Spring MVC Controller 接收ajax的数组参数说明

/** * Created by xiongyu on 2017/5/12. */$(function () {  $("#deleteSelect").click(function () {      .......//省略部分代码        var res = $.ajax({            url: "/SpringMybatis/user/deleteBySelective",            data: {data: chk_value},              // traditional: true, 这里的取值后面说明            success: function () {                console.log(res.responseText)                loadData();            }, error: function () {                console.log(res.responseText)            }        })    });});

traditional默认是false,如果是false,则传递的参数为:data[]:1......这里设置为true,使传递参数变成:data:1......

若传递的数据格式是data[]:1,则RequestParam的value是data[], 若传递的数据格式是data:1,则RequestParam的value是data,后面既可以用List接收,也可以用数组接收.
以 traditional默认值时为例，controller代码为：

 @RequestMapping(value = "deleteBySelective", produces = "text/html;charset=UTF-8;")    @ResponseBody    public String deleteBySelective(HttpServletRequest request, Model   model,@RequestParam(value = "data[]")String[] data) {        System.out.println("request now is here");        System.out.println(Arrays.asList(data));        userService.deleteBySelective(Arrays.asList(data));        return "whatever you like";    }
