ajax 請求後台資料返回異常 及 提示404方法名不存在

標籤：

1、正常使用 Ajax 調取後台資料時，提示方法名不存在，Ajax前端正常，方法類bean注入正常，方法註解正常。但參數解析時出現異常。

@RequestMapping(value="/getProject")@ResponseBodypublic Map<String,Object> getProject(@RequestBody Map<String, Object> paraMap,HttpServletRequest request){Map<String, Object> map = new HashMap<String, Object>();String projectName = (String)paraMap.get("projectName");

　　強轉時出現了異常，未被捕獲。具體為什麼這個異常會影響request解析暫時還不曉得，有哪位大神知道的請留言解釋一下，謝謝。

2、方法正常流轉之後無法將資料直接返回頁面。提示異常如下：

　　網上搜查相關資料說是重複提交了資料。檢查前端發現，綁定點擊事件的按鈕前多加了個<a href=""> 。這個href=“” 影響了response跳轉導致。

鬱悶筆記下這些“事故”故事，緬懷（調試之痛苦）謹記（簡單BUG浪費時間）之……………………
