[英]Hibernate 4 default transaction timeout value
I'm getting this error: 我收到此错误:

Seems that Hibernate has a small transaction timeout for my job, but I can not find what is the default timeout value. 似乎Hibernate对我的工作来说有一个小的事务超时,但是我找不到默认的超时值。 I did not find it also in hibernate documentation, I find how to change it, but not the default value. 我也没有在休眠文档中找到它,我找到了如何更改它,但是没有更改默认值。
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? 您知道使用此配置的休眠事务的默认超时值是多少吗?
I got the same exception. 我有同样的例外。 I googled and found your question without answer :) 我用Google搜索,发现您的问题没有答案:)
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 Console上的“ mydomain-> Configuration-> JTA”上将“超时秒数”从300更改为1000(可能会增加,具体取决于您的事务超时),或者将应用程序服务器上的JTA超时增加。
Then, for hibernate.cfg.xml you may check this answer: Hibernate/MySQL Connection Timeout 然后,对于hibernate.cfg.xml,您可以检查以下答案: Hibernate / MySQL连接超时
It works. 有用。
