W oparciu o WebAppCinfig java:

@EnableWebMvc

@Configuration

@Import(value = SecurityConfig.class)

@ComponentScan(basePackages = {"com.examples"})

@ImportResource({ "classpath:spring-security-config.xml" })

public class WebAppConfig extends WebMvcConfigurerAdapter { public WebAppConfig() {

 super();

 } @Override

 public void addViewControllers(final ViewControllerRegistry registry) {

 super.addViewControllers(registry); registry.addViewController("/anonymous.html"); registry.addViewController("/login.html");

 registry.addViewController("/homepage.html");

 } @Bean

 public ViewResolver viewResolver() {

 final InternalResourceViewResolver bean = new InternalResourceViewResolver(); bean.setViewClass(JstlView.class);

 bean.setPrefix("/WEB-INF/views/");

 bean.setSuffix(".jsp"); return bean;

 }

}

Plik SecurityConfig.java dla bezpieczeństwa:

@Configuration

@ImportResource({ "classpath:spring-security-config.xml" })

public class SecurityConfig { public SecurityConfig() {

 super();

 }}

I wreszcie klasa WebAppConfig.java:

Teraz otrzymuję

org.springframework.beans.factory.NoSuchBeanDefinitionException: Żaden komponent bean o nazwie „springSecurityFilterChain” nie jest zdefiniowany

w podstawowym projekcie Spring Security Java, nad którym pracuję. Wszystko działa dobrze z konfiguracją adnotacji i jest doskonale przetestowane. Z jakiegoś powodu Spring generuje taki błąd podczas próby wykonania przykładu logowania w formularzu Spring Security.
Również na wiosnę-security-config.xml próbowano zmienić

& < http use-expressions = "true" & >

na

& < http auto-config = "true" & >

, ale nadal nie można rozwiązać żadnego komponentu bean o nazwie

„springSecurityFilterChain”

znalezionego wyjątku.
Jakakolwiek pomoc w tej sprawie byłaby bardzo mile widziana.
Podziękować,
