項(xiàng)目搭建就不重復(fù)說(shuō)了，有不明白的請(qǐng)參考 Maven+Eclipse（STS）搭建SSM項(xiàng)目筆記： http://www.reibang.com/p/ca0e929c180a。

使用SSM項(xiàng)目測(cè)試問(wèn)題苹丸，每次啟動(dòng)容器測(cè)試數(shù)據(jù)層沐悦，業(yè)務(wù)層代碼有點(diǎn)麻煩涎显。使用Junit單元測(cè)試可以解決每次測(cè)試數(shù)據(jù)層摧茴，業(yè)務(wù)層哄褒，控制層的代碼測(cè)試稀蟋。直接上代碼。

是不是很方便呀呐赡！如果幫到了你退客，麻煩老鐵點(diǎn)贊！謝謝各位链嘀。
