代码如下。两种方法可以解决。
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>中文乱码解决</TITLE></HEAD>");
out.println(" <BODY>");
out.print(" This is ");
out.print(this.getClass());
--------------------------------------------------
code如下
/*
*解决办法，就是将字符串str的格式转换成别的格式，一般是gb1803就可以了。编码格式自己选。
*/
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.
-----------------------------------------------------------------------
code如下
/*
* 第二招 就是一句话， response.setContentType("text/html;charset=GB2312"); 即可解决问题
*/
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 提示信息:</span>");
String str = "<center><p><pre style='color:red;border=2px'>报表服务器正在处理其他文件，请您稍后重试。</pe> </p></center>";
out.println(str);
out.println("</body>");
out.println("</html>");
out.flush();
out.close();
3.我将自己的源码全拿出来，你们自己试吧，总能搞定的。搞不定了继续百度。。
public voiddoGet(HttpServletRequest request, HttpServletResponse response)throwsServletException, IOException {
/*第一招
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
//out.println("<meta http-equiv=\"content-type\" content=\"text/html; charset=GB18030\">") ;
out.println("<HTML>");
out.println(" <HEAD><TITLE>刘振宇</TITLE></HEAD>");
out.println(" <BODY>");
out.print(" This is ");
out.print(this.getClass());
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);
//String str= "";
//out.println(", "+str+" using the GET method");
out.println(" </BODY>");
out.println("</HTML>");
out.flush();
out.close();
*/
/*第二招
//response.setContentType("text/html");
response.setContentType("text/html;charset=GB2312");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
//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");//设置PrintWriter的编码
//response.setContentType("text/html;charset=utf-8");//可增加Content-Type头字段
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 提示信息:</span>");
String str = "<center><p><pre style='color:red;border=2px'>报表服务器正在处理其他文件，请您稍后重试。</pe> </p></center>";
out.println(str);
//e.printStackTrace(out);
out.println("</body>");
out.println("</html>");
out.flush();
out.close();
}
