ClassCastException: класс by.AppInit не может быть приведен к классу javax.servlet.ServletContainerInitializer

Question

Помощь !! Все ответы, которые я нашел: изменить версию javax.servlet-api на 3.0.1 изменить на org.mortbay.jetty: servlet-api: 3.0.20100224 изменить область действия при условии, изменить версию весны на 5.1.6.RELEASE, openJDK 11 нет Работа. Запуск: mvn tomcat7: запустить Очистить и установить проект не было ошибок.

Настройка AppInit из документов Spring:

public class AppInit implements WebApplicationInitializer {

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

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

WebConf:

@Configuration
@EnableWebMvc
@ComponentScan
@EnableTransactionManagement
@PropertySource("classpath:database.properties")
@PropertySource("classpath:hibernate.properties")
public class WebConfig implements WebMvcConfigurer {

@Autowired
private Environment env;

@Autowired
private ApplicationContext applicationContext;

@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    registry.viewResolver(resolver);
}

@Bean
public SpringResourceTemplateResolver templateResolver() {
    SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
    templateResolver.setApplicationContext(applicationContext);
    templateResolver.setCacheable(true);
    templateResolver.setTemplateMode(TemplateMode.HTML);
    templateResolver.setPrefix("/WEB-INF/views/");
    templateResolver.setSuffix(".html");
    return templateResolver;

@Bean

    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver());
    templateEngine.setEnableSpringELCompiler(true);
    return templateEngine;
}

@Bean
public BasicDataSource dataSource() {
    BasicDataSource dataSource = new BasicDataSource();

    dataSource.setUrl(env.getProperty("connection.url"));
    dataSource.setUsername(env.getProperty("connection.username"));
    dataSource.setPassword(env.getProperty("connection.password"));
    dataSource.setDriverClassName(env.getProperty("connection.driver_class"));
    dataSource.setMaxTotal(Integer.parseInt(env.getProperty("connection.max_total")));

    return dataSource;
}

@Bean
public LocalSessionFactoryBean localSessionFactoryBean(DataSource dataSource) {
    LocalSessionFactoryBean localSessionFactoryBean
            = new LocalSessionFactoryBean();

    localSessionFactoryBean.setDataSource(dataSource);
    localSessionFactoryBean.setHibernateProperties(hibernateProperties());
    localSessionFactoryBean.setAnnotatedPackages("by/entity");
    localSessionFactoryBean.setPackagesToScan("by/entity");

    return localSessionFactoryBean;
}

private Properties hibernateProperties() {
    Properties properties = new Properties();

    properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
    properties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));

    return properties;
}

@Bean
public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
    HibernateTransactionManager transactionManager
            = new HibernateTransactionManager();

    transactionManager.setSessionFactory(sessionFactory);

    return transactionManager;
}}
