How to Troubleshoot and Resolve MySQL Communication Failures in Java Applications?

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure Software caused connection abort: recv failed

MySQL communication failures can arise due to a timeout between the Java application and the MySQL server. One possible solution is to increase the MySQL timeout by modifying the configuration file (my.ini). Additionally, reducing the idle time in the connection pool ensures that the pool discards connections before MySQL closes them. Lastly, adding a validate connection query to the pool configuration allows the pool to test connections before providing them, although this approach may introduce performance implications.
