二、項目配置文件application.yml

server:
  port: 8086
#FreeMarker
pring:
  freemarker:
    allow-request-override: false
    cache: false
    check-template-location: true

       url: jdbc:mysql://127.0.0.1:3306/springBootDemo
       username: root
       password: root
       # 使用druid數據源

mybatis:
  mapper-locations: classpath:mapping/*.xml
  type-aliases-package: com.winter.model
 
 
#pagehelper分頁插件
pagehelper:
  helperDialect: mysql
  reasonable: true
  supportMethodsArguments: true
  params: count=countSql
 
 
##上傳圖片保存的路徑
#img:
#  location: /Downloads/imgUpload/
 
#配置上傳文件的最大值
servlet:
  multipart:
    max-file-size: 5Mb
    max-request-size: 50Mb
 
#自定義文件上傳路徑
web:
  upload-path: /Downloads/imgUpload/

三、項目說明

1、項目默認將圖片上傳到本地路徑，如果需要上傳到服務器路徑直接在項目中進行修改即可，不要忘了修改存儲到數據庫中的路徑。

2、項目沒有使用任何圖片上傳控件或插件，原生springBoot實現，簡單易上手。

3、項目使用Maven進行構建，朋友們在導入項目時不要導錯了。
