spring:
  datasource:
    url: jdbc:mysql://localhost:3306/book_manage
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver
    
  mvc:(如果html里的静态资源路径没有static就不需要像这样配置，只是这套模板路径有static比特殊)
    static-path-pattern: /static/**
  	
  mail:
  	host: smtp.163.com（邮箱网站的smtp）
  	username: 发送者用户邮箱
  	password: 邮箱开启smtp和pop功能后会返回一串密码
  	
  redis:(如果redis在本地则不需要配置)
  host:localhost:8080
