JUnit测试 spring 注入问题报错

N_A_S_A 2018-03-30 03:08:09

Junit 代码

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "classpath*:/config/srping/core-root-context.xml", "classpath*:/config/srping/orm-context.xml" })

public class moitorTest {

	private MoitorServiceI moitorService;

	public MoitorServiceI getMoitorService() {

		return moitorService;

	}

	@Autowired

	//@Resource(name="moitorService")  

	public void setMoitorService(MoitorServiceI moitorService) {

		this.moitorService = moitorService;

	}

	@Test

	public void test1() {

	}



}

接口与实现类

@Service("moitorService")

public class MoitorServiceImpl implements MoitorServiceI {



	private ParkingMoitorLogMapper parkingMoitorLogMapper;



	@Override

	public List<ParkingMoitorLog> getMoitorLogByParkingCodeAndStartTime(String parkingCode, String startTime) {



		//return null;

		return parkingMoitorLogMapper.getMoitorLogByParkingCodeAndStartTime(parkingCode, startTime);

	}

}

public interface MoitorServiceI {

	/**

	 * Description: 获取错误日志信息<br>

	 * 

	 * @author <br>

	 * @taskId <br>

	 * @param ParkingCode

	 *            <br>

	 * @param StartTime

	 *            <br>

	 * @return <br>

	 */

	List<ParkingMoitorLog> getMoitorLogByParkingCodeAndStartTime(String parkingCode, String startTime);

}

spring 配置中扫描路径

    <!-- service -->

    <context:component-scan base-package="com.huibo.parking.moitor.service" />

启动之后报错无法实现注入，找不到接口对应的实现类

我感觉应该没有啥问题，看不出所以然，特此求助！

百度了有人说接口与实现类同目录我也是同目录下

引用 3 楼 Appleyk 的回复:

你的是同一个目录下，没看到，我去直接注入试试， @Autowired private MoitorServiceI moitorService 不行的话，检查下资源文件是不是关联上了

1.您说的同一个包下，接口与Impl类都是在同一个 "com.huibo.parking.moitor.service" 包下的 2.直接注在类上面报错同样我试过了 3.XML上面文应该没有问题吧，Junit加载上下文就SPRING的配置就可单测SERVICE层的。我看过了错误信息，我理解为是扫描包路径下文件，找不到接口对应的实现类才导致注入service异常的。所以我目前感觉是扫描的问题，不知道对不对。还请大神继续帮忙看看

<context:component-scan base-package="com.huibo.parking.moitor.serviceImpl" /> service和serviceImpl没有放在同一个包下，导致spring扫描的时候没有扫描Impl包，检查下
