我正努力讓Guice與我的澤西/灰熊課程一起工作。我從控制檯Java應用程序開始,添加了Guice,並使我的注入和我的域對象一起工作。然後我開始通過澤西/灰熊添加web服務。正如你可以從我的編碼風格中看出的那樣,我來自C#背景。所以我相信我的一些努力是學習Java的做事方式。Jersey Guice整合異常
我想要的是我的非webservices類可以注入web服務處理程序,以便他們可以使用我構建的功能。
在下面我的課,我有一個數據庫實例句柄我希望注入web服務類:
@Path("/options")
public class OptionsServices {
private IDatabaseService dbService;
@Inject
public void setService(IDatabaseService svc){
this.dbService = svc;
}
@GET
@Path("{symbol}")
@Produces(MediaType.APPLICATION_JSON)
public Quote getOptionQuote(@PathParam("symbol") String symbol) {
// do stuff
}
}
我嘗試添加在GuiceBridge和有約束力的,在我的擴展ResourceConfig類的。但是,無論我使用什麼版本,當我嘗試初始化Web服務時,都會遇到關於缺少屬性的非常瘋狂的例外情況。只需從我的pom.xml中刪除GuiceBridge即可刪除異常。這似乎是它的版本兼容性問題,但我不知道什麼版本的庫。

我很抱歉,我不能更明確的解釋這個問題,這裏的什麼是錯的。我可能已經將我的應用程序設計爲完全錯誤的,因爲這只是我的學習,我相信這一點。我想避免重寫我的域邏輯構造和單元測試。
謝謝您的幫助 馬特
這是一個很好的解釋。我很抱歉這是一個新手問題。我如何不使用BOM? – tatmanblue
@tatmanblue簡單。您刪除bom聲明併爲每個依賴項添加一個版本。物料清單只是一個_meta-dependency_,它爲您提供確切的版本。看看''沒有''的聲明。欲瞭解更多信息,請參閱[http://stackoverflow.com/questions/14874966/how-to-use-bom-file-with-maven](This問題)。 –
sargue
謝謝。刪除BOM,爲您的依賴項設置特定的版本號,就像您呼出的那樣,解決了我的問題。我現在能夠從瀏覽器訪問我的web服務而不會出錯(我必須爲json序列化添加一個依賴項) – tatmanblue
