方法一

$.ajax({
    url : "rest/lost/saveLost",
    type : "post",
    cache : false,
    dataType : 'json',
    data : $(form).serializeArray(),
    success : function(result) {
        if (result)
            alertConfirm("添加成功");
        else
            alertView("添加失败");
    },
});

后台java代码

@RequestMapping(value="/saveLost",method = RequestMethod.POST)
@ResponseBody
public boolean saveLost(@RequestParam("goodName") String goodName,
        @RequestParam("lostTime") String lostTime,
        @RequestParam(value = "place", required = false) String place,
        @RequestParam("descption") String descption,
        @RequestParam(value = "telephone", required = true) String telephone) throws ParseException{

    Lost lost = new Lost();
    lost.setDescption(descption);
    lost.setGoodName(goodName);
    Date time = (Date) Common.toDateStandard(lostTime);
    lost.setLostTime(time);
    lost.setTelephone(telephone);
    lost.setPeople(telephone);
    lost.setPlace(place);
    lost.setStates("0");
    try {
        lostServiceImpl.insert(lost);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return false;
    }
    return true;
}

方法二

function edit(oldValue){
    $.ajax({
        url:"rest/depart/edit",
        type:"post",
        cache:false,
        dataType:"json",
        contentType:"application/json; charset=utf-8",
        data:JSON.stringify(oldValue),
        success:function(result){
            if (result){
                alertView("修改成功");
                query(oldValue.descption);
            }            
            else
                alertView("修改失败");
        }
    })
}

@RequestMapping(value = "/edit",method=RequestMethod.POST)
@ResponseBody
public boolean edit(@RequestBody Object value) {

    JSONObject jsonObj = JSONObject.fromObject(value);//将json字符串转换为json对象
    Department depart = (Department) JSONObject.toBean(jsonObj,Department.class);//将建json对象转换为PublicGarden对象
    departServiceImpl.update(depart);
    return true;
}

直接上代码简单明了得意
