问题描述

  <!-- 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>

在上面的配置中，如果我想外部化路径的值，即如果我想从属性文件中获取值，如何实现?

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?

推荐答案

使用普通的 Spring 属性占位符...

Use normal Spring property placeholders...

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

path="${my.path}"

编辑:

在 servlet 上下文中运行时，文件必须位于 Web 上下文中的某个位置，例如...

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"/>

...根据您当前的配置，该文件必须位于 WEB-INF 目录旁边.

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

如果你想要war文件之外的属性文件，你需要把它放在应用服务器的类路径上对war类加载器层次结构可见的某个地方，或者使用file:/somewhere/on/the/filesystem/resthttpurl.properties.

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.
