java 读取properties的方法，源码

首先 ，类开头写上 

private Properties properties = new Properties();

 

主方法里 这样写   String adds = getProperty("adds");

方法实现

public String getProperty(String name) {
  String adds = null;
  InputStream in = this.getClass().getResourceAsStream(
    "acpInterface.properties");
  if (in == null) {
   throw new RuntimeException("acpInterface.properties not found");
  }
  if (!(in instanceof BufferedInputStream))
   in = new BufferedInputStream(in);
  try {
   properties.load(in);
   adds = properties.getProperty(name);
   in.close();
  } catch (Exception e) {
   e.printStackTrace();
   throw new RuntimeException(
     "Error while processing acpInterface.properties", e);
  }
  return adds;
 }
