关于项目自动化测试架构的改良计划-读取原始xml文件

按照我们的架构,第一步是读取原始的xml文件到一个xml字符串中:

创新互联公司专注于企业全网营销推广、网站重做改版、赣榆网站定制设计、自适应品牌网站建设、H5建站购物商城网站建设、集团公司官网建设、外贸网站制作、高端网站制作、响应式网页设计等建站业务,价格优惠性价比高,为赣榆等各大城市提供网站开发制作服务。

        BufferedReader reader = null;
        try {
                                        
            fis = new FileInputStream(file);
            isr = new InputStreamReader(fis, "utf-8");
            reader = new BufferedReader(isr);
            StringBuffer bufferedFileContent = new StringBuffer();
            String line = null;
            while ((line = reader.readLine()) != null) {
                bufferedFileContent.append(line).append(LINE_SEPARATOR);
            }
            return bufferedFileContent.toString();
        } catch (FileNotFoundException ex) {
            ex.printStackTrace();
            return null;
        } finally {
            if(reader!=null)
                reader.close();
            if(isr!=null)
                isr.close();
            if(fis!=null)
                fis.close();
        }
    }

代码很简单,就是一个基于文件流的操作,不再自己讲解。这个步骤对于架构图的第一步。
