在servlet中返回json数据

在servlet：

String name = new tring(request.getParameter("name").getBytes("iso8859-1"),"utf-8");

response.setCharacterEncoding("utf-8");

request.setCharacterEncoding("utf-8");

response.setContentType("application/json; charset=utf-8");

 //拼接json数据

String jsonStr = "{\"name\":\""+name+"\",\"age\":\"20\"}";

 //将数据写入流中

response.getWriter().write(jsonStr);

js：

<script>

    $(function(){

        $.post("${ pageContext.request.contextPath }/servlet/jsonServlet",{"name":"赵子龙"},function(result){

                        //遍历

            $.each(result, function(i, field){

              $("#divbox").append(i+":"+field + ";");

            });

        });

//         $.getJSON("${ pageContext.request.contextPath }/servlet/jsonServlet",function(result){

//             $.each(result, function(i, field){

//               $("#divbox").append(i+":"+field + ";");

//             });

//         });

    })

    </script>
