这是我上课的考试。

@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);
    }
}

异常（许多异常，main： Failed to load ApplicationContext，

Error creating bean with name 'defaultServletHandlerMapping'。

Failed to instantiate [org.springframework.web.servlet.HandlerMapping]:

Factory method 'defaultServletHandlerMapping' threw exception;，

A ServletContext is required to configure default servlet handling ）

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;
    }
}

安全配置

@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 在git project中配置

该项目， 告诉我，怎么了？为什么会出错？

回答：

您的测试需要一个ServletContext：add @WebIntegrationTest

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

…或在此处查找其他选项：https :

//docs.spring.io/spring-boot/docs/current/reference/html/boot-features-

testing.html

@WebIntegrationTest不再是首选。@SpringBootTest要么@WebMvcTest
