public boolean shouldExceptionTriggerFailover(Throwable ex)

从接口复制的说明: LoadBalanceExceptionChecker

Invoked to determine whether or a given SQLException should trigger a failover in a load-balanced deployment. The driver will not pass in a Connection instance when calling init(), but it will pass in the Properties, otherwise it acts like a normal Extension. One instance of a handler *per* JDBC connection instance will be created. If you need singleton-like behavior, you're on your own to provide it.

指定者:

shouldExceptionTriggerFailover 在接口中 LoadBalanceExceptionChecker

覆盖:

shouldExceptionTriggerFailover 在类中 StandardLoadBalanceExceptionChecker

参数:

ex - exception

返回:

true if the exception should trigger failover.
