写入.properties
String path = ServletActionContext.getServletContext().getRealPath("");
??Properties properties = new Properties();
??try {
??????? InputStream inputStream = new FileInputStream(path+"/config.properties");
??????? properties.load(inputStream);
??????? OutputStream outputStream = new FileOutputStream(path+"/config.properties");

??????? props.load(in);
??????? String value = props.getProperty(key);
