需求：實現圖片的上傳和批量上傳

技術：Nginx，Vsftpd，Spring，SpringMVC，KindEditor，CentOS

說明：本章節內容主要是實現圖片的上傳功能。使用 KindEditer 是為了更好的演示圖片的上傳，回顯，批量效果。后臺代碼與KindEditer沒有直接關系，放心閱讀。另外源碼中有Mybatis的jar，不用理會，本章內容用不到，是為后續內容做準備！

源碼：見文章底部

場景：用戶將圖片上傳到 tomcat 服務器上，再由 tomcat 服務器通過FTP上傳到 Nginx 服務器上。

項目結構：

單元測試

首先要攻破核心技術。通過單元測試實現圖片上傳的功能。

package com.itdragon.test;import java.io.File;import java.io.FileInputStream;import org.apache.commons.net.ftp.FTP;import org.apache.commons.net.ftp.FTPClient;import org.junit.Test;public class PictureFTPTest {  // 測試 ftp 上傳圖片功能  @Test  public void testFtpClient() throws Exception {    // 1. 創建一個FtpClient對象    FTPClient ftpClient = new FTPClient();    // 2. 創建 ftp 連接    ftpClient.connect("192.168.0.11", 21);    // 3. 登錄 ftp 服務器    ftpClient.login("ftpuser", "root");    // 4. 讀取本地文件    FileInputStream inputStream = new FileInputStream(new File("F://hello.png"));    // 5. 設置上傳的路徑    ftpClient.changeWorkingDirectory("/usr/local/nginx/html/images");    // 6. 修改上傳文件的格式為二進制    ftpClient.setFileType(FTP.BINARY_FILE_TYPE);    // 7. 服務器存儲文件，第一個參數是存儲在服務器的文件名，第二個參數是文件流    ftpClient.storeFile("hello.jpg", inputStream);    // 8. 關閉連接    ftpClient.logout();      }  }

說明：這里的ip地址，端口，ftp用戶名，密碼，本地文件路徑，以及Nginx服務器圖片路徑等，這些字符串參數都要根據自己實際設置的來填寫的。如果你的Nginx和Vsftpd安裝是按照我提供的鏈接來做的。那你只需要改ip地址即可。

Maven 的Web 項目

搭建Maven的Web 項目，之前有寫過。這里就不過多描述。

項目核心配置文件

首先是 Maven 的核心文件 pom.xml
