1、application.properties

也可使用yml yaml

#静态资源
spring.mvc.static-path-pattern=/images/**
#上传文件大小设置
spring.http.multipart.max-file-size=10MB
spring.http.multipart.max-request-size=10MB

spring.mvc.pathmatch.matching-strategy=ant_path_matcher

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/数据库名字
spring.datasource.username=root
spring.datasource.password=root
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

2、pom.xml

主要部分配置
