Spring boot REST服务在一段时间后停止

Question

触发spring boot REST服务后，该服务可以正常运行数小时，所有请求都可以正常工作，没有任何问题。发生的是，一段时间后，它随机地停止了。在查看日志时，我没有发现任何错误，除了应用程序已被销毁的信息。

一段时间后的日志

对于为什么spring boot REST API可能会停止有什么想法吗？我的maven依赖关系是根据演示的--而且它正在成功运行--这就是为什么服务在随机时间后停止的原因，这是没有意义的。

用于Spring Boot的日志记录设置是

logging.level.org.springframework.web = DEBUG
logging.level.org.hibernate = ERROR
logging.file = /home/REST/Logging.log

Answer 1

根本原因是我与MySQL的连接停顿

spring.xxx.datasource.testOnBorrow=true
spring.xxx.datasource.validationQuery=SELECT 1
