球衣測試框架灰熊返回404 not found錯誤

Question

我想在我的應用程序中實現針對Jersey REST / Json的JUnit測試。

我的問題是我沒有從Grizzly找回404。 但是路徑是正確的，並且可以在普通Webcontainer上使用Curl進行測試。

我正在使用GWTP（沒有maven）。 我正在手動實現屬性-> Java Build Path。 我正在使用以下版本：

• Eclipse Indigo（在Windows 7上）
• ASM-3.3.1.jar
• 新澤西州的客戶 - 1.12.jar
• 新澤西州的核心1.12.jar
• 新澤西州JSON-1.12.jar
• 新澤西服務器1.12.jar
• 新澤西州的servlet-1.12.jar
• 球衣測試框架 - 核心1.12.jar
• 球衣測試框架，灰熊，1.12.jar
• 灰熊框架，1.9.45.jar
• Grizzly的HTTP-1.9.45.jar
• Grizzly的HTTP-servlet的1.9.45.jar
• 灰熊-portunif-1.9.45.jar
• 灰熊-RCM-1.9.45.jar
• 灰熊-servlet的Web服務器，1.9.45.jar
• 灰熊-utils的-1.9.45.jar
• servlet的API-2.5.jar
• junit-4.9.jar（還與4.10.jar一起測試）

根據Jersey文檔提供了所有庫： http : //jersey.java.net/nonav/documentation/latest/user-guide.html-第7.5章在Maven外部運行測試。

以下是堆棧跟蹤：

我的課程如下所示：

當將應用程序作為Web Appliction運行時，使用Curl和以下命令進行測試可以工作：

curl http://localhost:8888/api/cards -i -X POST -H "Content-Type: application/json" -d "{\"id\": \"1\", \"name\": \"Name of Card\", \"code\": \"123456\", \"codeTypeId\": \"1\", \"cardProviderName\": \"Card Provider\", \"picturePath\": \"provider.jpg\", \"cardProviderUrl\": \"http://www.provider.com\", \"creationDate\": \"Sun Jun 10 08:55:14 UTC 2012\", \"modificationDate\": \"Sun Jun 10 08:55:14 UTC 2012\" }"

我什至嘗試用RawCap.exe嗅探回送接口。 我在PCAP文件中看到以下內容：

POST /api/cards HTTP/1.1
Content-Type: application/json
User-Agent: Java/1.7.0
Host: localhost:9998
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
Content-Length: 254

{"id":"1","name":"Name of Card","code":"123456","codeTypeId":"1","cardProviderName":"Card Provider","picturePath":"provider.jpg","cardProviderUrl":"http:\/\/www.provider.com","creationDate":"Sun Jun 10 08:55:14 UTC 2012","modificationDate":"Sun Jun 10 08:55:14 UTC 2012"}

HTTP/1.1 404 Not Found

server: grizzly/1.9.45
Content-Type: text/plain; charset=iso-8859-1
Transfer-Encoding: chunked
Date: Sun, 01 Jul 2012 00:02:16 GMT

在我看來，JSON字符串已提交到URL，但是找不到任何類。

我被卡在這里了一點。 我的上下文路徑一定做錯了，但是我不知道該怎么做以及如何設置它。

克里斯，謝謝你的幫助

當將應用程序作為Web應用程序運行時，它會基於web.xml在/ api / URL處公開。 Grizzly或輕量級HTTP服務器都無法識別web.xml，因此它們在容器根目錄公開jersey。
