嘗試使用@Autowired時沒有類型的合格Bean

Question

這是項目的結構：

com
    ->services
        ->dal
            ->dao

這是類：

package com.services.dal.dao;
    @SuppressWarnings("unchecked")
    @Component
    public class PSDAO extends BaseDAO<ParkingSpots, ObjectId> implements IPSDAO{

    public PSDAO(Class<ParkingSpots> entityClass, MongoClient mongoClient, Morphia morphia,
            String datasource) {
        super(entityClass, mongoClient, morphia, datasource);
    }
}

接口：

package com.services.dal.dao;
public interface IPSDAO extends IBaseCRUD{

}

測試：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:**/applicationContext.xml")
public class PSDAOTest {

    @Autowired
    IPSDAO psDAO;
}

XML：

<bean class="com.services.dal.dao.PSDAO" id="PSDAO">
        <constructor-arg ref="morphia" index="0" />
        <constructor-arg ref="mongo" index="1" />
        <constructor-arg ref="mongoDb" index="2" />
</bean>

也在嘗試將其切換到：

<bean class="com.services.dal.dao.IPSDAO" id="PSDAO">
        <constructor-arg ref="morphia" index="0" />
        <constructor-arg ref="mongo" index="1" />
        <constructor-arg ref="mongoDb" index="2" />
</bean>

Answer 1

問題是spring無法識別他找不到文件classpath：** / applicationContext.xml，我希望在這種情況下會出現文件未找到異常。

通過將其更改為file:../../../<explicit path>一切正常。
