Question

在Apache Camel上开发了一个小组件，作为多播器，将传入的消息转发到一组端点。

此组件在WebLogic服务器上运行。

版本详情：

JDK：1.6 / 1.7.0_75
Apache Camel：2.14.1
WebLogic：10.3.6

出现了一项新的要求，即在运行时修改目标端点集，而无需重建和重新部署组件。

第一个想法是使用Apache Camel提供的JMX功能来实现这一目标。

JConsole用作JMX客户端。

jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;%JAVA_HOME%\lib\tools.jar;%WL_HOME%\server\lib\wlfullclient.jar;%WL_HOME%\server\lib\wljmxclient.jar -debug

作为我们使用的连接字符串：

service:jmx:rmi:///jndi/iiop://localhost:7001/weblogic.management.mbeanservers.runtime

管理对象路由（see available docu）中的方法 updateRouteFromXML 似乎是此工作的正确方法。

为了测试此方法，首先调用 dumpRouteAsXml 以获取要以XML格式修改的路由的描述。

路线样本如下所示：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<route customId="false" id="route7" xmlns="http://camel.apache.org/schema/spring">
<from uri="servlet:///TESTServer"/>
<convertBodyTo type="[B" id="convertBodyTo7"/>
<removeHeader headerName="CamelHttpPath" id="removeHeader7"/>
  <multicast parallelProcessing="true" timeout="3000" id="multicast7">
    <to uri="http://ip1:8007/IOCServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to19"/>
    <to uri="http://ip2:8007/IOCServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to20"/>
    <to uri="http://ip3:8007/IOCServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to21"/>
  </multicast>
</route>

此xml用作 updateRouteFromXML 的输入：

<route customId="false" id="route7" xmlns="http://camel.apache.org/schema/spring">
<from uri="servlet:///TESTServer"/>
<convertBodyTo type="[B" id="convertBodyTo7"/>
<removeHeader headerName="CamelHttpPath" id="removeHeader7"/>
  <multicast parallelProcessing="true" timeout="3000" id="multicast7">
    <to uri="http://ip1:8007/IOCServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to19"/>
    <to uri="http://ip2:8007/IOCServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to20"/>
    <to uri="http://ip3:8007/IOCServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to21"/>
  </multicast>
</route>

我们尝试了几种变体（例如没有xml标题）。

但总是得到同样的例外：

是否有人通过JMX成功调用 UpdateRouteFromXml ？

使用jdk1.7.0_75进行相同的错误测试

当WebLogic服务器在我的笔记本电脑上本地运行时，我尝试从JConsole进行本地连接（而不是远程连接），然后重新测试。通过这样做我摆脱了CORBA错误，并且可以看到Camel抛出异常，但无法在客户端加载。

引起：java.lang.ClassNotFoundException：org.apache.camel.FailedToCreateRouteException（没有安全管理器：禁用RMI类加载器）

我向jConsole类路径添加了camel-core.jar：

jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;%JAVA_HOME%\lib\tools.jar;%WL_HOME%\server\lib\wlfullclient.jar;%WL_HOME%\server\lib\wljmxclient.jar;%M2_HOME%\repository\org\apache\camel\camel-core\2.14.1\camel-core-2.14.1.jar -debug

再次重新测试：

用于测试的输入XML（实际上它是从 dumpRouteAsXml 输出的）

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<route customId="false" id="route1" xmlns="http://camel.apache.org/schema/spring">
    <from uri="servlet:///TESTServer"/>
    <convertBodyTo type="[B" id="convertBodyTo1"/>
    <removeHeader headerName="CamelHttpPath" id="removeHeader1"/>
    <multicast parallelProcessing="true" timeout="3000" id="multicast1">
        <to uri="http://ip-address1:6001/TARGETServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to1"/>
        <to uri="http://ip-address2:6001/TARGETServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to2"/>
        <to uri="http://ip-address3:6001/TARGETServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to3"/>
    </multicast>
</route>

现在记录了Camel抛出的异常，我可以看到Route定义中存在错误。我不能简单地复制 dumpRouteAsXml 的输出并将其粘贴到 updateRouteFromXml

引起：java.lang.ClassNotFoundException：[B

完成堆栈跟踪：

这个“[B”代表byte [] .class。您可以在下面看到以编程方式设置的实际配置。

from("servlet:///TESTServer")
    .convertBodyTo(byte[].class)
    .removeHeader(Exchange.HTTP_PATH)
    .multicast()
    .parallelProcessing()
    .timeout(3000)
    .to(eb.getEndpoints("DESTINATIONS1"))
.end();

一些试验和错误，我得到了正确的XML定义并成功调用了 updateRouteFromXml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<route customId="false" id="route3" xmlns="http://camel.apache.org/schema/spring">
    <from uri="servlet:///TESTServer"/>
    <convertBodyTo type="byte[]" id="convertBodyTo3"/>
    <removeHeader headerName="CamelHttpPath" id="removeHeader3"/>
    <multicast parallelProcessing="true" timeout="3000" id="multicast3">
        <to uri="http://ip-address1:9993/TARGETServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to7"/>
        <to uri="http://ip-address2:9993/TARGETServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to8"/>
        <to uri="http://ip-address3:9993/TARGETServer?bridgeEndpoint=true&amp;throwExceptionOnError=false" id="to9"/>
    </multicast>
</route>

谢谢和问候

Apache Camel 2.14以后版本不支持Java 6。您需要使用Java 7或8。

请参阅发行说明的底部：
