我有使用 Dao 类的 Service 类。我使用 javax 注入注解。
服务类：
public class TaxiServiceCar {
@Inject
private final CarDao carDao;
public TaxiServiceCar(CarDao carDao){
this.carDao = carDao;
}
public boolean insertCar(Car car) {
Connection connection = MySQLDAOFactory.getConnection();
boolean result = carDao.insertCar(connection,car);
ConnectionUtil.commit(connection);
ConnectionUtil.oneMethodToCloseThemAll(null,null,connection);
return result;
}
// Others methods
}
我有使用 mockito 的 ServiceTest 类
@ExtendWith(MockitoExtension.class)
class TaxiServiceCarTest {
@Mock
private CarDao carDao;
@InjectMocks
private TaxiServiceCar taxiServiceCar;
@Test
void insertCar() {
when(carDao.insertCar(any(Connection.class),any(Car.class))).thenReturn(true);
Car car = new Car();
assertTrue(taxiServiceCar.insertCar(car));
}
//others Test methods
}
当我运行测试时，我在 MySQLDAOFactory 类中得到 NullPointer 异常，我从连接池获取连接 我在哪里获得 NPE
public class MySQLDAOFactory extends DAOFactory {
private static final Logger LOGGER = LogManager.getLogger(MySQLDAOFactory.class);//Here
private static DataSource dataSource;
public static void dataSourceInit(){
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:comp/env");
dataSource = (DataSource) envContext.lookup("jdbc/UsersDB");
} catch (NamingException e) {
LOGGER.error(e);
}
}
public static Connection getConnection() {
if(dataSource==null){
dataSourceInit();
}
Connection connection = null;
try {
connection = dataSource.getConnection();//Here
} catch (SQLException e) {
LOGGER.error(e);
}
return connection;
}
@Override
public CarDao getCarDao() {
return new MySQLCarDao();
}
@Override
public UserDao getUserDao() {
return new MySQLUserDao();
}
@Override
public OrderDao getOrderDao() {
return new MySQLOrderDao();
}
@Override
public CarCategoryDao getCarCategoryDao() {
return new MySQLCarCategoryDao();
}
}
当我尝试在 MySQLDAOFactory 中获取 Logger 时，我也得到了 NPE
private static final Logger LOGGER = LogManager.getLogger(MySQLDAOFactory.class);
