Broken Pipe - Socket Exception - with latest version of Hibernate - spring

Question

I didn't expect to see this even using the latest version of Hibernate. I am using Hibernate version 5.1.0.Final
I am using it with spring and here is the config:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
p:dataSource-ref="mySQLDataSource">
<property name="packagesToScan" value="package.to.scan"/>
<property name="hibernateProperties">
<props>
<prop key="showSql">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
</props>
</property>
</bean>
The mySQLDataSource bean:
<bean id="mySQLDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/dbResource"/>
</bean>
The JNDI resource:
<Resource name="jdbc/dbResource"
auth="Container"
type="javax.sql.DataSource"
maxActive="50"
username="root"
password=""
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/dbname"
/>
There is probably a workaround this but I am really interested in knowing what is the standard approach to resolve this problem?

Answer 1

Looks like this issue is happening if the application has no activity with the database for a considerable amount of time (say 12 hours in your case). So it could be an issue related to expired or stale connection issue.
As per this link, MySQL by defaults assumes any connection that has been idle for a longer period, say 8 hours, marks it as inactive and closes it. But the connection pooling mechanism on application end may not be aware of this connection close and results in broken pipe exception at a later point when the app actually uses it.
As suggested in the link please set up with testOnBorrow=true and validationQuery=SELECT 1.
Apart from that, your sessionFactory is still using hibernate4 specific one.
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
I believe that could be the issue.
Can you try with hibernate5 specific LocalSessionFactoryBean.
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"
