在自由运行应用程序时运行负载测试，并通过JNDI从自由获取数据源时，测试在大约一分钟后失败，但以下情况除外：
由以下原因引起：org.springframework.jdbc.CannotGetJdbcConnectionException：无法获取JDBC连接。嵌套的异常是java.sql.SQLTransientConnectionException：J2CA0045E：为资源jdbc / MY_JNDI_NAME调用方法createOrWaitForConnection时，连接不可用。超时等待30,000毫秒，剩余29个等待请求和10个当前使用的连接。
直接在spring-application中配置数据源（并因此使用HikariCP作为连接池）时，同一测试成功运行了10分钟。
已尝试从应用程序中排除hikaricp依赖项，以确保hikari不会以某种方式涉及自身。
edit1： 进行相同的呼叫时似乎有一些不同的行为。从春季开始（执行commit和afterCommit）：

这是来自自由的同样呼吁：

两个调用均以TransactionSynchronizationManager删除数据源上键入的值结束
