本文介绍了一个使用Java实现的批量文件上传处理程序。该程序通过读取特定格式的文件列表，并利用HTTP客户端逐个发送这些文件到指定服务器进行上传。文章详细展示了如何构建HTTP请求、处理服务器响应以及记录错误的日志。

public static void main(String[] args) throws Exception{

if (args.length != 2){

System.out.println("Please enter feed file");

return;

}

String feedFileName = args[0];

String logFileName = args[1];

ObjectInputStream in = new ObjectInputStream(new FileInputStream(feedFileName));

File file = new File(logFileName);

if (file.exists()){

file.delete();

}

FileOutputStream out = new FileOutputStream(logFileName);

PrintWriter log = new PrintWriter(out);

try{

ArrayList arrayList = (ArrayList)in.readObject();

for (int i = 0 ; i < arrayList.size() ; i++){

PAReportUploadInfoVO paReportUploadInfoVO = (PAReportUploadInfoVO)arrayList.get(i);

try{

HttpClient client = new HttpClient();

PostMethod m = new PostMethod(url);

prepare(m, paReportUploadInfoVO);

int rc = client.executeMethod(m);

BufferedReader r = new BufferedReader(new InputStreamReader(m.getResponseBodyAsStream()));

String reply;

boolean hasError = true;

while ((reply = r.readLine()) != null){
