Properties props = new Properties();InputStream fis = new FileInputStream("MsgConfig.properties");//从输入流中读取属性列表(键和元素对)props.load(fis);fis.close();//一定要在修改值之前关闭fisOutputStream fos = new FileOutputStream("MsgConfig.properties");props.setProperty("ismgIp",form.getConfig().getIsmgIp() );props.store(fos, "Update '" + "ismgIp" + "' value");props.setProperty("sharedSecret",form.getConfig().getSharedSecret() );props.store(fos, "Update '" + "sharedSecret" + "' value");props.setProperty("spId",form.getConfig().getSpId() );props.store(fos, "Update '" + "spId" + "' value");props.setProperty("ismgPort", form.getConfig().getIsmgPort());props.store(fos, "Update '" + "ismgPort" + "' value");props.setProperty("spCode", form.getConfig().getSpCode());props.store(fos, "Update '" + "spCode" + "' value");props.setProperty("timeOut", form.getConfig().getTimeOut());props.store(fos, "Update '" + "timeOut" + "' value");props.setProperty("connectCount",form.getConfig().getConnectCount() );props.store(fos, "Update '" + "connectCount" + "' value");fos.close();直接输出是修改了,但是配置文件里面的内容又没改过来
