JAVA获取自定义配置文件的kv值

  /**
   * 读取 .properties 配置文件
   * @param propertiesUrl 配置文件的路径
   * @return 配置文件中的key-value值
   */
  public static Map getProperties(String propertiesUrl) {
    Map resultMap = new HashMap();
    Properties prop = new Properties();
    try {
      // 读取属性文件a.properties
      InputStream in = new BufferedInputStream(new FileInputStream(propertiesUrl));
      // 加载属性列表
      prop.load(in);
      Iterator it = prop.stringPropertyNames().iterator();
      while (it.hasNext()) {
        String key = it.next();
        resultMap.put(key, prop.getProperty(key));
        System.out.println("key: "+key+",      value: "+prop.getProperty(key));
      }
      in.close();
    } catch (Exception e) {
      System.out.println(e);
    }
    return resultMap;
  }

使用方式

String path =  System.getProperty("user.dir") + "\\conf\\303\\config.properties";
Map properties = TestUtil.getProperties(path);
System.out.println("哈哈哈" + properties.get("businessId"));
