我对使用 junit 4.10 和 mybatis 的 spring 3 测试有疑问。我无法在测试类中自动装配服务。

这是我得到的例外

我试图在 springBean 文件中手动注册 bean，但它得到一个空值。

我的模特班

@Component
public class MailReceiverAccountBean implements MailReceiverAccount {

    private String username;
    private String password;
//    private String email;
    private String serverAddress;
    private Integer serverPort;
    private MailProtocol mailProtocol;
//    private String name;
    private Boolean encrypted;
    private MailEncryptionType encryptionType;
    private String accountName;

omitted getter and setter ....

映射器类

@Repository
public interface MailReceiverAccountMapper {

    @Insert("INSERT INTO email_account(username, password, server_address, server_port, mail_protocol, account_name, encrypted, encryption_type)"
            + " VALUES(#{username}, #{password}, #{serverAddress}, #{serverPort}, #{mailProtocol, javaType=MailProtocol.class, jdbcType=JdbcType.VARCHAR, typeHandler=MailProtocolEnumHandler.class},"
            + " #{accountName}, #{encrypted}, #{encryptionType, javaType=MailProtocol.class, jdbcType=JdbcType.VARCHAR, typeHandler=MailEncryptionTypeEnumHandler.class})")
//    @Options(useGeneratedKeys = true, keyProperty = "id")
    public void insertEmailAccount(MailReceiverAccountBean mailReceiverAccountBean);

.........

服务等级

@Service("mailReceiverAccountService")
@Transactional(propagation = Propagation.SUPPORTS, readOnly = true)
public class MailReceiverAccountService implements DaoService<MailReceiverAccountBean>{

    @Autowired
    private SqlSession sqlSession;

    @Override
    public void save(MailReceiverAccountBean entity) {
        MailReceiverAccountMapper mailReceiverAccountMapper = sqlSession.getMapper(MailReceiverAccountMapper.class);
        mailReceiverAccountMapper.insertEmailAccount(entity);
    }
       ............

测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:testApplicationContext.xml")
public class MailReceiverAccountServiceTest {

    @Autowired
    private MailReceiverAccountService mailReceiverAccountService;


    /**
     * Test of save method, of class EmailAccountService.
     */
    @Test
    public void testSave() {
        System.out.println("save");
        MailReceiverAccountBean ea = this.getFilledEntity();
        mailReceiverAccountService.save(ea);

        Assert.assertTrue(ea.getId() != 0);

        MailReceiverAccountBean created = mailReceiverAccountService.findById(ea.getId());
        Assert.assertNotNull(created);
        Assert.assertEquals(ea, created);        
    }

怎么了？我失去了一些配置吗？提前致谢

解决了......问题是我试图在没有接口的情况下自动装配一个具体的bean

谢谢大家的回复:-)

将自动装配的代码从

@Autowired
private MailReceiverAccountService mailReceiverAccountService;

到

@Autowired
private DaoService mailReceiverAccountService;

如果您有多个 DaoService 实现类，请使用 @Qualifier 和 @Autowired 来区分它们。

在上下文 xml 中，您没有提供用于扫描带注释组件的基本包。因此，您的服务类不会被扫描和自动装配。请将此条目添加到上下文中

<context:annotation-config />
<context:component-scan base-package="basepackage" />
