Question

我刚刚将Spring Boot应用程序（Spring Cloud Task）从1.5升级到2.0.0（Spring Boot），任务/应用程序中的作业运行得很好，但是在作业完成后jar无法关闭。它卡在这里：

2018-11-14 18:08:21.711  INFO 7720 --- [           main] o.s.b.c.l.support.SimpleJobLauncher      : Job: [SimpleJob: [name=testJob]] completed with the following parameters: [{-spring.batch.job.names=testJob, run.id=10}] and the following status: [COMPLETED]
2018-11-14 18:08:21.719 DEBUG 7720 --- [           main] o.s.c.t.r.support.SimpleTaskRepository   : Updating: TaskExecution with executionId=16 with the following {exitCode=0, endTime=Wed Nov 14 18:08:21 IST 2018, exitMessage='null', errorMessage='null'}

在键盘上按ctrl + c组合键后，HikariCP将关闭：

^C2018-11-14 18:08:25.738  INFO 7720 --- [       Thread-4] com.zaxxer.hikari.HikariDataSource       : HikariPool-1 - Shutdown initiated...
2018-11-14 18:08:25.740  INFO 7720 --- [       Thread-4] com.zaxxer.hikari.HikariDataSource       : HikariPool-1 - Shutdown completed.

我想在完成作业后立即关闭应用程序/ jar。

经过反复试验后，我意识到，当我在应用程序.yml中通过休眠模式删除对二级缓存的使用时，它可以正常工作，即，hikariCP在作业完成后关闭。这是我的application.yaml：

spring:
  application:
    name: miq-batch
  datasource:
    url: jdbc:mysql://localhost:3306/scdf
    username: root
    password: root
    driverClassName: org.mariadb.jdbc.Driver
  data:
    mongodb:
      host: localhost
      port: 27017
      database: profile      
  jpa:
    properties:
      hibernate:
        implicit_naming_strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyHbmImpl
        hbm2ddl:
          auto: update
        cache:
          use_second_level_cache: true
          region.factory_class: org.hibernate.cache.ehcache.EhCacheRegionFactory
          use_query_cache: true
          use_collection_cache: true
  jackson:
    serialization:
      FAIL_ON_EMPTY_BEANS: false

通过休眠使用二级缓存时，Hikari CP无法关闭
