我们已经在tomcat服务器上制作了一个rest spring boot spring数据应用程序。该应用程序可以在本地环境中工作。但是，当部署到生产环境中时，该应用程序在并发命中之后会给出以下异常。
例外： 错误org.hibernate.engine.jdbc.spi.SqlExceptionHelper-HikariPool-1-连接不可用，请求在30004ms后超时。 javax.persistence.PersistenceException：
org.hibernate.exception.JDBCConnectionException：无法获取JDBC连接
原因：org.hibernate.exception.JDBCConnectionException：无法获取JDBC连接
该应用程序被部署为apache tomcat中的war文件，将单个数据源连接到oracle
配置如下：- application.properties如下：-

请检查配置并提供解决方案， HikariCP之前可能与服务器关闭连接有关，但是我不确定。任何对此的评论将不胜感激。
