1.问题描述
JAVAWEB程序中，使用String输出中文，浏览器产生了乱码格式：
@Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String data = "中华人民共和国"; PrintWriter out = response.getWriter(); out.println(data); }
浏览器输出：🤷♂️🤷♂️
2.解决方法
设置请求和响应的字符编码格式为utf-8即可：
@Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //加入了如下行 request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); String data = "中华人民共和国"; PrintWriter out = response.getWriter(); out.println(data);
上述方法行不通？
换这个试试：
response.setContentType("text/html;charset=utf-8");
