Klassenpfadressource [applicationContext.xml] kann nicht geöffnet werden, da sie nicht mit java config existiert

Question

ich benutze spring 4.0.2, eclipse JEE marse, Tomcat v7.0. Ich habe ein Beispiel von here getestet. mein Projektstruktur ist:

Java Resources 
    src 
     com.test.config 
      HelloConfig.java 
      HelloController.java 
      HelloInitializer.java 
WebContent 
    META-INF 
     MANIFEST.MF 
    WEB-INF 
     lib 
     view 
      welcome.jsp 

Inhalt meiner HelloConfig.java ist:

package com.test.config; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.ImportResource; 
import org.springframework.web.servlet.ViewResolver; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 
import org.springframework.web.servlet.view.InternalResourceViewResolver; 
import org.springframework.web.servlet.view.JstlView; 

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "com.test.config") 
public class HelloConfig { 
    @Bean 
    public ViewResolver viewResolver() { 
     InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
     viewResolver.setViewClass(JstlView.class); 
     viewResolver.setPrefix("/WEB-INF/view/"); 
     viewResolver.setSuffix(".jsp"); 

     return viewResolver; 
    } 
} 

und Inhalt meiner HelloInitializer.java:

package com.test.config; 
import javax.servlet.ServletContext; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRegistration; 
import org.springframework.web.WebApplicationInitializer; 
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; 
import org.springframework.web.servlet.DispatcherServlet; 

public class HelloInitializer implements WebApplicationInitializer { 
    public void onStartup(ServletContext container) throws ServletException { 

     AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); 
     ctx.register(HelloConfig.class); 
     ctx.setServletContext(container); 

     ServletRegistration.Dynamic servlet = container.addServlet("dispatcher", new DispatcherServlet(ctx)); 

     servlet.setLoadOnStartup(1); 
     servlet.addMapping("/hello/*"); 
    } 
} 

und Inhalt meiner HelloController.java:

package com.test.config; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.ModelMap; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 

@Controller 
@RequestMapping("/") 
public class HelloController { 

    @RequestMapping(method = RequestMethod.GET) 
    public String sayHello(ModelMap model) { 
     model.addAttribute("greeting", "Hello World from Spring 4 MVC"); 
     return "welcome"; 
    } 

    @RequestMapping(value = "/helloagain", method = RequestMethod.GET) 
    public String sayHelloAgain(ModelMap model) { 
     model.addAttribute("greeting", "Hello World Again, from Spring 4 MVC"); 
     return "welcome"; 
    } 
} 

aber ich lief dieses Projekt auf dem Server und bekam diesen Fehler:

ich diesen Code verwendet haben, anstatt letzten HelloInitializer.java:

package com.test.config; 



import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; 

public class HelloInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return null; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class[] { HelloConfig.class }; 
    } 

    @Override 
    protected String[] getServletMappings() { 
     return new String[] { "/" }; 
    } 
} 

, aber ich habe diesen Fehler:

Wie kann ich diesen Fehler beheben?

Answer 1

Ihre Frontcontroller, bekannt als Dispatcherservlet ist nicht in der Lage, Ihre Config-Klasse zu finden. versuchen diese

@ComponentScan(basePackages = "com.test") 
public class HelloConfig { } 

oder

@ComponentScan(basePackages = "com.test.*") 
public class HelloConfig { } 

statt dessen

@ComponentScan(basePackages = "com.test.config") 
public class HelloConfig {} 

Answer 2

haben Sie Ihre Ordnerstruktur wie dies teilen:

Java Resources 
    src 
     com.test.config 
      HelloConfig.java 
      HelloController.java 
      HelloInitializer.java 
WebContent 
    META-INF 
     MANIFEST.MF 
    WEB-INF 
     lib 
     view 
      welcome.jsp 

ich nicht Ihre HelloConfig-servlet.xml innerhalb WEB_INF hier finden konnten. Wenn Sie das wirklich in WEB-INF haben, aber es hier irgendwie vermissen, würde ich Ihnen empfehlen, Ihre Buildpath-Konfiguration zu überprüfen. Meine Vermutung ist irgendwie WEB-INF ist nicht in der Build-Pfad registriert
