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
我还添加了许多人建议的 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
解决方案
当您指定时，spring.main.web-application-type=none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。
