用於WebSphere MQ的SSL Java客戶端

Question

我嘗試通過Spring爲WebSphere MQ開發測試客戶端（Java Web應用程序）。

我已經使用NULL_MD5密碼規範爲通道，隊列管理器和連接工廠啓用了SSL安全機制。

這是我的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 
http://www.springframework.org/schema/context/spring-context-2.5.xsd 
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 

    <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> 

問題是，當我嘗試連接到WebSphere MQ異常引發：

奇怪的是，即使我設置SSLCipherSuite屬性，它試圖通過密碼規範得到密碼套件...

有人可以請建議如何解決這個問題嗎？

Answer 1

那麼，經過一番研究後，問題出現在斷言機制中。如果斷言被禁用，一切正常。奇怪的是，即使斷言失敗，你也可以擁有一個完整的工作代碼......而且很遺憾，我找不到設置密碼規範的方法 - 只有密碼套件設置器由MQQueueConnectionFactory類提供。

如果是weblogic服務器，則會在WLS_HOME/user_projects/domains/local-domain-name/bin/setDomainEnv.cmd（.sh）中驗證名爲'debugFlag'的參數。如果您將其設置爲「true」，則應用程序將失敗。或者，您可以在setDomainEnv.cmd（.sh）文件的末尾添加以下JAVA_OPTION：-da：com.ibm.mq ...。通過這種方式，您可以啓用調試。

對於cource來說，解決問題並不是一個可取的方法，但現在它是我能解決這個問題的唯一方法。

Answer 2

這個bug在這裏承認：http://www-01.ibm.com/support/docview.wss?uid=swg1IV36662

並標記爲固定在WebSphere MQ修訂包7.1.0.3。

推薦的（但不是完全令人滿意的）解決方法是使用「-disableassertions」或「-da」禁用JRE命令行中的斷言。
