由于沒理解servlet為何要用struts2取代而耗費了不少時間在找如何獲取前端傳輸過來的數據。html

public void doPost(HttpServletRequest request,HttpServletResponse esponse) throws IOException,ServletException而轉為struts2時，struts2給咱們處理了。

因此你須要在Action中定義他們，并且要和前端對應。

以上基本是主要的，數據庫

struts2.xml配置struts2apache

/WEB-INF/jsp/user.jsp

applicationContext.xml配置Springtomcat

scope="prototype">

只是個人理解，本文章只做我的工做記錄，但愿不要誤導后來人。服務器

有些內容沒有用到，等過幾天再改一下，會添加用戶的數據庫內容。app

總結

以上是生活随笔為你收集整理的服务器文件上传记录,记录一下上传文件（图片）的过程上传图片到ftp服务器的全部內容，希望文章能夠幫你解決所遇到的問題。
