Question

我想让Spring在heroku平台上使用CloudAMQP。这是我的背景：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main-details">
            <div class="ClassA" style="display:none;">
                <div class="Inner-Details">
ClassA
                </div>
                <div class="Inner-Details">

                </div>
            </div>
            <div class="ClassB" style="display:none;">
                <div class="Inner-Details">
ClassB
                </div>
                <div class="Inner-Details">

                </div>
            </div>
            <div class="ClassC" style="display:none;">
                <div class="Inner-Details">
ClassC
                </div>
                <div class="Inner-Details">

                </div>
            </div>
</div>

但是我遇到了一些奇怪的事情：在本地它完全正常，传递CLOUDAMQP_URL = localhost，但在heroku上我得到以下异常：

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        exchange="myExchange" routing-key="foo.bar"/>

    <rabbit:admin connection-factory="connectionFactory" />

    <rabbit:queue name="myQueue" />

    <rabbit:topic-exchange name="myExchange">
        <rabbit:bindings>
            <rabbit:binding queue="myQueue" pattern="foo.*" />
        </rabbit:bindings>
    </rabbit:topic-exchange>


    <rabbit:listener-container connection-factory="connectionFactory"
        error-handler="exHandler">

        <rabbit:listener ref="foo" method="listen" queue-names="myQueue" />
    </rabbit:listener-container>

    <bean id="foo" class="Foo" />
    <bean id="exHandler" class="BackgroundRejectingErrorHandler" />
</beans>

我将$ {HEROKU_CLOUDAMQP_URL}替换为以下形式的实际连接字符串：

完整堆栈跟踪：

amqp://$user:$password@HOST.cloudamqp.com/VHOST

我做错了吗？

提前致谢。

修正了它。

显然兔子：连接工厂 - ＆gt; HOST＆lt; - 无法处理完整的uri。因此，必须拆分所有参数并一个接一个地传递它们。
