@RetryTransaction：如何在发现死锁时使其工作

Concurent Transaction make my Sql statements fail. I'm trying to use [this] dellroad-stuff1. But it seems to be ignored. I m working with spring 3 and hibernate 4.

Concurent Transaction使我的Sql语句失败。我正在尝试使用[this] dellroad-stuff1。但它似乎被忽略了。我正在使用spring 3和hibernate 4。

The error :

错误 ：

15:32:11,331 WARN SqlExceptionHelper:145 - SQL Error: 1213, SQLState: 40001
15:32:11,331 ERROR SqlExceptionHelper:147 - Deadlock found when trying to get lock; try restarting transaction
15:32:11,334 INFO AbstractBatchImpl:195 - HHH000010: On release of batch it still contained JDBC statements

The annoted Function to retry transaction if failed :

如果失败，则重写事务的annoted函数：

@Override   
@RetryTransaction   
@Transactional  
public void save(AnalyseResult analyseResult) {
    final int attempt = RetryTransactionAspect.aspectOf().getAttemptNumber();
    System.out.println("#############");
    System.out.println("Retry Transact : "+attempt);
    System.out.println("#############"); 
    analyseResultDao.save(analyseResult);
}

The Beans.xml

Beans.xml

<!--  An @AspectJ aspect will be interpreted as an aspect by Spring AOP and beans
      in the context will be advised accordingly -->
<aop:aspectj-autoproxy proxy-target-class="true" />

<bean id="hibernateExceptionTranslator" class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/> 

<bean class="org.dellroad.stuff.spring.RetryTransactionAspect" factory-method="aspectOf">

Check you've satisfied all of the following (per the Javadoc):

检查您是否满足以下所有条件（根据Javadoc）：

• The method (and/or the containing type) must be annotated with both @Transactional and @RetryTransaction
• 必须使用@Transactional和@RetryTransaction注释方法（和/或包含类型）
• The @Transactional annotation must have propagation set to either PROPAGATION_REQUIRED or PROPAGATION_REQUIRES_NEW (other propagation values do not involve creating new transactions).
• @Transactional注释必须将传播设置为PROPAGATION_REQUIRED或PROPAGATION_REQUIRES_NEW（其他传播值不涉及创建新事务）。
• In the case of PROPAGATION_REQUIRED propagation, there must not be a transaction already open in the calling thread (under the same transaction manager). In other words, the invoked method must be the one responsible for creating a new transaction.
• 在PROPAGATION_REQUIRED传播的情况下，调用线程（在同一事务管理器下）不得打开事务。换句话说，调用的方法必须是负责创建新事务的方法。
• The method's class must be woven (either at build time or runtime) using the AspectJ compiler with the RetryTransactionAspect aspect (included in the dellroad-stuff JAR file).
• 必须使用带有RetryTransactionAspect方面的AspectJ编译器（包含在dellroad-stuff JAR文件中）编译方法的类（在构建时或运行时）。

• The RetryTransactionAspect aspect must be configured with a PersistenceExceptionTranslator appropriate for the ORM layer being used. The simplest way to do this is to include the aspect in your Spring application context, for example:

  必须使用适合所使用的ORM层的PersistenceExceptionTranslator配置RetryTransactionAspect方面。最简单的方法是在Spring应用程序上下文中包含该方面，例如：

  <bean class="org.dellroad.stuff.spring.RetryTransactionAspect" factory-method="aspectOf" p:persistenceExceptionTranslator-ref="myJpaDialect"/>

  This also gives you the opportunity to change the default values for maxRetries(), initialDelay(), and maximumDelay(), which are applied when not explicitly overridden in the annotation, for example:

  这也使您有机会更改maxRetries（），initialDelay（）和maximumDelay（）的默认值，这些默认值在未在注释中显式覆盖时应用，例如：

  <bean class="org.dellroad.stuff.spring.RetryTransactionAspect" factory-method="aspectOf" p:persistenceExceptionTranslator-ref="myJpaDialect" p:maxRetriesDefault="2" p:initialDelayDefault="25" p:maximumDelayDefault="5000"/>
