我花了一段时间阅读其他文章，似乎没有人和我有同样的情况。我尝试了所有未读的解决方案，但没有结果，因此决定创建这个问题。
我一直在处理服务器/客户端应用程序，并且客户端似乎不从套接字读取数据，但是服务器可以读取客户端发送的数据。客户端在尝试读取该行时冻结。这是我的代码：
客户：
import java.io.IOException;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.Scanner;
import java.util.Timer;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JLabel;
public class Main {
public static Socket s = connect();
public static void sendMessage(String msg) {
if (s != null) {
PrintWriter outWriter = null;
try {
outWriter = new PrintWriter(s.getOutputStream(), true);
outWriter.println(msg);
outWriter.flush();
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
outWriter.close();
} finally {
}
} else {
System.err.println("Error, socket is null!");
}
}
public static String readMessage() { …这是问题所在.
首先,我在MySQL中创建了一个数据库
CREATE TABLE Users (User TEXT, Pass TEXT, ID TEXT, RegDate TEXT, Email TEXT, Rank TEXT);
我现在有这个数据库
+-----------+------------------+------------+----------+-------------------+------------+
| User | Pass | ID | RegDate | Email | Rank |
+-----------+------------------+------------+----------+-------------------+------------+
我使用导入了一个csv文件(Users.csv)(UTF-8,PlainText)
load data local infile 'Users.csv' into table Users fields terminated by ',' enclosed by '"' lines terminated by '\n';
该文件的内容是
arinerron,asdfasdf,USR0000001,92082015,arinesaugmail,Owner
looy,asdfasdf,USR0000002,92082015,tjesaugmail,User

它的回应是
Query OK, 6 rows affected (0.00 sec)
Records: 6 Deleted: 0 Skipped: 0 Warnings: 0
我跑了命令
SELECT * from …
