尝试使用@Autowired 时没有类型的限定 bean

Question

这是项目的结构：

com
    ->services
        ->dal
            ->dao

这是类:

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{

}

测试：

@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>

也在尝试将其切换为：

<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

问题是spring没有意识到他找不到文件类路径：**/applicationContext.xml，我预计在那种情况下会出现找不到文件的异常。

将它更改为 file:../../../<explicit path> 一切正常。
