独服务器部署..
以后开发继续跟进吧…
