解决方法

我们查看数据库的HikariPool源码

找到HikariDataSource类，他继承了HikariConfig

我们看Hikar的相关配置，进入HikarConfig中，在这里我们可以看到默认池大小为10，我们在数据库配置中修改默认池大小即可解决问题

配置文件中加入

• minimum-idle最小空闲数
• maximum-pool-size链接池最大数量
• max-lifetime最大时长，配置为0则是永久不过期

    hikari:
      minimum-idle: 3
      maximum-pool-size: 5
      max-lifetime: 0

修改过配置文件后即可解决问题

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
