Spring HikariCP连接在点击10次后超时

我最近升级到SpringBoot 2.0.2.0版本。默认连接池已从Tomcat移动到HikariCP。我已将application.properties更改如下

spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=10
spring.datasource.hikari.idleTimeout=20000
spring.datasource.hikari.poolName=CoffeeHikariCP
spring.datasource.hikari.maxLifetime=1800000
spring.datasource.hikari.connectionTimeout=30000
spring.jpa.open-in-view=false

我正在使用standard Crudepository在Oracle DB上运行。我已经构建了一个示例控制器来从数据库中获取数据。点击10次后，报告以下错误，tha后不执行任何查询。如果我在设置中遗漏了什么，请告诉我。使用1.5.10时，一切正常
