春ブーツは、私が質問に会ったDAO

Question

を@Autowiredことはできませんが、私はそれはこれらが私の設定、DAOおよびサービスです

を失敗しています府、プロジェクトを起動しようと、誰もがなぜ私に言うことができるである、THXたくさん

これはDataBaseConfigurationです：

@Configuration 
@EnableTransactionManagement 
public class DataBaseConfiguration implements EnvironmentAware { 

    private RelaxedPropertyResolver propertyResolver; 

    private static Logger log = LoggerFactory.getLogger(DataBaseConfiguration.class); 

    @Override 
    public void setEnvironment(Environment env) { 
     this.propertyResolver = new RelaxedPropertyResolver(env, "dataSource."); 
    } 

    @Bean(destroyMethod = "close") 
    public DataSource dataSource() { 
     log.debug("Configuring DataSource"); 

     DruidDataSource druidDataSource = new DruidDataSource(); 
     druidDataSource.setUrl(propertyResolver.getProperty("url")); 
     druidDataSource.setDriverClassName(propertyResolver.getProperty("driverClassName")); 
     druidDataSource.setUsername(propertyResolver.getProperty("username")); 
     druidDataSource.setPassword(propertyResolver.getProperty("password")); 

     return druidDataSource; 
    } 
} 

これはMybatisConfigurationです：

@Configuration 
    @ConditionalOnClass({ EnableTransactionManagement.class, EntityManager.class}) 
    @AutoConfigureAfter({ DataBaseConfiguration.class }) 
    @MapperScan("com.future.api.**.dao") 
    public class MybatisConfiguration implements EnvironmentAware { 

     private static Log logger = LogFactory.getLog(MybatisConfiguration.class); 

     private RelaxedPropertyResolver propertyResolver; 

     @Autowired 
     private DataSource dataSource; 

     @Override 
     public void setEnvironment(Environment env) { 
      this.propertyResolver = new RelaxedPropertyResolver(env, "mybatis."); 
     } 

     @Bean 
     @ConditionalOnMissingBean 
     public SqlSessionFactory sqlSessionFactory() { 
      try { 
       SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean(); 
       sessionFactory.setDataSource(dataSource); 
       sessionFactory.setTypeAliasesPackage(propertyResolver 
         .getProperty("typeAliasesPackage")); 
       sessionFactory 
         .setMapperLocations(new PathMatchingResourcePatternResolver() 
           .getResources(propertyResolver 
             .getProperty("mapperLocations"))); 
       sessionFactory 
         .setConfigLocation(new DefaultResourceLoader() 
           .getResource(propertyResolver 
             .getProperty("configLocation"))); 
       return sessionFactory.getObject(); 
      } catch (Exception e) { 
       logger.warn("Could not configure mybatis session factory"); 
       return null; 
      } 
     } 

     @Bean 
     @ConditionalOnMissingBean 
     public DataSourceTransactionManager transactionManager() { 
      return new DataSourceTransactionManager(dataSource); 
     } 
    } 

T彼のDAO

public interface UserMapper extends BaseDao<User,UserCriteria ,String> { 
     @SelectProvider(type=UserSqlProvider.class, method="countByExample") 
     int countByExample(UserCriteria example); 

     @DeleteProvider(type=UserSqlProvider.class, method="deleteByExample") 
     int deleteByExample(UserCriteria example); 

     @Delete({ 
      "delete from t_user", 
      "where id = #{id,jdbcType=VARCHAR}" 
     }) 
     int deleteByPrimaryKey(String id); 

     @Insert({ 
      "insert into t_user (id, username, ", 
      "password, created_by, ", 
      "created_date, last_modified_by, ", 
      "last_modified_date)", 
      "values (#{id,jdbcType=VARCHAR}, #{username,jdbcType=VARCHAR}, ", 
      "#{password,jdbcType=VARCHAR}, #{createdBy,jdbcType=VARCHAR}, ", 
      "#{createdDate,jdbcType=DATE}, #{lastModifiedBy,jdbcType=VARCHAR}, ", 
      "#{lastModifiedDate,jdbcType=DATE})" 
     }) 
     int insert(User record); 
    } 

これはサービス

@Service 
@Transactional 
public class UserServiceImp extends BaseServiceImpl<User,UserCriteria> implements UserService { 

    @Autowired 
    private UserMapper userDao; 

    @Override 
    protected BaseDao<User, UserCriteria, String> getDao() { 
     return userDao; 
    } 
}

です私はあなたの問題は、この注釈かもしれ信じる：

@MapperScan("com.future.api.**.dao") 

私は持っていません前に見た（コードでもドキュメンテーションでも） ）ワイルドカードを使用することが可能であることを示します。正確なパッケージ名を使用してみてください。

私はそれがサブパッケージもスキャンしていると思うので、パッケージ構造を変更して、すべてのDAOを単一パッケージのツリーに収めたいかもしれません。
