代碼如下。兩種方法可以解決。
1.
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println(" <HEAD><TITLE>中文亂碼解決</TITLE></HEAD>");
out.println(" <BODY>");
out.print(" This is ");
out.print(this.getClass());
--------------------------------------------------
code如下
/*
*解決辦法，就是将字元串str的格式轉換成别的格式，一般是gb1803就可以了。編碼格式自己選。
*/
String str="<center><p>哈哈哈哈 哈哈哈哈哈 哈哈哈哈哈</p></center>";
byte[] b = str.getBytes("gb18030");
str= new String(b,"iso8859-1");
out.println(str);
out.println(" </BODY>");
out.println("</HTML>");
out.flush();
out.close();
2.
-----------------------------------------------------------------------
* 第二招 就是一句話， response.setContentType("text/html;charset=GB2312"); 即可解決問題
*/
response.setContentType("text/html;charset=GB2312");
PrintWriter out= response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>JasperReports - Web Application Sample</title>");
out.println("<link rel=\"stylesheet\" type=\"text/css\" href=\"../stylesheet.css\" title=\"Style\">");
out.println("</head>");
out.println("<body bgcolor=\"white\">");
out.println("<span class=\"bnew\">JasperReports 提示資訊:</span>");
String str = "<center><p><pre style='color:red;border=2px'>報表伺服器正在處理其他檔案，請您稍後重試。</pe> </p></center>";
out.println("</body>");
out.println("</html>");
out.close();
3.我将自己的源碼全拿出來，你們自己試吧，總能搞定的。搞不定了繼續百度。。
public voiddoGet(HttpServletRequest request, HttpServletResponse response)throwsServletException, IOException {
/*第一招
response.setContentType("text/html");
//out.println("<meta http-equiv=\"content-type\" content=\"text/html; charset=GB18030\">") ;
out.println(" <HEAD><TITLE>劉振宇</TITLE></HEAD>");
//String str= "";
//out.println(", "+str+" using the GET method");
*/
/*第二招
//response.setContentType("text/html");
response.setContentType("text/html;charset=GB2312");
//out.println("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=GB2312\">");
//out.println("<meta http-equiv=\"Content-Type\" contentType=\"text/html; charset=GB18030\">");
//response.setCharacterEncoding("gb2312");//設定PrintWriter的編碼
//response.setContentType("text/html;charset=utf-8");//可增加Content-Type頭字段
String str = "<center><p><pre style='color:red;border=2px'>報表伺服器正在處理其他檔案，請您稍後重試。</pe> </p></center>";
//e.printStackTrace(out);
}
*/
