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,一种是码解直播源码平台优势HikariPool自带的,具体逻辑没看,码解如果没适配对应的码解商城菜单源码下载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,码解商城文章系统源码Outofbox,码解是码解指在开发过程中,通过在MAVEN项目的muedit 易语言源码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。xscript脚本源码
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。
