servlet学习笔记之四

要想get和post不出乱码 两种解决方式

一是server.xml中

 

 <Connector port="80" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" URIEncoding="GBK"/>

URIEncoding="GBK" //这行是后添加的

 

二是在代码中加

 

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html;charset=GBK");
        //解决post方式提交内容的乱码
        //一定要写在存取第一个参数之前
        request.setCharacterEncoding("GBK");
        
        //解决get方式乱码问题：-->URIEncoding="GBK"
        
        PrintWriter out = response.getWriter();
        out.println(request.getParameter("param1"));
        out.println("<br>");
        out.println(request.getParameter("param2"));
        out.println("<br>");
        out.println(request.getParameter("param3"));
        out.println("<br>");
        System.out.println("in doGet");
    }
