编辑——我已经包括了一些测试类。遗憾的是，对于这些测试文件，服务器没有将任何数据写入它从客户端接收的文件中。我也不知道为什么。这是我能给atm的最好的。再次编辑-另外，我注意到在测试时，客户端将读取测试文本文件并在终端中打印。但是如果我在测试文本文件中添加新文本，它仍然会读入旧数据。也许是因为它在 Eclipse 目录中，idk。
服务器- http://pastebin.com/F7xzMdes
SeverMultiCLient - http://pastebin.com/HQM7PyGj
客户端 - http://pastebin.com/hBSLZsus
该程序的目标是让客户端将数据写入文件。客户端写入了 2 个文件。然后客户端将读取第一个文件的每一行并将其发送到服务器。然后服务器会将每一行写入自己的文件。这对第二个文件再次重复。
什么在起作用？：
客户端将所有数据写入其文件
客户端在发送到服务器之前读取每一行类型（一些小问题）
服务器正在写入数据（错误数据）
服务器正在将数据写入正确的文件
什么不工作？：
服务器没有将正确的数据写入其文件 - 这就是问题所在。它一遍又一遍地重复同一行编辑：真正的问题是它不断从客户端获取的字符串一遍又一遍。
要比较的文件：
以下 2 个链接应该匹配（除了第一行） 注意服务器有一个额外的行和重复的数据
客户的鼠标坐标http://pastebin.com/RnEGgBJm
服务器的鼠标坐标http://pastebin.com/cBqfLHnf
以下 2 个链接包含终端会话
服务器从客户端读取的每一行。这是写入服务器文件的内容，这应该与客户端的终端会话http://pastebin.com/A4xqWGiu匹配
客户端在发送到服务器之前从其文件中读取的每一行。发送的相同变量将打印到其终端。对不起图片。注意 2 个空值。不知道为什么那些在那里。 http://i.imgur.com/HTPVzHU.png
这是来自客户端的实际 sendData()
//This method will send data to the Client
public void sendData(Object[] data){
try {
oos.writeObject(data);
} catch (IOException e) {
e.printStackTrace();
}
}
客户端用于向服务器发送数据的代码。（getProgramPath() 是返回正确的路径顺便说一句）顺便说一句，代码的两个部分都发送重复数据
private static void sendSavedData(){
try {
System.out.println("CLIENT SEND SAVED DATA: " + getProgramPath() + savedDataFileName + ext);
} catch (IOException e1) {
e1.printStackTrace();
}
//Now send selection data to the server
Object[] selectionData = new Object[2];
selectionData[0] = "Selections";
//selectionData[1] = allGraphs;
BufferedReader br = null;
try {
br = new BufferedReader(new FileReader(getProgramPath() + savedDataFileName + ext));
String line = br.readLine();
while (line != null) {
line = br.readLine();
selectionData[1] = line;
System.out.println("Client Line: " + line);
sendData(selectionData);
}
}
catch(Exception e){
e.printStackTrace();
}
finally {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
//Now send selection mouse coor data to the server
selectionData = new Object[2];
selectionData[0] = "MouseCoor";
selectionData[1] = "Test here 1";
br = null;
try {
br = new BufferedReader(new FileReader(getProgramPath() + savedDataFileNameMouse + ext));
String line = br.readLine();
while (line != null) {
line = br.readLine();
selectionData[1] = line;
System.out.println("Client Line: " + selectionData[1]);
sendData(selectionData);
}
}
catch(Exception e){
e.printStackTrace();
}
finally {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
代码客户端用于将文件写入硬盘然后发送
public static void writeSavedFile(String line, int typeOfData){
if(typeOfData == 0){
FileWriter fstream;
try {
fstream = new FileWriter(getProgramPath() + savedDataFileName + ext, true); //Prepare to append (the "true") to the file
BufferedWriter out = new BufferedWriter(fstream); //More prep
out.write(line); //Write data
out.newLine(); //Write a new line
out.close(); //Close the file
} catch (Exception e) {
e.printStackTrace();
}
}
else if(typeOfData == 1){
FileWriter fstream;
try {
fstream = new FileWriter(getProgramPath() + savedDataFileNameMouse + ext , true); //Prepare to append (the "true") to the file
BufferedWriter out = new BufferedWriter(fstream); //More prep
out.write(line); //Write data
out.newLine(); //Write a new line
out.close(); //Close the file
} catch (Exception e) {
e.printStackTrace();
}
}
}
服务器使用读取数据的代码 - 它再次写入正确的文件，只是错误的数据。因此，如果需要，它将正确到达 Selections if 和 MouseCoor。此设置是 fromClient[0] 包含一个标签（选择、MouseCoor 等），而 fromClient[1] 包含要写入的数据。
while(true){
try{
if((fromClient = (Object[]) ois.readObject()) != null){
//Determine what data this is
String tag = (String)fromClient[0]; //Getting the tag
if(tag.equals("ID")){
Server.addClient(serverID, (String)fromClient[1]);
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");
Date date = new Date();
savedDataFileName = "Server Data - Selections - " + (String)fromClient[1] + " - " + dateFormat.format(date); //The new outputfile name
writeSavedFile("Server Data - Selections - " + (String)fromClient[1] + " - " + dateFormat.format(date),0);
//Now write the mouse coor file
savedDataFileNameMouse = "Server Data - Mouse Coor - " + (String)fromClient[1]; //The default naming for the outputfile
//The file will be saved with the date and time
savedDataFileNameMouse = "Server Data - Mouse Coor - " + (String)fromClient[1] + " - " + dateFormat.format(date); //The new outputfile name
writeSavedFile(savedDataFileNameMouse, 1);
}
else if(tag.equals("Selections")){
System.out.println("Server Line: " + (String)fromClient[1]);
writeSavedFile((String)fromClient[1], 0);
}
else if(tag.equals("MouseCoor")){
System.out.println("Server Line: " + (String)fromClient[1]);
writeSavedFile((String)fromClient[1], 1);
}
else{
System.out.println("WARNING - UNKNOWN DATA RECEIVED");
}
}
}
代码服务器用于写入文件
//Write saved data: 0 = Selections 1 = Mouse Coor
public static void writeSavedFile(String line, int typeOfData){
if(typeOfData == 0){
FileWriter fstream;
try {
fstream = new FileWriter(Server.getProgramPath() + savedDataFileName + ext, true); //Prepare to append (the "true") to the file
BufferedWriter out = new BufferedWriter(fstream); //More prep
out.write(line); //Write data
out.newLine(); //Write a new line
out.flush();
out.close(); //Close the file
fstream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
else if(typeOfData == 1){
FileWriter fstream;
try {
fstream = new FileWriter(Server.getProgramPath() + savedDataFileNameMouse + ext , true); //Prepare to append (the "true") to the file
BufferedWriter out = new BufferedWriter(fstream); //More prep
out.write(line); //Write data
out.newLine(); //Write a new line
out.close(); //Close the file
fstream.close();
} catch (Exception e) {
e.printStackTrace();
}
