Java 通过 jquery 传递数组

Question

我有以下操作

 @RequestMapping(value = "info_pure", method = RequestMethod.GET)
    public ModelAndView GetInfo(String ser_name, String[] p_input_week_days, int p_input_month_day) {
        ModelAndView mav = new ModelAndView(JspView.PureInfoAup);       
        String aaa = request.getParameter("p_input_week_days");

我通过 jquery ajax 向此操作发送 get 请求。

 var myarray = ['Element 1', 'Element 2', 'Element 3'];

        var dataobject = {
            ser_name: p_ser_name.trim(), p_input_week_days: myarray, p_input_month_day: p_month_day
        };

        $.ajax({
            url: '../info_pure',
            data: dataobject,
            type: 'GET',
            success: function(data) { /// go forward

但是当请求发送时它给我一个错误。它说我的数组参数为空

这是我在 firebug 上的结果

使用 Spring MVC @RequestParam 注解。

@RequestMapping(value = "info_pure", method = RequestMethod.GET)
public ModelAndView GetInfo(@RequestParam("p_input_week_days[]") String[] days) {   
    String[] aaa = days;
