Ошибка создания компонента с именем defaultServletHandlerMapping

Я преобразовал всю мою конфигурацию Spring Spring в Java-код, но я не могу запустить весь свой тест (с которым они работали раньше), потому что у меня есть уродливое исключение:

это мой тестовый class:

 @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes=ApplicationContextTest.class) public class AccountServiceTest { .. } 

и мой ApplicationContextTest :

 @Configuration @EnableTransactionManagement @PropertySource({ "classpath:databaseTest.properties" }) @ComponentScan(basePackages = { "org.example.springproject" }) public class ApplicationContextTest { @Autowired private Environment env; @Bean(name = "dataSource") public DataSource dataSource() { return new EmbeddedDatabaseBuilder() .setType(EmbeddedDatabaseType.HSQL) .addScript("classpath:sql/schema.sql") .addScript("classpath:sql/test-data.sql") .build(); } @Bean(name = "sessionFactory") public LocalSessionFactoryBean sessionFactory() { LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); sessionFactory.setDataSource(dataSource()); sessionFactory.setPackagesToScan(new String[] { "org.example.springproject.domains" }); sessionFactory.setHibernateProperties(hibernateProperties()); return sessionFactory; } @Bean(name = "transactionManager") public HibernateTransactionManager transactionManager() { HibernateTransactionManager txManager = new HibernateTransactionManager(); txManager.setSessionFactory(sessionFactory().getObject()); return txManager; } @SuppressWarnings("serial") private Properties hibernateProperties() { return new Properties() { { setProperty("hibernate.cache.provider_class", env.getProperty("hibernate.provider_class")); setProperty("hibernate.show_sql", env.getProperty("hibernate.show_sql")); setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl")); } }; } } к @Configuration @EnableTransactionManagement @PropertySource({ "classpath:databaseTest.properties" }) @ComponentScan(basePackages = { "org.example.springproject" }) public class ApplicationContextTest { @Autowired private Environment env; @Bean(name = "dataSource") public DataSource dataSource() { return new EmbeddedDatabaseBuilder() .setType(EmbeddedDatabaseType.HSQL) .addScript("classpath:sql/schema.sql") .addScript("classpath:sql/test-data.sql") .build(); } @Bean(name = "sessionFactory") public LocalSessionFactoryBean sessionFactory() { LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); sessionFactory.setDataSource(dataSource()); sessionFactory.setPackagesToScan(new String[] { "org.example.springproject.domains" }); sessionFactory.setHibernateProperties(hibernateProperties()); return sessionFactory; } @Bean(name = "transactionManager") public HibernateTransactionManager transactionManager() { HibernateTransactionManager txManager = new HibernateTransactionManager(); txManager.setSessionFactory(sessionFactory().getObject()); return txManager; } @SuppressWarnings("serial") private Properties hibernateProperties() { return new Properties() { { setProperty("hibernate.cache.provider_class", env.getProperty("hibernate.provider_class")); setProperty("hibernate.show_sql", env.getProperty("hibernate.show_sql")); setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl")); } }; } } к @Configuration @EnableTransactionManagement @PropertySource({ "classpath:databaseTest.properties" }) @ComponentScan(basePackages = { "org.example.springproject" }) public class ApplicationContextTest { @Autowired private Environment env; @Bean(name = "dataSource") public DataSource dataSource() { return new EmbeddedDatabaseBuilder() .setType(EmbeddedDatabaseType.HSQL) .addScript("classpath:sql/schema.sql") .addScript("classpath:sql/test-data.sql") .build(); } @Bean(name = "sessionFactory") public LocalSessionFactoryBean sessionFactory() { LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); sessionFactory.setDataSource(dataSource()); sessionFactory.setPackagesToScan(new String[] { "org.example.springproject.domains" }); sessionFactory.setHibernateProperties(hibernateProperties()); return sessionFactory; } @Bean(name = "transactionManager") public HibernateTransactionManager transactionManager() { HibernateTransactionManager txManager = new HibernateTransactionManager(); txManager.setSessionFactory(sessionFactory().getObject()); return txManager; } @SuppressWarnings("serial") private Properties hibernateProperties() { return new Properties() { { setProperty("hibernate.cache.provider_class", env.getProperty("hibernate.provider_class")); setProperty("hibernate.show_sql", env.getProperty("hibernate.show_sql")); setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl")); } }; } } 

Я попробовал put @WebAppConfiguration на моем тестовом classе, но это не сработало. Проект – проект Spring MVC, но теперь я тестирую только уровень сервиса, так почему мне нужно добавить эту аннотацию в мой class? Даже с этой аннотацией приходит еще одна ошибка. Итак, что здесь происходит?

Ваша конфигурация прекрасна, за исключением одного места

@ComponentScan (basePackages = {“org.example.springproject”})

Я бы предположил, что у вас есть другая @Configuration в вашем пакете, которую выбрал ваш @ComponentScan ( DelegatingWebMvcConfiguration, который появляется в вашем исключении, скорее всего, импортируется @EnableWebMvc где-то во внешней @Configuration ).

Возможным решением является использование фильтра при сканировании компонентов.

@ComponentScan (basePackages = {“org.example.springproject”}, excludeFilters = {@Filter (type = FilterType.ANNOTATION, value = Configuration.class)})

Добавьте @WebAppConfiguration и также замените class ApplicationContextTest .class с помощью AnnotationConfigWebContextLoader .class

например

  @WebAppConfiguration @ContextConfiguration(loader = AnnotationConfigWebContextLoader.class, classes = { ApplicationContextTest.class}) 

Класс AccountServiceTest должен вводить bean-компонент в SpingMVC или объявляться в конфиге, которая поддерживает SpringMVC. В проекте pom.xml добавьте зависимость javax.servlet-api к области проверки.

  javax.servlet javax.servlet-api test  

Я помню из недавнего проекта, в котором мы не могли использовать Spring jUnit Runner для веб-приложения. Нам пришлось удалить Sprint jUnit runner. Затем мы дополнили его загрузкой весной в базовом classе, полученном TestCase.
