Java 如何在spring context.xml中使用pom属性？

我有pom文件（pom.xml）：

我想在我的spring context.xml（appContext.xml）中使用这个属性：

我相信您可以使用和配置它。Spring将独立地从属性文件中读取

      ...
  <properties>
      <certificate-manager.default-client-certDN>Default Client</certificate-manager.default-client-certDN>
      <certificate-manager.path-to-store>D:\Projects\PPP\apache-tomcat-7.0.29\</certificate-manager.path-to-store>
      <certificate-manager.store-password>12345</certificate-manager.store-password>
      <certificate-manager.alias>root</certificate-manager.alias>
  </properties>

certificateManager.defaultClientCertDN=${certificate-manager.default-client-certDN}
certificateManager.pathToStore=${certificate-manager.path-to-store}
certificateManager.storePassword=${certificate-manager.store-password}
certificateManager.alias=${certificate-manager.alias}

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

    <bean id="certificateManager" class="com.exadel.mdp.security.certificate.CertificateManagerImpl">
        <constructor-arg name="defaultClientCertDN" value="${certificateManager.defaultClientCertDN}"/>
        <constructor-arg name="pathToStore" value="${certificateManager.pathToStore}"/>
        <constructor-arg name="storePassword" value="${certificateManager.storePassword}"/>
        <constructor-arg name="alias" value="${certificateManager.alias}"/>
    </bean>
