Question

我有一个带有oauth2安全性mySql数据库连接和一些控制器的spring boot应用程序。我已经将其部署在AWS服务器上，它可以正常工作，但是一段时间后它关闭，并且没有收到太多API调用，因此没有理由导致DDOS失败或内存不足错误，我可以在日志中看到以下消息

2018-10-28 10：58：55.979信息1253 --- [Thread-3] ConfigServletWebServerApplicationContext：关闭org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@3ac42916：启动日期[Sun Oct 28 08： 46:01 UTC 2018]；上下文层次结构的根 2018-10-28 10：58：55.983信息1253 --- [Thread-3] o.s.c.support.DefaultLifecycleProcessor：在阶段2147483647中停止bean 2018-10-28 10：58：55.985信息1253 --- [Thread-3] o.s.j.e.a.AnnotationMBeanExporter：关闭时注销JMX暴露的bean 2018-10-28 10：58：55.986信息1253 --- [Thread-3] o.s.j.e.a.AnnotationMBeanExporter：注销JMX暴露的bean 2018-10-28 10：58：55.993信息1253 --- [Thread-3] j.LocalContainerEntityManagerFactoryBean：关闭持久性单元'default'的JPA EntityManagerFactory 2018-10-28 10：58：55.994信息1253 --- [Thread-3] com.zaxxer.hikari.HikariDataSource：HikariPool-1-关闭启动... 2018-10-28 10：58：56.002信息1253 --- [Thread-3] com.zaxxer.hikari.HikariDataSource：HikariPool-1-关闭已完成。

这是我的应用。属性

spring.datasource.username = xxx
spring.datasource.password = xxx
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto = validate
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
spring.jackson.serialization.fail-on-empty-beans=false
logging.level.org.springframework.security=DEBUG

logging.path = logs / core /

Spring Boot应用程序运行一段时间后会关闭
