我配置属性文件如下，可以正常使用单元测试获取数据查询：
# =============Database config==================
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/piratedmovie?allowPublicKeyRetrieval=true&useSSL=false
spring.datasource.username=root
spring.datasource.password=123456_
spring.datasource.hikari.maximum-pool-size=5
# ==============JPA / HIBERNATE=================
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
spring.jpa.generate-ddl=true
spring.main.web-application-type=none
logging.level.com.zaxxer.hikari.HikariConfig=DEBUG
logging.level.com.zaxxer.hikari=TRACE
我还根据许多人的建议添加了 spring-boot-starter-web、HikariCP、spring-boot-starter-data-jpa，但无法解决此问题。
任何人都可以为我提供解决方案来解决此问题。 谢谢
【问题讨论】：
【参考方案1】：当您指定 spring.main.web-application-type=none 时，您是在告诉 Boot 不要启动嵌入式 servlet 容器。因此，您的应用程序初始化并启动，然后关闭。注释掉这个属性，它应该开始暴露任何其他问题。

谢谢，但我之前尝试删除此行，但之后发生其他问题： org.springframework.context.ApplicationContextException: Unable to start web server;嵌套异常是 org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean。 你能展示你的“主要”课程吗？您的主类是否使用 @SpringBootApplication 注释？以上是关于如何在不启动 HikariPool 关闭的情况下使用 Hikari 数据源运行 Spring Boot 应用程序的主要内容，如果未能解决你的问题，请参考以下文章
