XML配置

<?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"
   xsi:schemaLocation="
      http://www.springframework.org/schema/beans 
      http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
      http://www.springframework.org/schema/context 
      http://www.springframework.org/schema/context/spring-context-4.2.xsd">

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

</beans> 

Java配置

@Configuration
@PropertySource("classpath:foo.properties")
public class PropertiesWithJavaConfig {
    //...
}
