The reconnection mechanism is one of the specific manifestations of activemq's high availability.
Specifically, you can use the Failover method to connect to one or more brokerurls after the connection is disconnected.
For example: failover :( TCP: // 127.0.0.1: 61616). Multiple URLs can be used here.
By default, if the client and the broker are disconnected directly, the client starts a new thread,
Continuously obtain a URL from the URL parameter to retry the connection.
This mechanism has a pr

maintain the connection state.In summary, the choice of long connections and short connections is subject to availability.First, if you use a long connection and do not perform any operations on the database for a long time, after the timeout value, MySQL server closes the connection, and the client executes the query with an error similar to "MySQL server has gone away".After using Mysql_real_connect to connect to the database, use Mysql_options (mysql, Mysql_opt_reconnect, ...) to set it to a
