Question

我有一个汇总的数据源，可使用配置单元驱动程序与Impala数据库连接。我使用这样的配置：

spring:
    datasource:
        url: "jdbc:hive2://${impala.host}:${impala.port}/;auth=noSasl"
        username: "${impala.username}"
        password: "${impala.password}"
        driverClassName: org.apache.hive.jdbc.HiveDriver
        validation-query: select 1
        test-on-borrow: true
        test-while-idle: false

我多次收到此错误：

我不知道谁在关闭连接。您知道如何找出连接被关闭的原因吗？

感谢拉斐尔。

为什么与黑斑羚的连接被关闭？
