 1 | # 图片上传Demo
 2 | 
 3 | ### 思路
 4 | - 一般情况下都是将用户上传的图片放到服务器的某个文件夹中，然后将图片在服务器中的路径存入数据库。本Demo也是这样做的。
 5 | - 由于用户自己保存的图片文件名可能跟其他用户同名造成冲突，因此本Demo选择了使用UUID来生成随机的文件名解决冲突。
 6 | - 但是本Demo不涉及任何有关数据库的操作，便于演示，就用原来的文件名。
 7 | ### 准备工作
 8 | >文件名的生成 ( FileNameUtils )
 9 | - 不准备重新将用户上传的文件重新命名可以略过此步骤。
10 | ```
11 | package com.wu.demo.fileupload.demo.util;
12 | 
13 | public class FileNameUtils {
14 | 
15 |     /**
16 |      * 获取文件后缀
17 |      * @param fileName
18 |      * @return
19 |      */
20 |     public static String getSuffix(String fileName){
21 |         return fileName.substring(fileName.lastIndexOf("."));
22 |     }
23 | 
24 |     /**
25 |      * 生成新的文件名
26 |      * @param fileOriginName 源文件名
27 |      * @return
28 |      */
29 |     public static String getFileName(String fileOriginName){
30 |         return UUIDUtils.getUUID() + FileNameUtils.getSuffix(fileOriginName);
31 |     }
32 | 
33 | }
34 | 
35 | ```
36 | 
37 | ### 文件上传
38 | 
39 | ```
40 | package com.wu.demo.fileupload.demo.util;
41 | 
42 | import org.springframework.web.multipart.MultipartFile;
43 | 
44 | import java.io.File;
45 | import java.io.IOException;

57 |      * @return
58 |      */
59 |     public static boolean upload(MultipartFile file, String path, String fileName){
60 | 
61 | 
62 |         // 生成新的文件名
63 |         //String realPath = path + "/" + FileNameUtils.getFileName(fileName);

66 |         String realPath = path + "/" + fileName;
67 | 
68 |         File dest = new File(realPath);
69 | 
70 |         //判断文件父目录是否存在
71 |         if(!dest.getParentFile().exists()){
72 |             dest.getParentFile().mkdir();
73 |         }
74 | 
75 |         try {
76 |             //保存文件
77 |             file.transferTo(dest);
78 |             return true;
79 |         } catch (IllegalStateException e) {
80 |             // TODO Auto-generated catch block
81 |             e.printStackTrace();
82 |             return false;
