JUnit测试：NoSuchBeanDefinitionException：没有类型的合格bean

Question

我收到以下异常：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.servlet.http.HttpServletRequest] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

这是我的JUnit：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class)
@Transactional
public class Prueba {

    private static final String FIRSTNAME = "TestFirstName";
    private static final String LASTNAME = "TestLastName";
    private static final String EMAIL = "[email protected]";
    private static final String PASSWORD = "TestPassword";
    private static final String PHONENUMBER = "00000000";
    private static final String ROLE = "USER";

    @PersistenceContext
    private EntityManager em;

    @Autowired
    private UserHibernateDao userDao; // THIS SEEMS TO BE THE ISSUE!
    private JdbcTemplate jdbcTemplate;
    private long user_id;

    @Before
    @Transactional
    public void setUp() {

        User u;
        for (int i = 0; i < 50; i++) {
            u = new User();
            u.setFirstName(i + FIRSTNAME + i);
            u.setLastName(i + LASTNAME + i);
            u.setEmail(i + EMAIL);
            u.setLocked(false);
            em.persist(u);
            if (i == 10) {
                this.user_id = u.getUserid();
            }

        }
    }

    @Rollback
    @Test
    public void testCreate() {
        final User user =  userDao.create(FIRSTNAME, LASTNAME, EMAIL, PASSWORD, PHONENUMBER, ROLE);
        assertNotNull(user);
    }
}

我在代码中指出的问题似乎是当我自动连接UserHibernateDao时。

这是我的TestConfig：

@ComponentScan({"src.main.java.ar.edu.itba.paw.persistence",   })
@Configuration
public class TestConfig {

    @Bean
    public DataSource dataSource() {
        final SimpleDriverDataSource ds = new SimpleDriverDataSource();
        ds.setDriverClass(JDBCDriver.class);
        ds.setUrl("jdbc:hsqldb:mem:paw");
        ds.setUsername("ha");
        ds.setPassword("");
        return ds;
    }

     @Bean
     public LocalContainerEntityManagerFactoryBean getEntityManagerFactory() {
         final LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
         factoryBean.setPackagesToScan("ar.edu.itba.paw.models");
         factoryBean.setDataSource(dataSource());
         final JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
         factoryBean.setJpaVendorAdapter(vendorAdapter);
         final Properties properties = new Properties();
         properties.setProperty("hibernate.hbm2ddl.auto", "update");
         properties.setProperty("hibernate.search.default.directory_provider", "filesystem");
         properties.setProperty("hibernate.search.default.indexBase", "lucene/indexes");
         properties.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
         properties.setProperty("hibernate.show_sql", "true");
         properties.setProperty("format_sql", "true");
         factoryBean.setJpaProperties(properties);
         return factoryBean;
       }



     @Bean
     public PlatformTransactionManager transactionManager(final EntityManagerFactory emf) {
          return new JpaTransactionManager(emf);
     }

     @Bean
        public PasswordEncoder passwordEncoder() {
            return new BCryptPasswordEncoder();
        }
}

这是我的包裹的外观：

关于如何解决它的任何想法？

我尝试更换我的@ComponentScan（{“ src.main.java.ar.edu.itba.paw.persistence”，}）

至@ComponentScan（{“ ar.edu.itba.paw.persistence”，}）

但是这也不起作用。

也是这是我的UserHibernateDao class。

您尝试@Autowired的类应该用@Service或@Component注释
