Spring和Hibernate突然将事务设置为只读 [英] Spring and Hibernate suddenly set the transaction to readonly

问题描述

我们有一个运行在JBoss 4.2.3上的应用程序，使用Spring 2.5.2和Hibernate 3.2.6.ga.这在Linux JEE01 2.6.16.60-0.54.5-smp上运行，使用自己的用户。在另一台机器上写入Oracle 10G数据库。

我们使用标准视图 - >服务 - > dao分层。每个dao用@Repository进行注释。

这些都是24/7全天候运行，没有太多问题，但是每隔几天，有时候整整一天系统进入一种糟糕的状态，无法再向数据库写入任何内容。这些堆栈跟踪出现在日志中：

  org.springframework.dao.InvalidDataAccessApiUsageException：写入操作不允许读取
 -only模式（FlushMode.NEVER / MANUAL）：
将会话变为FlushMode.COMMIT / AUTO或从事务
定义中移除'readOnly'标记。 
  

我们扫描了整个系统，并且系统中有一个地方将flushmode临时设置为手动之后，一个finally块将其设置回原来的值。这是因为我们不希望在查询运行之前将状态刷新到数据库。所以我们不能很容易地改变这一点。正常的FlushMode被设置为AUTO，并且在几个地方我们暂时将其设置为COMMIT并将其切换回默认。

只有服务器重新启动才能将系统恢复到现在的问题是：为什么系统将所有交易设置为只读/手动刷新模式？我搜索了这个，但找不到解决方案。

这是我们的spring和hibernate配置（只显示部分内容）：

这一切工作正常

解决方案

在您的web.xml中：

 < filter> 
< filter-name> openSessionInViewFilter< / filter-name> 
< filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter< / filter-class> 
< init-param> 
< param-name> flushMode< / param-name> 
<参数值> AUTO< /参数值> 
< / init-param> 
< / filter> 
  

We have an application running on JBoss 4.2.3, using Spring 2.5.2 and Hibernate 3.2.6.ga. This is running on Linux JEE01 2.6.16.60-0.54.5-smp, using its own user. Writing to a Oracle 10G database on another machine.

We're using a standard view -> service -> dao layering. Where each dao is annotated with @Repository.

This is all running 24/7 without many problems, but every several days and sometimes a couple of times in one day the whole system goes into a bad state where nothing can be written to the database anymore. These stacktraces appear in the logs:

org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not
      allowed in read-only mode (FlushMode.NEVER/MANUAL): 
Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction
      definition.

We scanned the complete system, and there is one place in the system where the flushmode is temporarely set to MANUAL after which a finally block set its back to its original value. This is because we do not want to flush the state to the database before this query runs. So we can't change this very easily. The normal FlushMode is set to AUTO and on several places we temporarily set it to COMMIT and switching it back to the default again.

Only a server restart restores the system back to working order.

The question is: why does the system set all transactions to readonly/manual flush mode? I googled this but could not find a solution.

This is our spring and hibernate configuration (only relevants part showing):

     <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
  <property name="dataSource">
   <ref bean="datasourceName" />

 </bean>

  <property name="sessionFactory" ref="sessionFactory" />
 </bean>

 <tx:advice id="txAdvice" transaction-manager="txManager" >
  <!-- the transactional semantics... -->

            <tx:method name="delete*" read-only="false"
    propagation="REQUIRED" rollback-for="java.lang.Exception" />
   <!-- other methods use the default transaction settings (see below) -->
   <tx:method name="*" read-only="true" propagation="REQUIRED" />
  </tx:attributes>
 </tx:advice>

解决方案

in your web.xml put :

<filter>
    <filter-name>openSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    <init-param>
        <param-name>flushMode</param-name>
        <param-value>AUTO</param-value>
    </init-param>
</filter>
