Question

如果我在eclipse中作为java应用程序运行没有问题但是如果我导出为可运行的jar文件项目我得到编码问题？

如果它从eclipse运行，我可以通过套接字读取来自服务器的字符“ş”。如果它作为一个可运行的jar运行，我无法阅读char“ş”

我该如何解决这个问题？

修改

public class Start {

     public static void main(String[] args) {


               byte[] buff = new byte[1024];
               Socket socket = null;
               InputStream in = null;

               try {
                    socket = new Socket("11.11.11.11");
                    in = socket.getInputStream();

               } catch (IOException e) {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
               }

               try {
                    in.read(buff);

               } catch (IOException e) {
                     e.printStackTrace();
               } 

               System.out.println(new String(buff));




    }

}

使用当前平台的默认编码创建字符串。这在Eclipse和Eclipse之外可能有所不同。

改为使用

new String(buff)

指定字节数组应始终被视为UTF-8（假设它是您正在接收的UTF-8）

另外别忘了关闭你的溪流。

在导出到JAR时，从套接字读取编码字符不起作用
