SpringMVC接收參數的註解筆記

1.@RequestParam

    var param = {};
    param.keys = delKeys.join();//delKeys是數組，如delKeys=['a',b','c'],join函數把數組拼接成字符串，分隔符默認是,
    $.ajax({
        type: "POST",
        data: param,
        dataType: "json",//預期服務器返回的數據類型
        url: ctxpath+"/cache/deleteCache.action",
        success: function (serverData) {
            alertWin("成功刪除"+serverData.data+"條");
            search();
        }
    });

@RequestMapping("/deleteCache.action")@ResponseBodyprivate PageResponse deleteCache(HttpServletRequest request,@RequestParam List<String> keys) {　　//keys能夠獲得正確的數組　　//request.getParameter("keys")　獲得的是"a,b,c"}
