批量读文件为一个String（一个文件夹下的大量xml文件）

String folder =  " /nasapp/datamerger/xmls/ "  ;

        File file = new File(folder);

        if(!file.exists()){

            file.mkdir();

        }

        File[] files = file.listFiles();

        for(File f:files){

            try {

                if (f.isFile() && f.exists() && "xml".equals(f.getName().substring(f.getName().lastIndexOf(".")+1))) {

                    StringBuffer buffer = new StringBuffer();

                    String encoding = "UTF-8";

                    InputStreamReader read = new InputStreamReader(new FileInputStream(f), encoding);

                    BufferedReader bufferedReader = new BufferedReader(read);

                    String lineTxt = null;

                    while ((lineTxt = bufferedReader.readLine()) != null) {

                        buffer.append(lineTxt);

                    }

                    read.close();

                    

                    if(buffer!=null && StringUtils.isNotBlank(buffer.toString())){

                        String report = buffer.toString();}
