當(dāng)然也可以這樣子：

public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {response.setContentType("text/html;charset=utf-8");//這就是讓servlet以u(píng)tf-8解碼參數(shù)值，那么就可以直接得到正確的中文值了request.setCharacterEncoding("UTF-8");PrintWriter out = response.getWriter();String name = request.getParameter("name");double salary = Double.parseDouble(request.getParameter("salary"));int age = Integer.parseInt(request.getParameter("age"));System.out.println("name:"+name);System.out.println("salary:"+salary);System.out.println("age:"+age); }
