数据传递之前，先对中文进行编码，如下红色字体：

function saveCommentTemplate(){    $.ajax({        cache : false,        type:'get',        dataType:'json',            url:'comment/insert',            contentType:'application/json;charset=UTF-8',              data:{name:encodeURI($("#name").val()),                content:encodeURI($("#content").val())},        success:function(data){            alert("ok")         },        error: function() {              alert("error")          }      });    $("#bottom").hide();}

等数据传过来时，在对数据进行解码：

@RequestMapping(value = "insert")    @ResponseBody    public void insert(@RequestParam("name") String name,@RequestParam("content")String content) throws UnsupportedEncodingException    {        name=URLDecoder.decode(name,"UTF-8");        content=URLDecoder.decode(content,"UTF-8");        commentTemplateService.saveCommentTemplate(name,content);    }
