我尝试通过 Spring 为 WebSphere MQ 开发一个测试客户端（Java Web 应用程序）。

我使用 NULL_MD5 密码规范为通道、队列管理器和连接工厂启用了 SSL 安全机制。

这是我的 Spring 配置文件：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/context

    <context:annotation-config/>

    <context:property-placeholder location="classpath:jms.properties"/>

    <bean id="jmsFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
        <property name="hostName" value="${queue_hostname}"/>
        <property name="queueManager" value="${queue_manager}"/>
        <property name="channel" value="${queue_channel}"/>
        <property name="port" value="${queue_port}"/>
        <property name="transportType" value="1"/>
        <property name="SSLCipherSuite" value="SSL_RSA_WITH_NULL_MD5"/>
    </bean>

    <bean id="sendDestination" class="com.ibm.mq.jms.MQQueue">
        <property name="baseQueueName">
            <value>queue.inbound</value>
        </property>
    </bean>

    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory">
            <bean class="org.springframework.jms.connection.SingleConnectionFactory">
                <property name="targetConnectionFactory">
                    <ref local="jmsFactory" />
                </property>
            </bean>
        </property>
        <property name="defaultDestination">
            <ref bean="sendDestination" />
        </property>
    </bean>


    <bean id="messageListener" class="com.test.MessageListener" />

    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory">
            <bean class="org.springframework.jms.connection.SingleConnectionFactory">
                <property name="targetConnectionFactory">
                    <ref local="jmsFactory" />
                </property>
            </bean>
        </property>
        <property name="destination" ref="sendDestination" />
        <property name="messageListener" ref="messageListener" />
    </bean>

</beans>

问题是当我尝试连接到 WebSphere MQ 时会引发异常：

奇怪的是，即使我设置了 SSLCipherSuite 属性，它也会尝试通过密码规范获取密码套件......

有人可以建议如何解决这个问题吗？

此错误在此处得到确认：http ://www-01.ibm.com/support/docview.wss?uid=swg1IV36662

并在 Websphere MQ 修订包 7.1.0.3 中标记为已修复。

推荐的（但不是完全令人满意的）解决方法是在 JRE 命令行中禁用断言，使用“-disableassertions”或“-da”。

好吧，经过一些研究，问题似乎出在断言机制上。如果断言被禁用，一切正常。奇怪的是，即使断言失败，您也可以拥有完整的工作代码......而且很遗憾我找不到设置密码规范的方法 - 只有MQQueueConnectionFactory类提供密码套件设置器。

对于 weblogic 服务器，有一个名为“debugFlag”的参数在 WLS_HOME/user_projects/domains/local-domain-name/bin/setDomainEnv.cmd (.sh) 中验证。如果您将其设置为“true”，则应用程序将失败。或者，您可以在 setDomainEnv.cmd (.sh) 文件的末尾添加以下 JAVA_OPTION：-da:com.ibm.mq...。这样您就可以启用调试。

当然，这不是解决问题的首选方法，但目前这是我可以解决的唯一方法。
