eclipse 执行out.request()方法提示out cannot be resolved

添加代码：PrintWriter out = response.getWriter();

支持中文：response.setContentType("text/html;charset=utf-8");

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
PrintWriter out = response.getWriter();
response.setContentType("text/html;charset=utf-8");
out.println("<h1>您好，我叫张荟子</h1>");

}
