我收到此错误:

2014-11-14 17:39:44 [ERROR]SqlExceptionHelper:144 Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

似乎Hibernate对我的作业有一个小的事务超时,但我找不到默认的超时值。我在hibernate文档中也没有找到它,我发现如何更改它,但不是默认值。
这是我的hibernate配置:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan">
<list>
<value>com.test.db.entity</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.bytecode.use_reflection_optimizer">false</prop>
<prop key="hibernate.cglib.use_reflection_optimizer">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.search.autoregister_listeners">false</prop>
<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>
</props>
</property>
</bean>
您知道具有此配置的hibernate事务的默认超时值是什么?
答案 0 :(得分:0)
我得到了同样的例外。我用谷歌搜索,发现你的问题没有回答:)
我在Weblogic控制台上的“mydomain-&gt; Configuration-&gt; JTA”上将“Timeout Seconds:”从300更改为1000(可能会增加更多,这取决于您的事务超时)或增加应用程序服务器上的JTA超时。
然后,对于hibernate.cfg.xml,您可以查看以下答案:Hibernate/MySQL Connection Timeout
有效。
