JDBCExceptionReporter:78 - Data sources against establishment of connection, information from services: “Too many connections”

帮助我解答上述问题。

最佳回答
  1. Make sure you close the session (and connection) after using it
  2. Make sure the maximum connection configured for mysql is sufficient
  3. Use of some caching layer. It is insane to hit the database every 1 second from each user.
  4. If you are making some chat application, consider comet and server-side pub-sub solutions (jmx for example).
