Spring Boot应用程序不提供Web内容

Question

我有Spring Boot Web应用程序，最初是为内部Tomcat服务器构建的（有效）。然后我采用了该应用程序在Web Logic服务器上运行。我的应用程序编译并部署到服务器没有问题，但当它不服务MVC页面时。每次调用都会抛出404错误。从下面的错误看，它看起来像Spring调度程序servlet存在，但甚至区域设置都没有正确设置。我无法弄清楚这里有什么问题或缺失，但当我创建RestController而不是MVC时，它可以工作并显示内容。应用程序基于Sprint Boot 2.3.2

<代码>

应用类：

@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("/");

        ContextLoaderListener contextLoaderListener = new ContextLoaderListener(appContext);
        servletContext.addListener(contextLoaderListener);

        // Filter.
        FilterRegistration.Dynamic filterReg = servletContext.addFilter("encodingFilter", CharacterEncodingFilter.class);
        filterReg.setInitParameter("encoding", "UTF-8");
        filterReg.setInitParameter("forceEncoding", "true");
        filterReg.addMappingForUrlPatterns(null, true, "/*");
    }

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

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

AppConfig类：

@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");
    }
}

最后WebMvcConfig类：

@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();
    }
}

这个问题的答案通常是一个简单的技巧，消息配置bean应该是这样的，并且一切都很好，关键是setBasenema中的“classpath:”

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