我正在使用Spring Boot和Spring Boot JPA编写组件。我有这样的设置:
界面:
public interface Something {
// method definitions
}
实现:
@Component
public class SomethingImpl implements Something {
// implementation
}
现在,我有一个运行
SpringJUnit4ClassRunner
的JUnit测试,我想以此测试我的SomethingImpl
。当我做
@Autowired
private Something _something;
它有效,但是
@Autowired
private SomethingImpl _something;
导致测试无法通过消息
NoSuchBeanDefinitionException
抛出No qualifying bean of type [com.example.SomethingImpl] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
但是在测试用例中,我想显式注入
SomethingImpl
,因为它是我要测试的类。我该如何实现? 最佳答案
如果您想要特殊的bean,则必须使用@Qualifier
批注:
@Autowired
@Qualifier("SomethingImpl")
private Something _something;
