driver does not support get/ set network timeout for connections什么意思?
Driver does not support get/set network timeout for connections错误的码解原因:pringboot 2.x默认的数据源变成了HikariPool了,弄了一个demo在使用数据源的码解时候系统报错 HikariPool-1 - Driver does not support get/set network timeout for connections. (null)。具体的码解解决办法:通过源码排查到连接验证有两种方式,一种是码解弹出div源码HikariPool自带的,具体逻辑没看,码解如果没适配对应的码解直播交友软件app源码驱动就会报上面的错误;另一种是使用ConnectionTestQuery 这个属性来验证。那行代码大概就是码解:boolean isUseJdbc4Validation = getConnectionTestQuery == null;
如果这个属性没有配置,则使用默认的码解,若配置了,码解则使用自行配置的码解。所以只需要配置一下测试脚本即可。码解
扩展资料:
SpringBoot框架:
SpringBoot框架中还有两个非常重要的码解策略:开箱即用和约定优于配置。开箱即用,码解原图君小程序源码Outofbox,码解是码解指在开发过程中,通过在MAVEN项目的嵌入式源码树pom文件中添加相关依赖包,然后使用对应注解来代替繁琐的XML配置文件以管理对象的生命周期。这个特点使得开发人员摆脱了复杂的配置工作以及依赖的管理工作,更加专注于业务逻辑。金龙波段指标源码公式
约定优于配置,Convention over configuration,是一种由SpringBoot本身来配置目标结构,由开发者在结构中添加信息的软件设计范式。这一特点虽降低了部分灵活性,增加了BUG定位的复杂性,但减少了开发人员需要做出决定的数量,同时减少了大量的XML配置,并且可以将代码编译、测试和打包等工作自动化。
