Spring MVC之@RequestMapping 传递数组

1、前台：

var param = {titles:['col1','col2','col3']};

$.ajax({url:url, type:"post", data:param, async:false, dataType:"json", cache:false, error:function (data) {

        rtnObj = data.responseText;

    }, beforeSend:function (XMLHttpRequest) {

        //ajaxStart();

    }, complete:function (XMLHttpRequest, textStatus) {

        //ajaxComplete();

    }, success:function (data) {

        rtnObj = data;

    }});  

2、后台：

@RequestMapping(value="/exportExcel", method = RequestMethod.POST)

    @ResponseBody

    public String exportExcel(@RequestParam(value = "titles[]") String[] titles){

        System.out.println(titles);

        return null;

    }
