我收到一個錯誤在編譯成功時，在mybrowser中運行時出現了一個意外錯誤（type = Not Found，status = 404）錯誤。
爲什麼我的應用程序找不到我的jsp頁面？我應該包含哪些內容才能找到這些內容？我得到有一個意外的錯誤（type = Not Found，status = 404）錯誤？

如果從Eclipse中運行/ STS再檢查一次是否罐子實際拷貝到WEB_INF/lib目錄？您可以轉到服務器選項卡，右鍵單擊應用程序，然後單擊「瀏覽部署位置」。不知道爲什麼，但有時Eclipse不會複製它們。 –

謝謝！現在解決。 – bharat

你需要把@ResponseBody在你休息的方法。

這個標籤告訴Spring返回對象是響應的內容。

它沒有工作。你能解釋一下嗎？ – bharat

您已經將控制器標記爲RestController。 RestController標籤來自Spring 4.x，它已經包含ResponseBody。這是不好的答案它不會幫你... –

由於萊安德羅丹塔斯說你應該在你的休息方法上添加@ResponseBody。即

@RequestMapping(value="/events", 
     method=RequestMethod.GET 
     //produces=MediaType.APPLICATION_JSON_VALUE 
     ) 
@ResponseBody 
public ResponseEntity<Collection<events>> getEvents(){ 
    Collection<events> evnts = eventsservices.findAll(); 

    return new ResponseEntity<Collection<events>>(evnts,HttpStatus.OK); 

}

註釋，表示方法的返回值應綁定到該網絡響應體link

不，這是不好的答案，RestController已經包含ResponseBody它是多餘的... –

我得到有一個意外的錯誤（type = Not Found，status = 404）錯誤？
