controller

@RequestMapping(value = "/com/testjson", produces = { "text/plain;charset=UTF-8" })
public @ResponseBody String testjson(HttpServletRequest request){
    Map<String,Object> m = new HashMap<String,Object>();
    ......
    return new JSONObject(m).toString();
}

頁面

$('#testFm').form('submit', {
    url : 'com/testjson',
    type : "POST",
    onSubmit : function() {
        ......
        return validate;
    },
    success : function(data) {
        data = $.parseJSON(data);
        ......
    }
});
