Hibernate 4 default transaction timeout value
提问by Tobia
I'm getting this error:
我收到此错误：
2014-11-14 17:39:44 [WARN]SqlExceptionHelper:143 SQL Error: 0, SQLState: 08S01
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.
2014-11-14 17:39:44 [ERROR]BackupService:245 org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.JDBCConnectionException: Could not open connection
Seems that Hibernate has a small transaction timeout for my job, but I can not find what is the default timeout value. I did not find it also in hibernate documentation, I find how to change it, but not the default value.
似乎 Hibernate 对我的工作有一个小的事务超时，但我找不到默认超时值是多少。我也没有在 hibernate 文档中找到它，我找到了如何更改它，但没有找到默认值。
This is my hibernate configuration:
这是我的休眠配置：
<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>
Do you know what is the default timeout value for an hibernate transaction with this configuration?
您知道具有此配置的休眠事务的默认超时值是多少吗？

I got the same exception. I googled and found your question without answer :)
我得到了同样的例外。我用谷歌搜索，发现你的问题没有答案:)
I changed "Timeout Seconds:" from 300 to 1000 (possible to increase more, it depends on your transaction timeout) on "mydomain->Configuration->JTA" on Weblogic Console or increase JTA timeout on your application server.
我在 Weblogic 控制台上的“mydomain->Configuration->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），或者在您的应用程序服务器上增加 JTA 超时。
Then, for hibernate.cfg.xml you may check this answer: Hibernate/MySQL Connection Timeout
然后，对于 hibernate.cfg.xml 你可以检查这个答案：Hibernate/MySQL Connection Timeout
It works.
有用。
