apache-camel - 为什么以下捆绑包处于宽限期？

问题描述

我有两个包含camel-activemq 东西的蓝图文件包。喜欢

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
	..
    <cm:property-placeholder id="jms.placeholder" persistent-id="com.mycompany.context">
        <cm:default-properties>
            <cm:property name="activemq.url" value="${activemq.url}" />
            <cm:property name="activemq.user" value="${activemq.user}" />
            <cm:property name="activemq.password" value="${activemq.password}" />
        </cm:default-properties>
    </cm:property-placeholder>
	
	..
    <camelContext xmlns="http://camel.apache.org/schema/blueprint"
                  id="quartzCamelPublisher"
                  autoStartup="true">
        
        <route id="failedMessagePublisher">
            <from uri="vm:failedEventQueue" />
            <to pattern="InOnly" uri="activemq:queue:not-success"/>
        </route>
    </camelContext>
    
    
    <reference id="txMgr" interface="javax.transaction.TransactionManager" />

    <bean id="xaConnectionFactory" class="org.apache.activemq.ActiveMQXAConnectionFactory">
        <property name="brokerURL" value="${activemq.url}" />
        <property name="userName" value="${activemq.user}" />
        <property name="password" value="${activemq.password}" />
        <property name="watchTopicAdvisories" value="false" />
    </bean>

    <bean id="jcaConnectionFactory" class="org.apache.activemq.jms.pool.JcaPooledConnectionFactory"
          init-method="start" destroy-method="stop">
        <property name="transactionManager" ref="txMgr"/>
        <property name="maxConnections" value="10" />
        <property name="name" value="amq" />
        <property name="connectionFactory" ref="xaConnectionFactory"/>
    </bean>

    <bean id="jmsTxConf" class="org.apache.activemq.camel.component.ActiveMQConfiguration">
        <property name="connectionFactory" ref="jcaConnectionFactory" />
        <property name="requestTimeout" value="10000" />
        <property name="transactionTimeout" value="30" />
        <property name="transacted" value="true" />
        <property name="cacheLevelName" value="CACHE_NONE" />
    </bean>

    <bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent" >
        <property name="configuration" ref="jmsTxConf" />
    </bean>
</blueprint>

如果我在第二个捆绑蓝图文件中使用常量值，则一切正常。一旦我在那里使用 ${activemq.url} 之类的配置，它看起来找不到它并尝试无限次数地获取它。第二个捆绑包无法解决。

如果我使用第二个配置文件，它只是像 com.mycompany.context_1 这样的重复配置文件，那么第一个包无法通过以下事务相关消息解析。以下捆绑包处于优雅状态的原因是什么？

解决方案

从蓝图文件中删除所有默认条目已解决此问题。并且使用 cofig 文件中的属性也可以正常工作。

<?xml version="1.0" encoding="UTF-8"?>
<blueprint ...
    <cm:property-placeholder id="jms.placeholder" persistent-id="com.mycompany.context">
        <cm:default-properties>
        </cm:default-properties>
    </cm:property-placeholder>

	....
    <bean id="xaConnectionFactory" class="org.apache.activemq.ActiveMQXAConnectionFactory">
        <property name="brokerURL" value="${activemq.url}" />
        <property name="userName" value="${activemq.user}" />
        <property name="password" value="${activemq.password}" />
        <property name="watchTopicAdvisories" value="false" />
    </bean>

</blueprint>
