У меня есть веб-приложение Spring Boot, изначально созданное для внутреннего сервера Tomcat (работает). Затем я принял это приложение для запуска на сервере веб-логики. Мое приложение компилируется и развертывается на сервере без проблем, но когда оно не обслуживает страницы MVC. Каждый вызов выдает ошибку 404. Из приведенной ниже ошибки похоже, что сервлет spring dispatcher присутствует, но даже locale установлен неправильно. Я не могу понять, что здесь не так или отсутствует, но когда я создаю RestController вместо MVC, он работает, и отображается содержимое. Приложение основано на Sprint Boot 2.3.2

Application class:

 @SpringBootApplication
@ComponentScan({"ie.gov.agriculture.alf", "ie.gov.agriculture.sso"})
public class AlfApplication extends SpringBootServletInitializer implements WebApplicationInitializer {

    public AlfApplication() {
        super();
        setRegisterErrorPageFilter(false); // disable ErrorPageFilter causing bullshit error messages
    }

    @Override
    public void onStartup(ServletContext servletContext) {
        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
        appContext.register(AppConfig.class);
        appContext.register(WebMvcConfig.class);

        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher", new DispatcherServlet(appContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(AlfApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(AlfApplication.class, args);
    }
}
  

Класс AppConfig:

 @Configuration
@EnableCaching
public class AppConfig {

    @Bean
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("messages");
        return messageSource;
    }

    @Bean
    public LocalValidatorFactoryBean messageValidator() {
        LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
        validator.setValidationMessageSource(this.messageSource());
        return validator;
    }

    @Bean
    public ConversionServiceFactoryBean convertionService() {
        return new ConversionServiceFactoryBean();
    }

    @Bean
    public CacheManager cacheManager() {
        return new ConcurrentMapCacheManager("alfCache");
    }
}
  

наконец, класс WebMvcConfig:

 @Configuration
@ServletComponentScan
public class WebMvcConfig implements WebMvcConfigurer {

    @Bean
    public ViewResolver getViewResolver() {
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/WEB-INF/pages/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

    @Bean
    public CommonsMultipartResolver multipartResolver() {
        return new CommonsMultipartResolver();
    }

    @Bean
    public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter();
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        jsonConverter.setObjectMapper(objectMapper);
        return jsonConverter;
    }

    @Bean
    public CookieLocaleResolver cookieLocaleResolverExample() {
        CookieLocaleResolver localeResolver = new CookieLocaleResolver();
        localeResolver.setDefaultLocale(Locale.ENGLISH);
        localeResolver.setCookieName("alf-locale-cookie");
        localeResolver.setCookieMaxAge(3600);
        return localeResolver;
    }

    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver localeResolver = new SessionLocaleResolver();
        localeResolver.setDefaultLocale(Locale.UK);
        localeResolver.setDefaultTimeZone(TimeZone.getTimeZone("UTC"));
        return localeResolver;
    }

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

Ответ на эту проблему, как всегда, простой, компонент конфигурации сообщений должен выглядеть следующим образом, и все работает нормально, ключ — «classpath: » в setBasenema

 @Bean
public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    return messageSource;
}
