Führen Sie Test.class, aber ich kann nicht geladen werden ApplicationContext

Question

Ich möchte Test AnnManagerTest.java erstellen, aber einen Fehler nach der Ausführung erhalten: Fehler beim Laden von ApplicationContext.

Dies ist mein Code:

1.SpringConfiguration.java

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = {"com.*"}) 
@EnableTransactionManagement 
public class SpringConfiguration extends WebMvcConfigurerAdapter { 

@Bean(name = "multipartResolver") 
public StandardServletMultipartResolver resolver() { 
    return new StandardServletMultipartResolver(); 
} 

@Bean 
public ViewResolver viewResolver() { 
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 

    viewResolver.setViewClass(InternalResourceView.class); 
    viewResolver.setPrefix("/WEB-INF/"); 
    viewResolver.setSuffix(".jsp"); 

    return viewResolver; 
} 

@Override 
public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     registry.addResourceHandler("/resources/**").addResourceLocations("/resources/").setCachePeriod(31556926); 
} 

@Override 
public void addInterceptors(InterceptorRegistry registry) { 
    registry.addInterceptor(new LoginInterceptor()); 
} 

@Bean 
public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean(); 

    em.setDataSource(dataSource()); 
    em.setPersistenceUnitName("MyKMPersistenceUnit"); 
    em.setPackagesToScan(new String[]{"com.model"}); 
    em.setJpaDialect(new HibernateJpaDialect()); 
    em.setJpaPropertyMap(jpaProperties()); 
    em.setJpaVendorAdapter(jpaVendorAdapter()); 

em.setPersistenceXmlLocation("classpath:/persistenceXXX.xml"); 
    return em; 
} 


@Bean 
public JpaVendorAdapter jpaVendorAdapter() { 
    HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter(); 
    jpaVendorAdapter.setDatabase(Database.HSQL); 
    jpaVendorAdapter.setShowSql(true); 
    jpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.HSQLDialect"); 
    return jpaVendorAdapter; 
} 


@Bean 
public Map<String, Object> jpaProperties() { 
    Map<String, Object> props = new HashMap<>(); 
    props.put("hibernate.dialect", DerbyTenSevenDialect.class.getName()); 
    props.put("hibernate.hbm2ddl.auto", "none"); 
    props.put("hibernate.show_sql", "true"); 
    props.put("hibernate.format_sql", "true"); 
    props.put("hibernate.connection.charSet", "UTF-8"); 
    return props; 
} 


@Bean 
public DataSource dataSource() { 
    DataSource dataSource = new DataSource(); 
    dataSource.setDriverClassName("org.postgresql.Driver"); 
    dataSource.setUrl("jdbc:postgresql://localhost:5432/KM"); 
    dataSource.setUsername("username"); 
    dataSource.setPassword("passwd"); 
    dataSource.setInitialSize(10); 
    dataSource.setMaxActive(100); 
    return dataSource; 
} 


@Bean 
public PlatformTransactionManager transactionManager() throws Exception { 
    JpaTransactionManager jpaTransactionManager = new JpaTransactionManager(); 
    jpaTransactionManager.setEntityManagerFactory(entityManagerFactory().getObject()); 
    jpaTransactionManager.setDataSource(dataSource()); 
    jpaTransactionManager.setJpaDialect(new HibernateJpaDialect()); 
    return jpaTransactionManager; 
} 


@Bean 
public EntityManager entityManager(EntityManagerFactory entityManagerFactory) { 
    return entityManagerFactory.createEntityManager(); 
} 


@Bean 
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() { 
    return new PersistenceExceptionTranslationPostProcessor(); 
} 


@Bean 
public SpringContextUtil springContextUtil() { 
    return new SpringContextUtil(); 
} 

}

2.SpringContextUtil.java

public class SpringContextUtil implements ApplicationContextAware { 

    @Override 
    public void setApplicationContext(ApplicationContext applicationContext) { 
     SpringContextUtil.applicationContext = applicationContext; 
    } 


    public static ApplicationContext getApplicationContext() { 
     return applicationContext; 
    } 

    public static Object getBean(String name) throws BeansException { 
     return applicationContext.getBean(name); 
    } 
} 

3.AnnManagerTest.java

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = {SpringConfiguration.class}, loader = AnnotationConfigContextLoader.class) 
public class AnnManagerTest extends AbstractTransactionalJUnit4SpringContextTests { 

@Test 
public void testDoModify() throws Exception { 
    ApplicationContext ctx = SpringContextUtil.getApplicationContext(); 
    AnnouncementHeaderService service = (AnnouncementHeaderService) ctx.getBean("announcementHeaderService"); 
    AnnouncementHeader announcementHeader = new AnnouncementHeader(); 
    announcementHeader.setAnnID(40); 
    announcementHeader = service.findByOne(announcementHeader); 
} 
} 

Dies ist meine Ausnahme:

2016-07-27 23:15:03 WARN GenericApplicationContext:546 - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

Wer kann mir sagen, was? Vielen Dank!!

Answer 1

ich das Problem gefunden, die folgende ist meine Lösung: In Testpaketen, Verzeichnis: com/controller/System hat drei java

1. AnnManagerTest.java 

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = {JpaTestConfig.class,  SpringContextUtil.class}) 
public class AnnManagerTest { 

@Test 
public void testDoModify() throws Exception { 
    ApplicationContext ctx = SpringContextUtil.getApplicationContext(); 
    AnnouncementHeaderService service = (AnnouncementHeaderService) ctx.getBean("announcementHeaderService"); 
    List<AnnouncementHeader> list = service.findAll(); 
    assertNotNull(list); 
} 
} 

2.JpaTestConfig.java 
@Configuration 
@EnableTransactionManagement

    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean(); 
    em.setDataSource(dataSource());

    em.setPackagesToScan(new String[]{"com.model"}); 
    em.setJpaDialect(new HibernateJpaDialect()); 
    em.setJpaPropertyMap(jpaProperties()); 
    em.setJpaVendorAdapter(jpaVendorAdapter()); 
    return em; 
} 

@Bean

} 

3.SpringContextUtil.java
