建立項目
建立maven project
三者全部勾選,
第一個是:建立一個簡單的maven工程
第二個是:選擇存儲路徑,隻要選擇預設即可
第三個是:選擇工作區,自己随便建立一個 即可
然後一路finsh 直到建立完成即可
如果建立出來的程式有錯誤,可以右鍵項目->選擇java ee tools ->點選 generate deployment…這個選項即可
檢視webapp是否格式如下
如果不是,則右鍵項目->選擇properties->選擇project facets
先取消紅框的地方,在勾選那個紅框
在彈出的地方進行修改如下 :
修改紅框内容如下即可
然後配置pom.xml檔案
maven工程的一個好處就是無需在自行下載下傳導入jar包,而是直接在pom.xml檔案寫上需要導入的檔案即可完成導入
源碼如下

然後配置ssm相關的三個配置
其中applicationContext.xml如下

在配置好ssm的xml檔案之後,需要在相應項目的web.xml配置,即每次登入相應網頁,項目會按照web檔案的配置去掃描相應的ssm檔案,是以如果報錯某個ssm配置檔案沒有掃描到,就要排查是否是你的檔案名字或者路徑配置錯誤了!
web.xml
