Question

我想在同一事务中的数据库表和JMS队列中插入记录。目前我正在使用Transaction scope来实现这一目标。

<transactional action="ALWAYS_BEGIN" doc:name="Transactional">
    <db:insert config-ref="MySQL_Configuration" doc:name="Database">
        <db:parameterized-query><![CDATA[INSERT INTO CUSTOMER(NAME, AGE) VALUES(#[payload.name],#[payload.age])]]></db:parameterized-query>
    </db:insert>
    <jms:outbound-endpoint queue="${queue.name}" connector-ref="Active_MQ" doc:name="JMS">
        <jms:transaction action="ALWAYS_JOIN"/>
    </jms:outbound-endpoint>
</transactional>

但是我得到了以下错误：

org.mule.api.transaction.TransactionException: Endpoint is transactional but transaction does not support it

现在我使用了XA-Transaction

<jms:activemq-xa-connector name="Active_MQ_XA" specification="1.1" brokerURL="${activemq.broker.url}" validateConnections="true" doc:name="Active MQ" />

<db:mysql-config name="MySQL_XA_Configuration" host="${db.host}" port="${db.port}" user="${db.user}" password="${db.password}" database="${db.name}" useXaTransactions="true" doc:name="MySQL Configuration" />

<jbossts:transaction-manager doc:name="JBoss Transaction Manager" />

<ee:xa-transactional action="ALWAYS_BEGIN" doc:name="Transactional">
    <db:insert config-ref="MySQL_XA_Configuration" doc:name="Database">
        <db:parameterized-query><![CDATA[INSERT INTO CUSTOMER(NAME, AGE) VALUES(#[payload.name],#[payload.age])]]></db:parameterized-query>
    </db:insert>
    <jms:outbound-endpoint queue="${queue.name}" connector-ref="Active_MQ_XA" doc:name="JMS">
        <xa-transaction action="ALWAYS_JOIN"/>
    </jms:outbound-endpoint>
</ee:xa-transactional>

这次我又得到了一个例外

有人可以解决这个问题吗？

似乎useXaTransactions="true"无法处理mysql数据库连接器。我已配置显式mySqlXADataSource。它对我有用。

<jbossts:transaction-manager doc:name="JBoss Transaction Manager" />

<spring:beans>
    <spring:bean id="mySqlXADataSource" name="MySqlXADataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource">
        <spring:property name="user" value="${db.user}" />
        <spring:property name="password" value="${db.password}" />
        <spring:property name="url" value="${mysql.driver.url}" />
    </spring:bean>
</spring:beans>

<db:mysql-config name="MySQL_XA_Configuration" dataSource-ref="mySqlXADataSource" doc:name="MySQL Configuration" />

<jms:activemq-xa-connector name="Active_MQ_XA" specification="1.1" brokerURL="${activemq.broker.url}" validateConnections="true" doc:name="Active MQ" />

<ee:xa-transactional action="ALWAYS_BEGIN" doc:name="Transactional">
    <db:insert config-ref="MySQL_XA_Configuration" doc:name="Database">
        <db:parameterized-query><![CDATA[INSERT INTO CUSTOMER (NAME,AGE)VALUES(#[payload.customer.name],#[payload.customer.age])]]></db:parameterized-query>
    </db:insert>
    <jms:outbound-endpoint queue="${queue.name}" connector-ref="Active_MQ_XA" doc:name="JMS">
        <xa-transaction action="ALWAYS_JOIN"/>
    </jms:outbound-endpoint>
</ee:xa-transactional>
