Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was59461 milliseconds ago.The last packet sent successfully to the server was 59461 milliseconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

您需要配置Hibernate使您的連接保持活着執行啞查詢。

<!--connection pool--> 
<property name="hibernate.dbcp.maxActive">10</property> 
<property name="hibernate.dbcp.whenExhaustedAction">1</property> 
<property name="hibernate.dbcp.maxWait">20000</property> 
<property name="hibernate.dbcp.maxIdle">10</property> 

<!-- prepared statement cache--> 
<property name="hibernate.dbcp.ps.maxActive">10</property> 
<property name="hibernate.dbcp.ps.whenExhaustedAction">1</property> 
<property name="hibernate.dbcp.ps.maxWait">20000</property> 
<property name="hibernate.dbcp.ps.maxIdle">10</property> 

<!-- optional query to validate pooled connections:--> 
<property name="hibernate.dbcp.validationQuery">select 1</property> 
<property name="hibernate.dbcp.testOnBorrow">true</property> 
<property name="hibernate.dbcp.testOnReturn">true</property>
