数据库连接自动断开重连不上

凡事总要有信心，老想着“行”。要是做一件事，先就担心着"怕咱不行吧”，那你就没有勇气了。——盖叫天

今天报了这么一个错

数据库连接不上了，重连也失败，超时

解决办法：

加上hikari配置

spring:
  # 数据源配置
  datasource:
    hikari:
      connection-test-query: SELECT 1 FROM DUAL
      connection-timeout: 600000
      maximum-pool-size: 500
      max-lifetime: 1800000
      minimum-idle: 20
      validation-timeout: 3000
      idle-timeout: 60000
      connection-init-sql: SET NAMES utf8mb4
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: ruben
    password: rubenFoolish
    url: jdbc:mysql://localhost:3306/ruben?autoReconnect=true&zeroDateTimeBehavior=CONVERT_TO_NULL&useUnicode=true&characterEncoding=utf-8&useSSL=false&nullCatalogMeansCurrent=true&serverTimezone=Asia/Shanghai&allowMultiQueries=true&allowPublicKeyRetrieval=true
