  <!-- Inbound/Outbound Channels -->
    <int:channel id="serviceSearchRequest" />
    <int:channel id="serviceSearchResponse" />


    <int-http:inbound-gateway id="inboundEmployeeSearchRequestGateway"
        supported-methods="GET, POST" request-channel="serviceSearchRequest"
        reply-channel="serviceSearchResponse"
        mapped-response-headers="Content-Type" 
        path="XXX/service/search" request-payload-type="java.lang.String"
        reply-timeout="5000">
    </int-http:inbound-gateway>

In the above configuration if I want to externalize the value of path i.e If I want to fetch the value from a property file, how to achieve this?

The modified configuration

回答1:


Use normal Spring property placeholders...

<context:property-placeholder location="classpath:com/foo/my.properties"/>

path="${my.path}"

EDIT:

When running in a servlet context, the file has to be located somewhere in the web context, such as...

<context:property-placeholder location="classpath:WEB-INF/resthttpurl.properties"/>

...with your current configuration, the file would have to be located alongside the WEB-INF directory.

If you want the properties file outside of the war file, you need to put it somewhere on the app server's classpath that is visible to the war classloader hierarchy, or use file:/somewhere/on/the/filesystem/resthttpurl.properties.
