升级springboot版本从2.0.6到2.1.3遇到的坑

1.修改jdbc驱动类
1.1.将JDBC驱动类修改为
com.mysql.cj.jdbc.Driver
1.2.URL中添加时区信息
serverTimezone=Asia/Shanghai&

2.将spring.servlet.multipart.max-request-size和spring.servlet.multipart.max-file-size的单位全部变成大写100MB

3.添加依赖


    org.springframework.boot
    spring-boot-starter-actuator


    io.micrometer
    micrometer-registry-prometheus
    1.1.3


    io.micrometer
    micrometer-core
    1.1.3

4.application.yaml中添加
management:
  metrics:
    tags:
      application: ${spring.application.name}
  endpoints:
    web:
      exposure:
        include: "*"
