스프링 4 HTTP 상태 404

Question

저는 스프링 4로 작업하기 시작했습니다. 자바 구성으로 스프링 4 MVC 프로젝트를 설정하고 싶습니다. IntelliJ Idea 13.1.6을 사용합니다. 먼저 Spring MVC 3.2 템플릿으로부터 새로운 Spring 4 MVC 프로젝트를 생성한다. 그런 다음 Java Spring 구성 파일을 추가하지만 응용 프로그램을 실행하면 홈 컨트롤러 대신 hello 템플릿 컨트롤러에서 "Hello world"라는 프로그램이 표시됩니다. 여기 내 프로젝트 파일입니다

그리고 :

HelloController :

package com.spitter.mvc; 

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 printWelcome(ModelMap model) { 
     model.addAttribute("message", "Hello world!"); 
     return "hello"; 
    } 
} 

RootConfig :

package spittr.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={"spitter"}, 
     excludeFilters={ 
       @Filter(type=FilterType.ANNOTATION, value=EnableWebMvc.class) 
     }) 
public class RootConfig { 
} 

SpittrWebAppInitializer :

package spittr.config; 
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; 
public class SpittrWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 
    @Override 
    protected String[] getServletMappings() { 
     return new String[] { "/" }; 
    } 
    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class<?>[] { RootConfig.class }; 
    } 
    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class<?>[] { WebConfig.class }; 
    } 
} 

HomeController :

package spittr.web; 
import static org.springframework.web.bind.annotation.RequestMethod.*; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 

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

왜이 코드는 홈 컨트롤러를 실행하지 만 안녕하세요 컨트롤러는 필자가 어떻게 고칠 수 있습니까?

나는 Spitter.iml 파일에 문제가 있다고 생각하는데, 스프링은 Java 클래스 구성 대신 web.xml 구성 만 볼 수 있습니다.

Answer 1

내가 보는 주된 문제는 구성과 몇 가지 작은 세부 사항입니다. 예에서 프로젝트를 구성하는 두 가지 방법 (Java 및 XML)을 사용하고 있습니다. Java 기반 구성을 사용하기를 선호하지만 충돌을 일으키지 않고 결합 할 수는 있습니다.

예를 들어 기본 패키지가있는 mvc-dispatcher-servlet.xml에 HelloController가 표시되어 있기 때문에 HelloController를 실행합니다.

<context:component-scan base-package="com.spitter.mvc"/> 

그리고 SpittrWebAppInitializer가 web.xml로 바뀝니다. 올바른 패키지를 지정하려면 XML 파일을 삭제하고 RootConfig를 수정해야합니다.

@ComponentScan(basePackages={"spittr"} 

이렇게 WebConfig도 비슷합니다.

@Configuration 
@EnableWebMvc 
@ComponentScan("spittr.web") 
public class WebConfig extends WebMvcConfigurerAdapter { 

    // Configure a JSP view resolver 
    @Bean 
    public ViewResolver viewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setViewClass(JstlView.class); 
     resolver.setPrefix("/WEB-INF/pages/"); 
     resolver.setSuffix(".jsp"); 
     return resolver; 
    } 

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

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     // TODO Auto-generated method stub 
     super.addResourceHandlers(registry); 
    } 
} 

그리고 당신은 당신이 오류가있을 것이다 @ComponentScan하는 패키지 com.spitter.mvc을 WebConfig에 추가하는 경우에만 예를 들어, 여러분의 컨트롤러에 고유 한 경로를 가질 수 있습니다.
