二、项目配置文件application.yml

server:
  port: 8086
#FreeMarker
pring:
  freemarker:
    allow-request-override: false
    cache: false
    check-template-location: true
    charset: UTF-8
    content-type: text/html
    expose-request-attributes: false
    expose-session-attributes: false
    expose-spring-macro-helpers: false
    suffix: .ftl
spring:
    datasource:
       name: test
       url: jdbc:mysql://127.0.0.1:3306/springBootDemo
       username: root
       password: root
       # 使用druid数据源
       type: com.alibaba.druid.pool.DruidDataSource
       driver-class-name: com.mysql.jdbc.Driver
       filters: stat
       maxActive: 20
       initialSize: 1
       maxWait: 60000

       validationQuery: select 'x'
       testWhileIdle: true
       testOnBorrow: false
       testOnReturn: false
       poolPreparedStatements: true
       maxOpenPreparedStatements: 20
 
 
mybatis:
  mapper-locations: classpath:mapping/*.xml
  type-aliases-package: com.winter.model
 
 
#pagehelper分页插件
pagehelper:
  helperDialect: mysql
  reasonable: true
  supportMethodsArguments: true
  params: count=countSql
 
 
##上传图片保存的路径
#img:
#  location: /Downloads/imgUpload/
 
#配置上传文件的最大值
servlet:
  multipart:
    max-file-size: 5Mb
    max-request-size: 50Mb
 
#自定义文件上传路径
web:
  upload-path: /Downloads/imgUpload/

三、项目说明

1、项目默认将图片上传到本地路径，如果需要上传到服务器路径直接在项目中进行修改即可，不要忘了修改存储到数据库中的路径。

2、项目没有使用任何图片上传控件或插件，原生springBoot实现，简单易上手。

3、项目使用Maven进行构建，朋友们在导入项目时不要导错了。
