spring-boot - 配置 hikaricp 和 spring boot 时出现“无法确定合适的驱动程序类”异常
问题描述
仅使用位于资源目录中的application.properties文件配置 hikaricp 。
application.properties内容：
spring.datasource.url=jdbc:mysql://localhost/torquejobqa_db
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.hikari.username=dev0
spring.datasource.hikari.password=123456
spring.datasource.hikari.max-lifetime=1800000
“build.gradle”内容：
/*
* This file was generated by the Gradle 'init' task.
*
* This is a general purpose Gradle build.
* Learn how to create Gradle builds at https://guides.gradle.org/creating-new-gradle-builds

我遵循了这个Spring Boot Features doc，Hikaricp Configuration并得到了这个异常。我做错什么了吗？
解决方案
对不起，我没有在问题描述中添加一些额外的信息。
这是一个在 servlet 容器 Jetty 中运行的 Web 应用程序。这个 gradle 项目旨在打包为传统的可部署战争文件。
似乎application.propertiesSpring Boot 根本没有检测到该文件。
解决方案：我根据https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file让我的 @SpringBootApplication 注释类扩展 SpringBootServletInitializer 。SpringBootServletInitializer 将注册 DispatcherServer 并为 ContextLoaderListener 配置根 ApplicationContext。
