Fuck you Ie 使用produces設置返回類型

錯誤背景：

前端作文件上傳採用了jquery.form.js的ajaxSubmit方法，該方法可實現頁面無刷新提交form表單以及文件上傳。功能開發所用瀏覽器是谷歌，可是由於要求最低兼容ie8，功能開發完畢後，谷歌下完美運行，可是在ie8兼容模式下，卻報錯了，點了保存按鈕後，數據提交到了後端，後端報錯了，前端瀏覽器也由於後端報錯沒法返回，控制檯也出現了錯誤信息。錯誤信息以下：

錯誤解決：

　　一開始看到ie報錯，第一反應是js不兼容，好比jquery版本或者jquery.form.js版本不兼容，一度試圖更換版本。

　　聽說jq2.0以上都再也不支持ie8 個人jq是在2.0如下。

　　聽說ie在在上傳文件的時候回出現下載框，是響應類型沒有設置，在後端獲取到httpservletresponse對象，而後設置響應類型爲text/json.可是依然沒用

　　而後就瘋狂翻帖子 找解決辦法，終於看到一個大神說設置  produces="text/json"

　　

 

RequestMapping中produces屬性做用

　　註解RequestMapping中produces屬性能夠設置返回數據的類型以及編碼，能夠是json或者xml：

@RequestMapping(value="/xxx",produces = {"application/json;charset=UTF-8"})
或
@RequestMapping(value="/xxx",produces = {"application/xml;charset=UTF-8"})

　　可是必需要和@ResponseBody註解一塊兒使用才能夠，不加@ResponseBody註解至關於按照和返回String同名jsp頁面解析天然就會報錯。
