求助Springframework 4.3.2 加载配置文件的问题

springframework 的版本是 4.3.2 采用以下代码加载配置文件

<context:property-placeholder
		ignore-resource-not-found="true" local-override="true"
		location="classpath:/META-INF/configuration/environments/application-backend-dev.properties" />
​

maven 结构，配置文件路径 src/main/resources/META-INF/configuration/environments/application-backend-dev.propertie

spring 配置文件头如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="
          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
          http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
          http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
​

加载不到配置文件中的属性 ${} 取不到值。谁来解决一下，注意 springframework 的版本
