在 wso2 套接字上发送消息，出现异常

Question

我正在尝试在 wso2 框架中通过 TCP 发送消息。我在日志中收到此异常：

[2015-08-20 12:21:50,098] ERROR - TCPWorker Error while processing TCP request through the Axis2 engine

以下是启动 TCP 的 axis2 conf：

<transportReceiver name="local" class="org.wso2.carbon.core.transports.local.CarbonLocalTransportReceiver"/>

<transportReceiver name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportListener">
                <parameter name="transport.tcp.port">6060</parameter>
</transportReceiver>

和wso2.xml:

<definitions xmlns="http://ws.apache.org/ns/synapse">

    <sequence name="fault">
        <makefault>
            <code xmlns:tns="http://www.w3.org/2003/05/soap-envelope" value="tns:Receiver"/>
            <reason value="Mediation failed."/>
        </makefault>
        <send/>
    </sequence>


    <proxy xmlns="http://ws.apache.org/ns/synapse"
           name="TCPProxy"
           transports="https,http"
           statistics="disable"
           trace="disable"
           startOnLoad="true">
        <target>
            <inSequence>
                <log level="full"/>
            </inSequence>
            <outSequence>
                <send/>
            </outSequence>
        </target>
        <parameter name="transport.tcp.port">6060</parameter>
        <parameter name="transport.tcp.contentType">application/xml</parameter>
        <description/>
    </proxy>
</definitions>

Answer 1

在 tcp 端口 6060 上收到消息时，似乎在 ESB 中找不到代理服务。

我不习惯 WSO2 中的 tcp 传输，但我想知道您代理定义中的 "transports" 属性是否应该包含 "tcp" 而不是 "https,http" ：

<proxy xmlns="http://ws.apache.org/ns/synapse"
           name="TCPProxy"
           transports="tcp"
           statistics="disable"
           trace="disable"
           startOnLoad="true">
        <target>
            <inSequence>
                <log level="full"/>
            </inSequence>
            <outSequence>
                <send/>
            </outSequence>
        </target>
        <parameter name="transport.tcp.port">6060</parameter>
        <parameter name="transport.tcp.contentType">application/xml</parameter>
        <description/>
    </proxy>
