Hibernate c3p0 Configuration

Hibernate was used in the project. Later, the connection was automatically disconnected when MySQL was idle for 8 hours. In this way, the s3p0 connection pool was used to try. Which of the following errors still persists:

Com. mchange. v2.resourcepool. basicresourcepool $ asynctestidleresourcetask run

Specified resource usage: basicresourcepool: An idle resource is broken and will be purged. java. SQL. sqlexception: communication link failure: java.net. socketexception, underlying cause: Software caused connection abort, record it and back it up on your own. At the same time, I hope to give a reference to my friends who have encountered the same problem.

<Property name = "show_ SQL"> false </property> <property name = "hibernate. connection. provider_class "> Org. hibernate. connection. c3p0connectionprovider </property> <property name = "hibernate. c3p0. min_size "> 8 </property> <property name =" hibernate. c3p0. max_size "> 200 </property> <property name =" hibernate. c3p0. timeout "> 600 </property> <property name =" hibernate. c3p0. max_statements "> 0 </property> <property name =" hibernate. c3p0. idle_test_period "> 60 </property> <property name =" hibernate. c3p0. acquire_increment "> 2 </property> <property name =" hibernate. c3p0. validate "> true </property>: although the problem has been solved, I still don't quite understand why this configuration is implemented in some places. If you have any comments on this configuration, let's discuss it together.
