Question

在我的集成测试中启动服务时，我收到JDBC连接错误 -

Clearing pending acquires. While trying to acquire a needed new resource, we failed to succeed more than the maximum number of allowed acquisition attempts (30). Last acquisition attempt exception:

这是应用程序属性文件 -

dataSource.driverClassName=org.h2.Driver
dataSource.url=jdbc:h2:tcp://localhost:59000/./target/servicedatabase-db;MODE=Oracle;IGNORECASE=TRUE;IFEXISTS=TRUE
dataSource.username=sa
dataSource.password=sa
dataSource.maxActive=2
dataSource.initialSize=1
dataSource.maxIdle=1

我无法理解导致问题的原因。任何指针都表示赞赏。

在进行maven清洁验证时，测试运行良好，但不是单独进行。当时我们可以讨论这个话题。
