将属性从inSequence传递到outSequence [英] Pass property from inSequence to outSequence

问题描述

我正在将带有代理的消息发送到HL7 TCP/IP端口，并在outSequence中获得响应.但是我的问题是inSequence中设置的所有属性都不再可用.它们都是空的.我测试了所有不同的范围(传输，axis2，axis2-client)，但没有一个起作用.

I'm sending a message with a Proxy to a HL7 TCP/IP port and get the response in the outSequence. But my problem is that all properties set in the inSequence are not anymore available. All of them are null. I tested with all the different scopes (transport, axis2, axis2-client), but none of them worked.

我在这篇文章中看到应该可行. HL7发送方是否正在破坏属性? 如何从outSequence中的inSequence中使用我的属性?

I saw in this post that it should be possible. Is the HL7 sender destroying the properties? How can use my properties from the inSequence in the outSequence?

我的代理示例(从ActiveMQ JMS获取消息并将其发送到HL7端口4000):

Example of my Proxy (get message from ActiveMQ JMS and sends to HL7 port 4000):

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" xmlns:hl7="http://wso2.org/hl7"  xmlns:urn="urn:hl7-org:v2xml" name="demo_toHL7" transports="jms" startOnLoad="true" trace="disable">
    <parameter name="transport.jms.Destination">demo_qFilter</parameter>
    <parameter name="transport.jms.ConnectionFactory">queueBlocking</parameter>
    <parameter name="transport.jms.DestinationType">queue</parameter>
    <parameter name="transport.jms.ContentType">
        <rules>
            <jmsProperty>contentType</jmsProperty>
            <default>application/edi-hl7</default>
        </rules>
    </parameter>
    <target faultSequence="rollbackSequence">
        <inSequence>
            <log level="full"/>
            <property name="ClientApiNonBlocking" scope="axis2" action="remove"/>
            <property name="testProperty" value="blabla" scope="transport"/>
            <property name="messageType" value="application/edi-hl7" scope="axis2"/>
            <property name="ContentType" value="application/edi-hl7" scope="axis2"/>            
            <send>
                <endpoint>
                    <address uri="hl7://localhost:4000"/>
                </endpoint>
            </send>
        </inSequence>
        <outSequence>
            <log level="custom">
                <property name="PROPERTY" expression="get-property('transport','testProperty')"/>
            </log>
        </outSequence>
    </target>
</proxy>

我正在使用WSO2 ESB 4.0.3并安装了HL7功能.作为接收者，我使用7edit应用程序.

I'm using WSO2 ESB 4.0.3 and installed the HL7 Feature. As receiver I use the 7edit application.

推荐答案

尝试将属性范围设置为默认/突触"

Try with property scope as "default/synapse"

尝试将属性范围设置为默认":

Try with property scope as "default":

将传输属性从inSequence发送到outSequence(代表默认范围):

Sending a transport property from the inSequence to the outSequence (on behalf of the default scope):

<inSequence>
   ...
   <property name="myPropertyInTransport" value="myValue" scope="transport"/>
   <property name="myPropertyInDefault" expression="get-property('transport','myPropertyInTransport')" scope="default"/>
   ...
</inSequence>
<outSequence>
   ...
   <property name="myPropertyInTransport" expression="get-property('default', 'myPropertyInDefault')" scope="transport"/>
   <!-- Now myProperty is also available in the outSequence -->
   ...
</outSequence>
