Context initialization failed （上下文初始化失败 ） @Value(“${xxx}“) Could not resolve placeholder（无法解析占位符）

17:15:56,387 ERROR ContextLoader:316 - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'setmealServiceImpl': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'out_put_path' in value "${out_put_path}"
	at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues

当使用@Value时无法解析占位符，原因是我有两个spring.xml文件第一个文件导入了jdbc.properties,第二个Spring.xml有导入了freemarker.properties ，两个context:property-placeholder

冲突导致得。

解决方法：

删除其中一个context：property-placeholder ，只保留一个context:property-placeholder解决代码如下

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