Question

我需要配置JMS发送方。但我必须有机会在属性文件中设置DNS名称。我还有应该添加到DNS的参数。我决定创建一个bean，它将完整的url返回给broker。但我有一个启动问题。所以这是我的XML：

<bean id="path" class="com.promptlink.stbtp.Config" factory-method="getJMSPath"/>


<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
    <property name="brokerURL" ref="path"/>
</bean>

这是最后一个链接：

nio://10.20.6.192:9091?connectionTimeout=3000&amp;jms.useAsyncSend=true&amp;wireFormat.tightEncodingEnabled=false

如果我将链接直接设置为属性的值 - 没有问题。 JMS开局不错。但是当我试图将链接作为bean传递时 - 它崩溃了。例外：

那么我做错了什么，以及如何解决这个问题？我只需要 - 它将URL传递给JMS代理。

Answer 1

这与配置上下文有关。在XML中指定值时该 require('Connections.php'); 被正确解码为＆安培; 由XML解析器。所以传递给brokerURL属性的实际值是nio：//10.20.6.192：9091？connectionTimeout = 3000＆amp; jms.useAsyncSend = true＆amp; wireFormat.tightEncodingEnabled = false

这是因为＆amp;是XML中的特殊字符，需要进行转义

使用代码生成URL时，请确保使用正确的格式

&amp;

像bean方法一样配置brokerURL
