Java/Guice錯誤配置類MyExample.GuiceServletConfig的應用程序偵聽器

我試圖得到一個裸心的框架去，我有一些麻煩讓它實際運行。Java/Guice錯誤配置類MyExample.GuiceServletConfig的應用程序偵聽器

下面的文件都在 '示例' 包：

AbstractController.java

package example; 

import java.io.IOException; 

import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import com.google.inject.Singleton; 


@Singleton 
@SuppressWarnings("serial") 
public abstract class AbstractController extends HttpServlet { 
    @Override 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
    } 
    @Override 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     doGet(request, response); 
    } 
}

ApplicationInitializer.java

package example; 

import com.google.inject.Inject; 
//import com.google.inject.persist.PersistService; 

public class ApplicationInitializer { 
    @Inject 
    ApplicationInitializer() { 
     // stuff comes here later 
    } 
}

GuiceServletConfig.java

package example; 

import com.google.inject.Guice; 
import com.google.inject.Injector; 
import com.google.inject.servlet.GuiceServletContextListener; 
import com.google.inject.servlet.ServletModule; 

public class GuiceServletConfig extends GuiceServletContextListener {  
    @Override 
    protected Injector getInjector() { 

     Injector injector = Guice.createInjector(new ServletModule() { 
      @Override 
      protected void configureServlets() {   

       // direct to servlets 
       serve("/Example").with(ServerController.class); 
       serve("/*").with(ServerController.class); 


      } 
     }/*, new ProductionModule()*/); 

     injector.getInstance(ApplicationInitializer.class); 

     return injector; 
    } 

}

ProductionModule.java

package example; 

import com.google.inject.AbstractModule; 

public class ProductionModule extends AbstractModule { 
    @Override 
    protected void configure() { 
     // stuff comes later 
    } 
}

ServerController.java

package example; 

import java.io.IOException; 

import javax.servlet.ServletException; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import com.google.inject.Singleton; 

@Singleton 
@SuppressWarnings("serial") 
public class ServerController extends AbstractController { 

    //@Inject 
    public ServerController() { 
     // future dependencies 
    } 

    @Override 
    protected void doGet(HttpServletRequest request, 
      HttpServletResponse response) throws ServletException, IOException { 

     request.getRequestDispatcher("WEB-INF/pages/test.jsp").forward(request, response); 
    } 

}

我已經添加了以下到我的web.xml中，靠近頂部：

<filter> 
    <filter-name>guiceFilter</filter-name> 
    <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> 
    </filter> 

    <filter-mapping> 
    <filter-name>guiceFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
    </filter-mapping> 

    <listener> 
     <listener-class>example.GuiceServletConfig</listener-class> 
    </listener>

但由於某些原因，我得到以下堆棧跟蹤：（Tomcat上運行，作爲服務）

我已經一段時間了排除此爲一個偉大的，很想得到它實際上做除了拋出異常之外的東西。有任何想法嗎？

由於錯誤說：

SEVERE: Error configuring application listener of class MyExample.GuiceServletConfig 
    java.lang.ClassNotFoundException: MyExample.GuiceServletConfig

你的聽衆不存在：

<listener> 
    <listener-class>MyExample.GuiceServletConfig</listener-class> 
</listener>

錯誤的包;如您所述，您的課程全部位於example包中。

謝謝，這絕對是一個錯誤的東西，但將其改爲@ example.GuiceServletConfig令人驚訝地產生相同的堆棧跟蹤。任何線索？ – abanana

@abanana假設這是一個拼寫錯誤，那麼你沒有正確地部署它，因爲如果你改變了配置並正確部署了它，它不能產生相同的堆棧跟蹤。 –

@abanana或者該服務需要重新啓動以獲取新的配置等。 –
