未设置ActiveMQ RedeliveryPolicy

时间:2018-10-23 16:44:10

标签: java spring-boot groovy apache-camel activemq

我正在使用:

  • SpringBoot 2.0.4
  • ActiveMQ 5.15.5
  • Apache Camel 2.22.0
  • Java 1.8
  • 时髦
  • 行家

基本上,我有一个带有Apache Camel路由的SpringBoot应用程序,该路由使用ActiveMQ的消息进行事务处理。我需要在ActiveMQ上设置RedeliveryPolicy,以便在处理中发生错误时,重试该消息多次。

我使用ActiveMQ的bean创建了一个配置类,事务按预期工作,但是RedeliveryPolicy不起作用。有人可以帮我了解这是怎么回事吗?

以下是产生错误的消息的日志输出:

这是我的ActiveMQ配置类:

        activeMQConnectionFactory.setRedeliveryPolicy(redeliveryPolicy)

        JmsTransactionManager txManager = new JmsTransactionManager()
        txManager.connectionFactory = activeMQConnectionFactory
        txManager.rollbackOnCommitFailure = true

        txManager
    }

}

不久前,我遇到了dlq队列的问题-并非代码中设置的所有参数都能正常工作。我必须将设置添加到acitvemq配置。是的,划分配置不是一个好的决定,但我没有找到其他配置。 以下是我的jms配置类和通过activemq.xml进行示例队列配置:

@Configuration
@EnableJms
public class JmsConfig {

    private Environment env;

    @Autowired
    public void setEnv(Environment env) {
        this.env = env;
    }

    @Bean(name = "activemq")
    public ActiveMQComponent activemq(@Qualifier("activemqTransactionManager") JmsTransactionManager jmsTransactionManager,
                                      @Qualifier("activemqConnectionFactory") ConnectionFactory connectionFactory) {
        ActiveMQComponent activeMQComponent = new ActiveMQComponent();
        activeMQComponent.setTransactionManager(jmsTransactionManager);
        activeMQComponent.setConnectionFactory(connectionFactory);
        return activeMQComponent;
    }

    @Bean(name = "activemqJmsTemplate")
    public JmsTemplate jmsTemplate(@Qualifier("activemqConnectionFactory") ConnectionFactory connectionFactory) {
        JmsTemplate template = new JmsTemplate();
        template.setConnectionFactory(connectionFactory);
        return template;
    }

    @Bean(name = "activemqTransactionPolicy")
    public SpringTransactionPolicy activemqTransactionPolicy(
            @Qualifier("activemqTransactionManager") JmsTransactionManager jmsTransactionManager) {
        SpringTransactionPolicy springTransactionPolicy = new SpringTransactionPolicy(jmsTransactionManager);
        springTransactionPolicy.setPropagationBehaviorName("PROPAGATION_REQUIRED");
        return springTransactionPolicy;
    }

    @Bean(name = "activemqTransactionManager")
    public JmsTransactionManager activemqTransactionManager(
            @Qualifier("activemqConnectionFactory") ConnectionFactory connectionFactory) {
        return new JmsTransactionManager(connectionFactory);
    }

    @Bean(name = "activemqConnectionFactory")
    public ConnectionFactory connectionFactory(@Qualifier("activemqRedeliveryPolicy") RedeliveryPolicy redeliveryPolicy) {
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL("tcp://" + env.getProperty("queue.url"));
        connectionFactory.setTrustAllPackages(true);

        RedeliveryPolicyMap map = connectionFactory.getRedeliveryPolicyMap();
        map.put(new ActiveMQQueue("queueName.DLQ"), redeliveryPolicy);
        return connectionFactory;
    }

    @Bean(name = "activemqRedeliveryPolicy")
    public RedeliveryPolicy redeliveryPolicy() {
        RedeliveryPolicy redeliveryPolicy = new RedeliveryPolicy();
        redeliveryPolicy.setMaximumRedeliveries(0);
        return redeliveryPolicy;
    }
}

activevq.xml中的更改:

<destinationPolicy>
    <policyMap>
        <policyEntries>
            <!--set dead letter queue for our queue. It name will be "myQueueName.DLQ"-->
            <policyEntry queue="myQueueName">
                <deadLetterStrategy>
                    <individualDeadLetterStrategy queuePrefix="" queueSuffix=".DLQ"/>
                </deadLetterStrategy>
            </policyEntry>
            <policyEntry topic=">">
                <pendingMessageLimitStrategy>
                    <constantPendingMessageLimitStrategy limit="1000"/>
                </pendingMessageLimitStrategy>
            </policyEntry>
        </policyEntries>
    </policyMap>
</destinationPolicy>

<plugins>
<redeliveryPlugin fallbackToDeadLetter="true" sendToDlqIfMaxRetriesExceeded="true">
    <redeliveryPolicyMap>
        <redeliveryPolicyMap>
            <redeliveryPolicyEntries>
                <!--Set the redelivery delay to one hour-->
                <redeliveryPolicy queue="myQueueName.DLQ" maximumRedeliveries="-1" redeliveryDelay="3600000"/>
            </redeliveryPolicyEntries>
        </redeliveryPolicyMap>
    </redeliveryPolicyMap>
</redeliveryPlugin>
</plugins>

这里有两个问题

1。您有两个交易经理

由于在配置骆驼ActiveMQ组件的以下两行中,您配置了两个事务管理器。这是问题的根源。

activeMQComponent.transacted = true // activates local JMS transactions
activeMQComponent.transactionManager = txManager() // additional tx manager

如果您只想使用ActiveMQ的事务性,则您不需要配置Spring事务管理器

配置的这两行足以与ActiveMQ代理进行本地事务。

activeMQComponent.transacted = true
activeMQComponent.lazyCreateTransactionManager = false

因此,您应该删除此行以及整个txManager bean

activeMQComponent.transactionManager = txManager()

如果您当前在骆驼路线中设置了交易标记,则也必须将其删除。正如我所写,即使删除了所有这些,从ActiveMQ消耗的路由仍会被处理。

2。重新交付不起作用

您尚未发布您的Camel路线,但是根据错误输出,我认为经纪人不会重新投放,因为错误是由Camel处理的

当发生错误时,将启动Camel错误处理程序o.a.camel.processor.DefaultErrorHandler,并且由于它处理错误,因此消息是针对代理提交的,因此不会重新交付。

尝试禁用Camel错误处理,以查看代理是否根据错误重新发送消息。

errorHandler(noErrorHandler());
