Question

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);
}
  }

异常（很多例外，主要： 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;
}

}

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中告诉我，有什么不对？为什么会出错？

Answer 1

您的测试需要ServletContext：添加@WebIntegrationTest

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

...或者在此处查看其他选项：https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

<强>更新在Spring Boot 1.4.x及更高版本@WebIntegrationTest不再是首选。 @SpringBootTest或@WebMvcTest

Answer 2

就我而言，在使用Junit5运行时，我必须执行以下操作

@SpringBootTest（classes = {abc.class}） @ExtendWith（SpringExtension.class

这里abc.class是要测试的类

Answer 3

能够使用下面的注释修复相同的问题。所以在这种情况下，Spring 只使用目标类 (Abc.class)，而不是整个应用程序上下文。

@SpringBootTest(properties = "spring.main.lazy-initialization=true",
classes = {Abc.class})

无法加载ApplicationContext（带注释）
