Spring Integration http出站网关POST响应不包含转义的＆符号

Question

The original POST response received contains XML like below having escaped ampersand &

<Order>test&amp;test</Order>

But the Java application is receiving it as below where & is not escaped:

<Order>test&test</Order>

I would prefer to receive the original XML having escaped ampersand & in the XML.

The Spring Integration configuration used to handle POST request response is below:

   <int:chain input-channel="requestChannel">
        <int-http:outbound-gateway url="http://example.com"
                                   http-method="POST"
                                   expected-response-type="java.lang.String"
                                   request-factory="requestFactory"
                                   charset="UTF-8"                                   
    />
    </int:chain>

   <bean id="requestFactory"
         class="org.springframework.http.client.SimpleClientHttpRequestFactory">
        <property name="connectTimeout" value="10000"/>
        <property name="readTimeout"    value="10000"/>
    </bean>

I was wondering if I was missing anything in the above configurations. What can be the reason that & is automatically converted to & in the payload that I extract from POST response.

The other interesting thing that I noticed is when if the server side is sending > symbol Example <Order>test&gt;test</Order> I am receiving it as the same ie <Order>test&gt;test</Order> ; But if the server is sending back both > and & together example <Order>test&gt;test&amp;test</Order> I am receiving it as <Order>test>test&test</Order>

If you look at a network trace, I think you'll find that is happening on the server side.

You might have to send & .
