org.apache.tomcat.jdbc.pool.ConnectionPool - 无法使用yml文件创建池的初始连接

时间:2023-01-14 23:58:22

sorry for the long error log. I'm at my wits end, im upgrading an old app from 2.2.2 to 3.1.2 and i really need help.

抱歉长错误日志。我在我的智慧结束,我将旧的应用程序从2.2.2升级到3.1.2,我真的需要帮助。

tried to apply datasource.groovy to application.yml

试图将datasource.groovy应用于application.yml

hibernate:

    queries: false
    use_second_level_cache: true
    use_query_cache: false
    region.factory_class: 'org.hibernate.cache.ehcache.EhCacheRegionFactory'

dataSource:

jmxExport: true
driverClassName: com.mysql.jdbc.Driver

            testOnBorrow: true
            testWhileIdle: true
            testOnReturn: false
            jdbcInterceptors: ConnectionState
            defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED

after doing so, run-app doesn't work and these are what appeared amongst others. any help will be greatly appreciated.

在这样做之后,run-app不起作用,这些都出现在其他人之间。任何帮助将不胜感激。

This is what's been happening so far

这是到目前为止发生的事情
