在我的 spring boot 2.3 应用程序中，我正在连接到 Oracle DB，但是我每 10 分钟左右就会遇到一次连接问题。我不知道为什么总数总是 1
这是我的连接详情
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.idle-timeout=10000
spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=50
spring.datasource.hikari.idleTimeout=30000
spring.datasource.hikari.maxLifetime=2000000
spring.datasource.hikari.connectionTimeout=30000
spring.datasource.hikari.leak-detection-threshold=15000
spring.datasource.hikari.poolName=DeGPool
这是我的调试日志
