如何通過內置的JUnit測試自動連接服務

Question

如何僅通過使用彈簧注釋在測試類中自動裝配服務

當我嘗試以下錯誤時，在UserServiceImp類中使用@Service批注

2014-12-20 15:35:52錯誤TestContextManager：334-在允許TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@5af97850]准備測試實例[com.amsb.bariz.base.test]時捕獲了異常。 UserTest @ 4520ebad] org.springframework.beans.factory.BeanCreationException：創建名稱為'com.amsb.bariz.base.test.UserTest'的bean時出錯：自動連接依賴項的注入失敗； 嵌套的異常是org.springframework.beans.factory.BeanCreationException：無法自動連線字段：public com.amsb.bariz.base.service.UserService com.amsb.bariz.base.test.UserTest.userService; 嵌套的異常是org.springframework.beans.factory.NoSuchBeanDefinitionException：沒有找到類型為[com.amsb.bariz.base.service.UserService]的合格Bean作為依賴項：預計至少有1個Bean可以作為此依賴項的自動裝配候選。 依賴項注釋：{@ org.springframework.beans.factory.annotation.Autowired（required = true）}

我的服務等級是

@Service("userService")
public class UserServiceImp implements UserService {

    @Autowired
    private UserDao userDao;

    @Autowired
    private UserRoleDao userRoleDao;

    public void register(User user) {

        PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();

        user.setPassword(passwordEncoder.encode(user.getPassword()));
        Calendar calendar = Calendar.getInstance();
        java.util.Date now = calendar.getTime();

        Date dateNow = new Date(20070266);
        Timestamp dn = new Timestamp(now.getTime());
        user.setStatus("P");
        user.setCreated_on(dn);
        user.setEnabled(false);

        UserRole ur = new UserRole(user,"USER_ROLE");


        System.out.println("XDXDX ::" + user.toString());
        userDao.create(user);
        userRoleDao.create(ur);

    }

}

Answer 1

您是否正在嘗試將測試本身用作Spring配置的一部分？ 那是行不通的。 您需要做的是：-從測試本身中刪除@Configuration和@ComponentScan批注-創建一個簡單的TestConfiguration類：

@Configuration
@ComponentScan(basePackages={"com.amsb.bariz.base.service"})
@ImportResource("classpath:spring/spring-main.xml")
public class TestConfiguration{ }

並在測試中引用它：

@ContextConfiguration(classes = { TestConfiguration.class }, loader = AnnotationConfigContextLoader.class)
public class UserTest {

並且您應該能夠很好地注入服務。

希望能幫助到你。
