??本文小博將寫一篇IDEA創(chuàng)建SSM+Maven整合項(xiàng)目,并提交至Github的教程惠桃。較為基礎(chǔ)浦夷,大神勿噴辖试。原創(chuàng)博客,轉(zhuǎn)載請注明來源劈狐。
步驟如下:
①新建Maven項(xiàng)目罐孝,如下圖順序。第三張圖片中肥缔,添加一個(gè)參數(shù)archetypeCatalog=internal莲兢,表示僅使用內(nèi)部元數(shù)據(jù),不用這個(gè)參數(shù)創(chuàng)建Maven項(xiàng)目會很慢哦续膳。其他起名字什么的大家大家隨意改艇,就不一一解釋了。
②將Java文件夾標(biāo)記為源碼目錄姑宽,然后創(chuàng)建各種MVC模式對應(yīng)的包
③如下圖遣耍,創(chuàng)建配置文件闺阱,然后進(jìn)行各種配置文件的編寫炮车。后面貼出我的代碼,篇幅太大就不逐一解釋了,以后有時(shí)間再詳細(xì)拉出來寫寫。
