解決com.atomikos.icatch.RollbackException: Prepare: NO vote

使用atomikos时，事务默认超时时间是100000毫秒，超过这个时间，提交事务就会抛出异常com.atomikos.icatch.RollbackException: Prepare: NO vote。

今天总算通过bing找到了答案，记录一下。

在网上很多说的要设置com.atomikos.icatch.max_timeout和com.atomikos.icatch.default_jta_timeout，居然都没说怎么设置，集成Spring的情况下，第一时间想到在bean的属性里配置，结果没找到（default_jta_timeout可以在org.springframework.transaction.jta.JtaTransactionManager中找到defaultTimeOut属性与之匹配，但是max_timeout没有找到，官方文档(https://www.atomikos.com/Documentation/JtaProperties)也没说，只是说设置max_timeout和UserTransaction.setTransactionTimeout()是一个意思，结果我配置了半天，没有效果）。最后搞明白了，需要在classpath下建一个jta.properties（或者transactions.properties）文件（事务管理器的配置），来配置事务相关属性，如下是我的jta.properties。

default_jta_timeout与com.atomikos.icatch.max_timeout的区别：default_jta_timeout表示开启事务时，默认的超时时间，max_timeout表示最大的超时时间，0表示无限时间。如果default_jta_timeout设置的值超过了max_timeout，会自动将超时时间截断，使用max_timeout的值（日志会打印出来）。

如果是spring不是用的springBoot:

Spring的配置文件

<!-- Atomikos 事务管理器配置 -->
<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"init-method="init" destroy-method="close">
<!-- <property name="startupTransactionService" value="false" /> -->
<!-- close()时是否强制终止事务 -->      
<property name="forceShutdown" value="false" /></bean>
        <!-- Atomikos UserTransaction配置 -->
<bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp"></bean>
<!-- JTA事务管理器 -->
<bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager"><ref bean="atomikosTransactionManager" />
</property><property name="userTransaction"><ref bean="atomikosUserTransaction" /></property>
