这是我的考试班.

 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(classes = AppConfig.class,loader = AnnotationConfigContextLoader.class)
 public class UserServiceImplIT {

@Autowired
private SampleService sampleService; 

@BeforeClass
public static void setUp() {
    System.out.println("-----> SETUP <-----");
}

@Test
public void testSampleService() {
    assertTrue(true);
}
  }      

例外(许多例外,主要：
 无法加载ApplicationContext,
 创建名为’defaultServletHandlerMapping’的bean时出错.
无法实例化[org.springframework.web.servlet.HandlerMapping]：工厂方法’defaultServletHandlerMapping’抛出异常;,
需要ServletContext来配置默认的servlet处理
)

AppConfig – 基本配置文件.

@Configuration
@ComponentScan("ru.moneymanager.web")
@EnableWebMvc
@EnableTransactionManagement
@PropertySource(value = {"classpath:application.properties"})
@Import({SecurityConfig.class,})
public class AppConfig {

@Bean
public SampleService getSampleService() {
    return new SampleServiceImpl();
}

@Bean
public InternalResourceViewResolver setupViewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/pages/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);

    return resolver;
}

@Autowired
private Environment environment;

@Bean
public LocalSessionfactorybean sessionFactory() {
    LocalSessionfactorybean sessionFactory = new LocalSessionfactorybean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan(new String[]{"ru.moneymanager.web"});
    sessionFactory.setHibernateProperties(hibernateProperties());
    return sessionFactory;
}

@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getrequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(environment.getrequiredProperty("jdbc.url"));
    dataSource.setUsername(environment.getrequiredProperty("jdbc.username"));
    dataSource.setPassword(environment.getrequiredProperty("jdbc.password"));
    return dataSource;
}

private Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect",environment.getrequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql",environment.getrequiredProperty("hibernate.show_sql"));
    properties.put("hibernate.format_sql",environment.getrequiredProperty("hibernate.format_sql"));
    properties.put("hibernate.hbm2ddl.auto",environment.getrequiredProperty("hibernate.hbm2ddl.auto"));
    return properties;
}

@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setSessionFactory(s);
    return txManager;
}

}

SecurityConfig

@Configuration
@ComponentScan("ru.moneymanager.web")
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
AuthenticationService authenticationService;
@Override
protected void configure(HttpSecurity http) throws Exception {
    CharacterEncodingFilter filter = new CharacterEncodingFilter();
    filter.setEncoding("UTF-8");
    filter.setForceEncoding(true);
    // отключена защита csrf на время тестов
    http.csrf().disable().addFilterBefore(filter,CsrfFilter.class);
    http.authorizeRequests().antMatchers("/account/**").hasRole("USER")
            .antMatchers("/user/**").hasRole("ADMIN")
            .and().formLogin();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(authenticationService);
}   
   }       

其他配置文件config
这个项目在git project
告诉我出了什么事？为什么错误？
