jrebel-mybatisplus 下載地址 ,然后在git命令窗依次執行以下命令:
1 git clone */jrebel-mybatisplus.git 2 cd jrebel-mybatisplus 3 mvn -f pom.xml clean package
將構建好的插件jrebel-mybatisplus\target\jr-mybatisplus-*.jar拷貝至任意目錄dir
修改運行配置,增加VM參數:-Drebel.plugins=dir\jr-mybatisplus-*.jar,然后以JRebel方式啟動
修改你項目中的mapper xml 文件后,重新編譯,如果重新請求接口,你應該會看到控制台輸出 “Reloading SQL maps”
