java - 从 Tomcat Servlet 中读取韩文字符

Question

我的服务器无法通过 POST 请求接收韩文字符，也无法将它们写入控制台。

这是我的代码:

protected void doPost(HttpServletRequest request,
        HttpServletResponse response) throws IOException {
    request.setCharacterEncoding("UTF-8");
    PrintWriter out = response.getWriter();

    StringBuffer buffer = new StringBuffer();
    String line = null;
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null)
        buffer.append(line);
    String requestMessage = buffer.toString();

    //working
    System.out.println("teniszütő");
    //not working (???????)
    System.out.println("\uc548\ub155\ud558\uc138\uc694\uc138\uacc4");
    //not working (??)
    System.out.println("여니");
    //accents are working, Korean characters aren't
    System.out.println(requestMessage);
    //writing 3F (the code of the ? instead of the code of the character)
    System.out.println(bytesToHexString(requestMessage.getBytes()));

    out.println("Answer");

}

我使用 Eclipse，如果我检查项目的属性，我可以看到“文本文件编码”是“从容器 (UTF-8) 继承”。如果我制作一个普通的 HelloWorld 应用程序(具有相同的设置)，它会打印韩文字符。

谢谢你的帮助!

我找到了解决方案。我必须在我的 <Connector> 中设置 URIEncoding="UTF-8"在 server.xml 中是这样的:

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443"
           URIEncoding="UTF-8"                 />
