Java ClassNotFoundException:com.ibm.mq.jms.MQConnectionFactory（Websphere mq 7.5+；spring jms+；maven tomcat 7插件）

我试图创建一个简单的Webapp来演示如何在Servlet容器（tomcat）中使用WMQ 7.5。我的网络地图基于独立的WMQ示例应用程序。 我的独立应用程序运行良好。

测试用例也很好。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class)
public class MQMessageTest {

    /**
     * Message count fot test
     */
    private static final int MESSAGE_COUNT = 25;

    /**
     * Setting Environment for getting properties
     */
    @Autowired
    private Environment environment;

    /**
     * MQMessageSender for sending messages
     */
    @Autowired
    private MQMessageSender mqMessageSender;

    /**
     * JmsTemplate of Spring JMS
     */
    @Autowired
    private JmsTemplate jmsTemplate;

    @Test
    public void testEqualsOfSentAndReceivedMessages() {

        /*Sending messages to Queue*/
        for (int i = 0; i < MESSAGE_COUNT; i++) {
            mqMessageSender.send("Message with" + System.nanoTime());
        }

        /*Container for received messages*/
        Set<TextMessage> messages = new HashSet<TextMessage>();

        /*Receiving messages from report Queue*/
        for (int i = 0; i < MESSAGE_COUNT; i++) {
            TextMessage message = (TextMessage) jmsTemplate.receive(environment.getRequiredProperty("wmq.queue.test.input.2"));
            messages.add(message);
        }

        assertEquals(messages.size(), MESSAGE_COUNT);
    }
}

请告诉我有什么问题。我如何解决它？何时需要修复：在tomcat、websphere MQ或spring jms中？我试图与jetty合作，但失败了。

WEB初始值设定项

        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(AppConfig.class);

        ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
        servlet.setLoadOnStartup(1);
        servlet.addMapping("/");
    }
}

非常感谢。对不起，我的英语不好。

最后的战争包括MQ jar文件吗？我认为这是一个IBMMQJAR文件丢失的构建问题，因此ClassNotFoundException

我建议使用maven的文件系统存储库，而不是使用systempath直接链接到源代码。参考将MQ JAR添加到此存储库，并将其作为依赖项添加到POM中

---

另一个选项是在catalina.properties中使用共享类加载器。在这里，您可以直接从/opt/mqm/java/lib加载mqjar。

我使用gradle而不是maven解决了这个问题。这个项目现在很小。我认为格拉德尔有更好的机会。谢谢你的回答。你平静的劝告是好的。很遗憾，我不能投票赞成你的答案。我没有理由这样做。

public class WebInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(AppConfig.class);
        ctx.setServletContext(servletContext);

        ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
        servlet.setLoadOnStartup(1);
        servlet.addMapping("/");
    }
}
