Keine Zuordnung für HTTP-Anforderung mit URI mit java-basierte Konfiguration gefunden

Question

Während Frühling Lernen ich versuchte, Code-Beispiele von Spring in Aktion zu laufen, aber es gibt mir die unten genannten Fehler in tomcat Protokolle zeigt:

11-Aug-2016 12:15:57.561 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/RestTester-0.0.1-SNAPSHOT/] in DispatcherServlet with name 'dispatcher' 

Ich versuche, den Frühling nur mit Hilfe der Java-basierten Konfiguration zu konfigurieren. -Code für die gleiche ist nachfolgend aufgeführt:

TestProjectInitializer.java

package test.config; 

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

public class TestProjectInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     // TODO Auto-generated method stub 
     return new Class<?>[]{RootConfig.class}; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     // TODO Auto-generated method stub 
     return new Class<?>[]{WebConfig.class}; 
    } 

    @Override 
    protected String[] getServletMappings() { 
     // TODO Auto-generated method stub 
     return new String[]{"/"}; 
    } 
} 

WebConfig.java

package test.config; 

import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.web.servlet.ViewResolver; 
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; 
import org.springframework.web.servlet.view.InternalResourceViewResolver; 

@Configuration 
@EnableWebMvc 
@ComponentScan("test.webconf") 
public class WebConfig extends WebMvcConfigurerAdapter{ 

    @Bean 
    public ViewResolver getViewResolver() 
    { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/WEB-INF/views/"); 
     resolver.setSuffix(".html"); 
     resolver.setExposeContextBeansAsAttributes(true); 
     return resolver; 
    } 

    @Override 
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) 
    { 
     configurer.enable(); 
    } 
} 

RootConfig.java

package test.config; 

import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.ComponentScan.Filter; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.FilterType; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 

@Configuration 
@ComponentScan(basePackages={"test"}, excludeFilters={@Filter(type=FilterType.ANNOTATION,value=EnableWebMvc.class)}) 
public class RootConfig { 

} 

HomeController.java

package test.controllers; 

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

@Controller 
/*@RequestMapping("/")*/ 
public class HomeController 
{ 
    @RequestMapping(value="/",method=RequestMethod.GET) 
    public String home() 
    { 
     return "home"; 
    } 

}

Bitte helfen Sie mir zu verstehen, was ich falsch mache.

Answer 1

Der Name des Basispakets auf Webmvc war falsch und sollte test.controller sein.
