彈性配置問題 - 無法加載應用程序類

以及我試圖添加Spring依賴項注入到我的項目，因爲我添加了所有需要的東西春集成到我的項目中，Web項目無法部署... 爲什麼我認爲它與我的Spring配置有關？那麼之前添加任何彈簧的配置Vaadin GUI，servlet的完美部署，並因此做了球衣REST Web服務...彈性配置問題 - 無法加載應用程序類

現在試圖運行它時，我得到這個錯誤：

我嘗試刪除球衣web服務servlet部分，但它仍然無法加載vaadin前端servlet，如果你需要沒有球衣的錯誤，我可以發佈它，但我認爲這不是必要的。

的webservice類看起來像這樣：

import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.PathParam; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.beans.factory.annotation.Qualifier; 
import org.springframework.stereotype.Service; 

import com.nortal.pirs.businesslogic.factories.ControllerFactoryProvider; 
import com.nortal.pirs.businesslogic.interfaces.UserManagerInterface; 

@Path("/emailcheck/{emailAddress}") 
public class EmailCheckService { 

    //@Autowired 
    //@Qualifier("UserManager") 
    private UserManagerInterface userManager = ControllerFactoryProvider.getInstance().createUserManager(); 

    @GET 
    @Produces(MediaType.APPLICATION_JSON) 
    public String emailExists(@PathParam("emailAddress") String email) { 
     if (userManager.emailExists(email)) { 
      return "true"; 
     } else { 
      return "false"; 
    } 
    } 

    public void setUserManager(UserManagerInterface userManager) { 
     this.userManager = userManager; 
    } 
}

有人來過這種問題嗎？我認爲這是因爲我在配置中添加了spring，但是即使我刪除它，它似乎也不起作用，實際上web.xml中的任何東西現在似乎都不起作用......也許這是Tomcat的東西？我正在使用在Eclipse中配置的Tomcat 7。我試圖清理它，但它似乎也沒有幫助。我很困惑。

Jersey無法找到任何可以作爲Jersey RESTful Web服務執行的類。

檢查：

無論com.sun.jersey.config.property.packages中缺少您的web.xml - 似乎確定。
com.sun.jersey.config.property.packages param值是否丟失或無效 - 我無法確定。
是否至少有一個POJO有一個註解爲@Path的方法 - 我看不出來。
如果此異常的many Google hits可以幫助您進一步處理。

那麼我編輯並提供了web服務文件，但即使沒有web服務web部件。xml它仍然無法部署。這不是春天，因爲誠實，沒有什麼在web.xml中似乎現在工作... –

您可以驗證您的Resource類是否位於您的web.xml中定義的此包中（com.nortal.pirs.webservices）？您的服務器日誌表明無法找到資源類別。假設該軟件包包含Resource類，則服務器日誌將顯示這些類的列表。我有一個同時使用Spring和Jersey的項目，沒有問題。

也許，您可能想要在您的web.xml中禁用servlet和servlet-mapping的PirsVaadinFrontend，並首先調試Jersey錯誤。你在這裏有兩個不同的錯誤，我不能確定是否是導致其他問題的一個問題，或者如果你有兩個獨立的問題。

那麼我編輯我的問題與該文件的代碼，你可以看到它在該包。事情是，它確實有效，我沒有改變軟件包的結構。然而，有一件事我錯了。它不能是Spring，因爲我已經刪除它，但它仍然是一樣的，所以以前的工作，現在根本不起作用。它也說：javax.servlet.ServletException：無法加載應用程序類：com.nortal.pirs.presentation.vaadin.PirsVaadinController我在我的問題中有一個。我主要懷疑它是一個問題，那麼阻止servlet被部署的問題 –
