启动SpringMVC的注解功能，完成请求和注解POJO的映射

         
         
         
             
                  
                       
        
         text/html;charset=UTF-8

js

$.fn.serializeJson = function(){                var jsonData1 = {};                var serializeArray = this.serializeArray();                // 先转换成{"id": ["12","14"], "name": ["aaa","bbb"], "pwd":["pwd1","pwd2"]}这种形式                $(serializeArray).each(function () {                    if (jsonData1[this.name]) {                        if ($.isArray(jsonData1[this.name])) {                            jsonData1[this.name].push(this.value);                        } else {                            jsonData1[this.name] = [jsonData1[this.name], this.value];                        }                    } else {                        jsonData1[this.name] = this.value;                    }                });                // 再转成[{"id": "12", "name": "aaa", "pwd":"pwd1"},{"id": "14", "name": "bb", "pwd":"pwd2"}]的形式                var vCount = 0;                // 计算json内部的数组最大长度                for(var item in jsonData1){                    var tmp = $.isArray(jsonData1[item]) ? jsonData1[item].length : 1;                    vCount = (tmp > vCount) ? tmp : vCount;                }                if(vCount > 1) {                    var jsonData2 = new Array();                    for(var i = 0; i < vCount; i++){                        var jsonObj = {};                        for(var item in jsonData1) {                            jsonObj[item] = jsonData1[item][i];                        }                        jsonData2.push(jsonObj);                    }                    return JSON.stringify(jsonData2);                }else{                    return "[" + JSON.stringify(jsonData1) + "]";                }            };

修改的js，返回json的数组对象

$.fn.serializeJson = function(){    var jsonData1 = {};    var serializeArray = this.serializeArray();    // 先转换成Object{id:Array(2),name:Array(2),pwd:Array(2)}==>{"id": ["12","14"], "name": ["aaa","bbb"], "pwd":["pwd1","pwd2"]}这种形式,即属性数组形式    $(serializeArray).each(function () {        if (jsonData1[this.name]) {            if ($.isArray(jsonData1[this.name])) {                jsonData1[this.name].push(this.value);            } else {                jsonData1[this.name] = [jsonData1[this.name], this.value];            }        } else {            jsonData1[this.name] = this.value;        }    });    // 再转成[Object,Object]==>[{"id": "12", "name": "aaa", "pwd":"pwd1"},{"id": "14", "name": "bb", "pwd":"pwd2"}]的形式,即对象数组    var vCount = 0;    // 计算json内部的数组最大长度    for(var item in jsonData1){        var tmp = $.isArray(jsonData1[item]) ? jsonData1[item].length : 1;        vCount = (tmp > vCount) ? tmp : vCount;    }    var jsonData2 = new Array();    if(vCount > 1) {        for(var i = 0; i < vCount; i++){            var jsonObj = {};            for(var item in jsonData1) {                jsonObj[item] = jsonData1[item][i];            }            jsonData2.push(jsonObj);        }    }else{        jsonData2.push(jsonData1);    }    return jsonData2;//返回的是json的对象数组};

 

总结：最关键的是JS中的拼接json数据，ajax请求的属性以及后台接收的参数
