Java 기반 구성을 사용하는이 Spring 애플리케이션이 제대로 작동하지 않는 이유

필자는 최근 Spring 프레임 워크를 사용하여 XML 설정 파일없이 Java 코드 만 개발하는 목적으로 프로젝트를 시작했습니다.

현재 현재 프로젝트에 다음 파일을 추가합니다.

WebAppConfig.java

@EnableWebMvc
@ComponentScan(value="org.webapp")
@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(31556926);
        registry.addResourceHandler("/css/**").addResourceLocations("/fonts/").setCachePeriod(31556926);
        registry.addResourceHandler("/img/**").addResourceLocations("/image/").setCachePeriod(31556926);
        registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(31556926);
    }

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

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/jsp/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

}

SecurityConfig.java

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("kleber").password("123").roles("USER");
    }

}

SecurityWebApplicationInitializer.java

@Order(value=2)
public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

    public SecurityWebApplicationInitializer() {
        super(SecurityConfig.class);
    }
}

이 상태에서 (Eclipse에서) 애플리케이션을 실행하면 브라우저는 Spring Security의 기본 로그인 양식을 표시하고이 양식을 제출하면 오류 404가 표시됩니다. localhost : 8080 / spring / index URL을 직접 입력하면 로그인 양식으로 표시 될 페이지에 액세스 할 수 있습니다.

이 클래스를 추가하면 :

WebAppInitializer.java

@Order(value=1)
public class WebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext container) {
      // Create the 'root' Spring application context
      AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
      rootContext.register(WebAppConfig.class);

      // Manage the lifecycle of the root application context
      container.addListener(new ContextLoaderListener(rootContext));

      // Create the dispatcher servlet's Spring application context
      AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
      dispatcherContext.register(DispatcherConfig.class);

      // Register and map the dispatcher servlet
      ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
      dispatcher.setLoadOnStartup(1);
      dispatcher.addMapping("/");
    }

}

공식 문서의 지침에 따라이 링크에서 web.xml로 대체하십시오.

http://docs.spring.io/spring/docs/3.1.x/javadoc-api/org/springframework/web/WebApplicationInitializer.html

로그인 페이지에 액세스 할 수도 없습니다. 클래스 SecurityConfig에 메소드를 추가하면 똑같은 일이 발생합니다.

protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/css/**", "/fonts/**", "/image/**", "/js/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("spring/index").permitAll()
                .failureUrl("spring/erro_login").permitAll()
                .defaultSuccessUrl("spring/home")
                .and()
            .logout()
                .logoutSuccessUrl("spring/logout")
                .permitAll();
    }

누군가 내가 뭘 놓친 걸 볼 수 있니?

추신.:

내 컨트롤러는 다음과 같습니다.

@Controller
@RequestMapping(value="spring")
public class SpringController {

    @RequestMapping(value="index")
    public ModelAndView index() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("index");
        return mav;
    }

    @RequestMapping(value="home")
    public ModelAndView home() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("home");
        return mav;
    }

    @RequestMapping(value="erro_login")
    public ModelAndView erro_login() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("erro_login");
        return mav;
    }

    @RequestMapping(value="erro_nao_autorizado")
    public ModelAndView erro_nao_autorizado() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("erro_nao_autorizado");
        return mav;
    }

    @RequestMapping(value="logout")
    public ModelAndView logout() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("index");
        return mav;
    }
}

최신 정보

이 오류는 Eclipse의 콘솔에 표시됩니다.

이 주제에 대한 답을 얻은 후 SecurityWebApplicationInitializer 또는 WebAppInitializer에서 ContextListeners의 충돌하는 등록 중 하나를 제거하려고합니다. 두 경우 모두이 오류가 발생합니다.

해결법

==============================
1.
```
java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!
```
WebAppInitializer에서 ContextLoaderListener를 등록하려고합니다.

AbstractSecurityWebApplicationInitializer를 Class []를 수락하는 수퍼 생성자와 함께 사용하기 때문에

또한 ContextLoaderListener를 등록합니다. javadoc 클래스를 주목하십시오.

오류로 인해 ServletContext에 ApplicationContext를 만들고 추가하려고하기 때문에 두 개의 ContextLoaderListener 인스턴스를 가질 수 없습니다.
==============================
2.나는 문제가 이것이라고 생각한다.

나는 문제가 이것이라고 생각한다.
```
.loginPage("spring/index").permitAll()
```
다음과 같아야합니다.
```
.loginPage("/spring/index").permitAll() //note the '/' at the beginning of the uri
```
==============================
3.어쩌면 web.xml과 java 기반 구성 클래스가 서로 겹치는 부분이있을 수 있습니다. 그것은 내가 당신과 같은 오류를 만났을 때의 근본 원인입니다. 그리고 내 솔루션은 web.xml에서 복제 된 구성을 주석 처리하는 것입니다.

4.나는 수업을했다.

나는 수업을했다.

내 코드 어딘가에. 그것은 사용되지 않았다. 봄 부팅은 분명히 그것을 찾기 위해 반사를 사용합니다. 파일을 삭제하고 문제가 사라졌습니다.
