Область транзакции Mule и транзакция XA

Question

Я хочу вставить запись в таблицу базы данных и в очередь JMS в той же транзакции. В настоящее время я использую область транзакций для достижения этой цели.

<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> 

Но я получил ниже ошибки:

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

Теперь я использовал 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> 

на этот раз я получил еще одно исключение

Может кто-нибудь, пожалуйста, решить проблема?

Answer 1

Кажется useXaTransactions="true" не работает на разъеме mysql db. Я настроил явно mySqlXADataSource. Это сработало для меня.

<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>
