ClassCastException：无法将ActiveMQMapMessage强制转换为ActiveMQMapMessage

时间：2016-12-13 15:25:46

标签： java jms activemq wildfly wildfly-10

我有一个MessageListener从DLQ读取消息，我有消息在经过几次重试后才会处理它们失败。我想在我的应用程序中使用DLQ处理这些消息。

如果我在onMessage（）方法中放置一个断点，IDE会显示onMessage（Message）方法中收到的消息是ActiveMQMapMessage类型，但任何代码都不同意;例如instanceof或cast。

我在Wildfly日志中遇到此错误：

Caused by: java.lang.ClassCastException: org.apache.activemq.command.ActiveMQMapMessage cannot be cast to org.apache.activemq.command.ActiveMQMapMessage

我正在运行外部ActiveMQ代理，并配置了Wildfly。 部署到Wildfly的代码会在队列中放置一条消息。

在Wildfly外部运行的代码读取消息，尝试处理它，但失败了。 ActiveMQ配置设置为多次重试x，然后将该消息放在DLQ上。

正在运行的代理和所有activeMQ代码依赖项是/使用ActiveMQ 5.13.3

有什么想法吗？

更新1：JDK版本

我已经检查了运行的所有内容（Wildfly，ActiveMQ Broker，Queue处理器程序）的JDK版本（1.8.0_111）以及我编译的任何内容： 的pom.xml

<artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <source>1.8</source> <target>1.8</target>

更新2：Wildfly配置

Wildfly正在运行standalone.xml，我已经添加了messaging-activemq扩展名：

<extension module="org.wildfly.extension.messaging-activemq"/>

和子系统（都是从standalone-full.xml复制的）：

        <subsystem xmlns="urn:jboss:domain:messaging-activemq:1.0">
        <server name="default">
            <security-setting name="#">
                <role name="guest" delete-non-durable-queue="true" create-non-durable-queue="true" consume="true" send="true"/>
            </security-setting>
            <address-setting name="#" message-counter-history-day-limit="10" page-size-bytes="2097152" max-size-bytes="10485760" expiry-address="jms.queue.ExpiryQueue" dead-letter-address="jms.queue.DLQ"/>
            <http-connector name="http-connector" endpoint="http-acceptor" socket-binding="http"/>
            <http-connector name="http-connector-throughput" endpoint="http-acceptor-throughput" socket-binding="http">
                <param name="batch-delay" value="50"/>
            </http-connector>
            <in-vm-connector name="in-vm" server-id="0"/>
            <http-acceptor name="http-acceptor" http-listener="default"/>
            <http-acceptor name="http-acceptor-throughput" http-listener="default">
                <param name="batch-delay" value="50"/>
                <param name="direct-deliver" value="false"/>
            </http-acceptor>
            <in-vm-acceptor name="in-vm" server-id="0"/>
            <jms-queue name="ExpiryQueue" entries="java:/jms/queue/ExpiryQueue"/>
            <jms-queue name="DLQ" entries="java:/jms/queue/DLQ"/>
            <connection-factory name="InVmConnectionFactory" entries="java:/ConnectionFactory" connectors="in-vm"/>
            <connection-factory name="RemoteConnectionFactory" entries="java:jboss/exported/jms/RemoteConnectionFactory" connectors="http-connector"/>
            <pooled-connection-factory name="activemq-ra" transaction="xa" entries="java:/JmsXA java:jboss/DefaultJMSConnectionFactory" connectors="in-vm"/>
        </server>
    </subsystem>

我在activemq-rar-5.13.3.rar中修改了ra.xml以禁用嵌入式代理，并将该文件部署到standalone / deployments /

为此，我添加了配置，以便它可以使用外部代理：

<subsystem xmlns="urn:jboss:domain:resource-adapters:4.0">
        <resource-adapters>
            <resource-adapter id="activemq-rar">
                <archive>
                    activemq-rar-5.13.3.rar
                </archive>
                <transaction-support>XATransaction</transaction-support>
                <config-property name="ServerUrl">
                    tcp://localhost:61616
                </config-property>
                <config-property name="UserName">
                    defaultUser
                </config-property>
                <config-property name="Password">
                    defaultPassword
                </config-property>
                <connection-definitions>
                    <connection-definition class-name="org.apache.activemq.ra.ActiveMQManagedConnectionFactory" jndi-name="java:/ActiveMQConnectionFactory" enabled="true" use-java-context="true" pool-name="ActiveMQConnectionFactory"/>
                </connection-definitions>
                <admin-objects>
                    <admin-object class-name="org.apache.activemq.command.ActiveMQQueue" jndi-name="example.queue" use-java-context="true" pool-name="example.queue">
                        <config-property name="PhysicalName">
                            example.queue
                        </config-property>
                    </admin-object>
                </admin-objects>
            </resource-adapter>
        </resource-adapters>
    </subsystem>

我添加了一个<mdb>部分，让它使用已部署的rar：

 <subsystem xmlns="urn:jboss:domain:ejb3:4.0">            
        <mdb>
            <resource-adapter-ref resource-adapter-name="activemq-rar"/>
            <bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>
        </mdb>

您是否在com.mycompany.DLQReader.onMessage（DLQReader.java:67）中将消息转发给ActiveMQMapMessage？您必须有2个到activemq jar的路径。您的应用程序在罐子方面包含哪些内容？你指定了一个jboss-deployment-structure.xml吗？
