Spring多个占位符配置文件解析源码研究
Spring配置文件： <context:property-placeholder location="classpath:/settings.properties" /> <context:property-placeholder location="classpath:/conf.properties"/> settings.properties redis.masterName=mymaster conf.properties home.abroad=1 测试类： @Component public class PropertyPlaceHolderTest { @Value("${redis.masterName}") String masterName; @Value("${home.abroad}") int homeAbroad; public static void main(String[] args) { ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath:applicationContext-test.xml"); PropertyPlaceHolderTest bean = ctx.getBean(PropertyPlaceHolderTest.class);
