Question

DynamicurIOutboundEndpoint在Mule 3中没有在运行时获取newUri。我已将我的flow和java代码片段粘贴在下面以供参考。最初我将一个出站端点添加到自定义路由器，然后通过java代码我尝试使用DynamicURIOutboundEndpoint动态更新出站端点的uri。但是在运行时没有使用newUri更新DynamicURIOutboundEndpoint。我也试过扩展AbstractOutboundRouter来代替FilteringOutboundRouter，但结果仍然相同。我已经在网上看到了DynamicURIOutboundEndpoint工作的例子，但它正在使用Mule2。有人可以帮我用mule 3来解决它。我想使用DynamicURIOutboundEndpoint动态设置uri。

<flow name="DemoVipFlow1" doc:name="DemoVipFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP" path="rapp"/>
<logger level="INFO" doc:name="Logger" message="Stage1"/>
<custom-router class="com.vip.DynamicCustomRouter">
<outbound-endpoint address="http://doesnotexist:9999"/>
</custom-router>
</flow>

    try {

        EndpointURI newUri;
        if (ep instanceof OutboundEndpoint) {
            newUri = new MuleEndpointURI(
                    "http://${ipAddress}:8899/jolokia/list", muleContext);
            ep = new DynamicURIOutboundEndpoint((OutboundEndpoint) ep,
                    newUri);
        }
        result = sendRequest(event, message, ep, true);
    } catch (MuleException e) {
        throw new CouldNotRouteOutboundMessageException(event,
                routes.get(0), e);
    }
    return result;
}
}

如果您只想发送到动态网址，那么您的方法就会变得非常复杂。假设ipAddress是可解析的全局属性，则以下工作：

<scripting:component>
    <scripting:script engine="groovy">
        muleContext.client.send('http://${ipAddress}:8899/jolokia/list',
                                eventContext.message)
    </scripting:script>
</scripting:component>

可用于替换custom-router。
