不使用PropertyPlaceholderConfigurer加载属性文件

Question

I have a requirement where I have to load a property file which contains CQ5 connection details from my project and provide it as bean properties in a jar which is added in my maven dependency. My Project is using this jar to connect to CQ so I should be able to provide the CQ Connection details to that project as bean properties. Now my project is not spring based so i cannot use PropertyPlaceholderConfigurer whereas the jar added as Maven dependency is Spring based.

Is there any other way to replace value in below bean properties.

<bean id="slingJsonRequestor"       class="com.my.project.content.requestor.SlingRequestor">
    <constructor-arg name="suffix" value="json.js"></constructor-arg>
    <constructor-arg name="resourceBlacklist" ref="slingBlacklistCache"></constructor-arg>
    <property name="url" value="${cq-url}"></property>
    <property name="urlCacId" value="${cq-url-cacid}"></property>
    <property name="urlTemplate" value="${cq-url-template}"></property>
</bean>

Please provide a non spring solution to achieve this.

Answer 1

Yes, it is possible to do it with Maven.

Maven Resources Plugin

You simply add a properties element and a resource element to your pom.xml:

<properties>
    <myproperty>A special value</myproperty>
</properties>

<build>
    <resources>
      <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
        <includes>
            <include>**/myproperties.properties</include>
        </inlcudes>
      </resource>
    </resources>
</build>

Then if the text ${myproperty} is encountered in myproperties.properties maven will replace it with the property value from pom.xml(Not so different from Spring, hey?)
