直接上代码，获取 resource 目录下conf文件夹中的所有properties文件

try {ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();Resource[] resources = resolver.getResources("classpath*:config/*.properties");for (Resource r : resources) {log.info("path:{}", r.getFilename());Properties properties = PropertiesLoaderUtils.loadProperties(r);Enumeration<String> names = (Enumeration<String>) properties.propertyNames();while (names.hasMoreElements()) {log.info("name:{}", names.nextElement());}}} catch (Exception e) {e.printStackTrace();}
