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;
    }
