从接口复制的说明: BalanceStrategy

Called by the driver to pick a new connection to route requests over. See LoadBalancedConnectionProxy.createConnectionForHost(String)

指定者:

pickConnection 在接口中 BalanceStrategy

覆盖:

pickConnection 在类中 RandomBalanceStrategy

参数:

proxy - the InvocationHandler that deals with actual method calls to the JDBC connection, and serves as a factory for new connections for this strategy via the createConnectionForHost() method. This proxy takes care of maintaining the response time list, map of host/ports to live connections, and taking connections out of the live connections map if they receive a network-related error while they are in use by the application.

configuredHosts - the list of hosts/ports (in "host:port" form) as passed in by the user.

liveConnections - a map of host/ports to "live" connections to them.

responseTimes - the list of response times for a transaction for each host in the configured hosts list.

numRetries - the number of times the driver expects this strategy to re-try connection attempts if creating a new connection fails.

返回:

the physical JDBC connection for the application to use, based upon the strategy employed.

抛出:

SQLException - if a new connection can not be found or created by this strategy.
