PUT和POST獲取405方法不允許錯誤的Restful Web服務

Question

我想設置一個簡單的Restful Web服務，根據Accept標頭返回JSON或XML。我正在使用Spring，Maven和WebLogic Server。我從這篇文章http://software.sawano.se/2012/03/combining-json-and-xml-in-restful-web.html中拿出了這個例子，並試圖改進它。 GET和DELETE同時適用於JSON和XML.BUT和POST會給出「405方法不允許」的錯誤。我正在嘗試使用Chrome擴展高級休息客戶端進行測試。下面是Response頭。

，我給請求體低於：現在我沒有在放東西

    System.out.println("Inside the put function"); 
     if(temp==null){System.out.println("This is a Null for PUT");} 
} 
} 

：如下圖所示

{ 
id: 1 
name: "manga" 
} 

我的控制器類。

好吧，顯然我不得不改變我的PUT調用函數updateUser。我刪除了@Consumes，@RequestMapping並且還添加了@ResponseBody該函數。所以我的方法是這樣的：

@RequestMapping(value="/{id}",method = RequestMethod.PUT) 
@ResponseStatus(HttpStatus.OK) 
@ResponseBody 
public void updateUser(@PathVariable int id, @RequestBody User temp){ 
    Set<User> set1= obj2.getUsers(); 
    for(User a:set1) 
    { 
     if(id==a.getId()) 
     { 
      set1.remove(a); 
      a.setId(temp.getId()); 
      a.setName(temp.getName()); 
      set1.add(a); 
     } 
    } 
    Userlist obj3=new Userlist(set1); 
    obj2=obj3; 
} 

它的工作！謝謝大家的迴應。

通知允許的方法在響應

Connection: close 
Date: Tue, 11 Feb 2014 15:17:24 GMT 
Content-Length: 34 
Content-Type: text/html 
Allow: GET, DELETE 
X-Powered-By: Servlet/2.5 JSP/2.1 

只接受GET和DELETE。因此，您需要調整服務器以啓用PUT和POST。

Allow: GET, DELETE

我不知道如果我是正確的，但是從請求頭，你後：

請求頭

接受：應用/ JSON

產地：chrome-extension：// hgmloofddffdnphfgcellkdfbfbjeloo

User-A gent：Mozilla/5.0（Windows NT 6.1; WOW64）爲AppleWebKit/537.36（KHTML，例如Gecko）鉻/ 29.0.1547.76 Safari瀏覽器/ 537.36

內容類型：應用/ X WWW的窗體-urlencoded

接受編碼：gzip，放氣， sdch Accept-Language：en-US，en; q = 0.8

好像你沒有將你的請求體配置成JSON類型。
