com.mysql.jdbc.exceptions.jdbc4.Mysqlnontransientconnectionexception: No Operations allowed after Connection closed

Question

On my hosting service, whenever the time_out server arrives in 8 hours, gives this error:

com.mysql.jdbc.exceptions.jdbc4.Mysqlnontransientconnectionexception: No Operations allowed after Connection closed

After all queries I close the session, I take the connection of Hibernate do the query, populate the list and close the session with sessao.close().

I’ve done a lot of research and I see two different opinions on the subject:

• One of them, put autoconnect=true, just as,

  jdbc:mysql:/127.0.0.1:3306/seubanco? autoReconnect=true

• And in another, put the time_out 28800 milliseconds server for a higher value.

I’m very confused about this. What you think is the best option?
