(二)基於SSM+Redis+Nginx+FastDFS的部落格網站
阿新 • • 發佈:2018-11-03
上一篇簡單介紹了該網站的所用的框架、技術之類,這篇就開始講搭建過程。本篇為配置檔案。
其中redis和fastdfs的後續用到時再寫。
service層
PS:本篇總結,主要是配置SSM整合所需的檔案,都是很基礎的東西,沒什麼難點,檔案裡的配置也都有相關的註釋。 下一篇講的是登入模組,登入模組的話涉及到過濾器,在第一篇時,初始進入頁面,如果沒登入的話就會有遮罩層, 這個就是通過過濾器和前端的js程式碼實現的。
一、搭建基礎框架SSM之配置檔案
- maven工程的pom.xml,基本的SSM框架所需的Jar包,Jedis客戶端包,上傳元件,FastDFS包這個在maven庫裡是沒有的,需要自行下載然後新增到本地倉庫在進行maven更新。若maven更新後,jar包和配置檔案都有,但是啟動報錯,這時就該考慮是否是jar包衝突檔案。jar包衝突問題樓主也不怎麼會解決,如果是本地測試又比較趕時間的話,最簡單粗暴的方法是直接建立一個新的maven倉庫,也就是新建一個目錄,然後在ide的maven指向一下,再重新maven更新即可。

配置applicationContext-*.xml、springmvc.xml和web.xml檔案。在配置spring相關的配置檔案時,要切記spring分為父容器和子容器之分。子容器可以訪問父容器,而父容器不可以訪問子容器。在該系統中,application*.xml檔案都是父容器,而springmvc是子容器,所以controller層可以通過註解得到service層等的bean,而service層不能註解controller的bean<project
