本文主要是介绍javaE中获取项目properties文件中的常量数据,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
xiangmu\ app\ src\ main\ resources
fileUpload.resources文件
upload.userId = -1 upload.srcSystem = 131452021 upload.token = vfZQIDAQAB upload.businessId = 111
public class UploadUtil { private static Map<String, Object> uploadParamsMap = new HashMap();static { Properties props = new Properties(); StringBuffer whiteList = new StringBuffer(); try { //读取上传配置文件 ClassPathResource classPathResource = new ClassPathResource("/fileUpload.properties"); InputStream in = classPathResource.getInputStream(); InputStreamReader ins = new InputStreamReader(in, "UTF-8"); props.load(ins); in.close(); ins.close(); } catch (IOException e) { e.printStackTrace(); //logger.info("读取配置文件 fileUpload.properties 失败,格式不正确!"); } Iterator<Map.Entry<Object, Object>> it = props.entrySet().iterator(); while (it.hasNext()) { Map.Entry<Object, Object> entry = it.next(); String key = entry.getKey() == null ? "" : entry.getKey().toString(); String value = entry.getValue() == null ? "" : entry.getValue().toString(); if (StringUtils.isNotBlank(key)) { //获取上传参数 if (key.startsWith("upload") && key.indexOf(".") != -1) { String[] keys = key.split("\\."); if (keys.length >= 2) { uploadParamsMap.put(keys[1], value); } } } } } }
