我在部署代码时遇到以下异常
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [com.belk.api.adapter.contract.Adapter] is defined: expected single matching bean but found 2: [endeca, solar]

我有 3 个不同的项目，一个是 Common，第二个是 Adapter，第三个是 Service。 Adapter依赖Common，Service依赖Adapter。这三个都是maven项目。 现在在我的 Common 项目中，我有一个名为 CommonAdapter.java 的接口(interface)
public interface CommonAdapter {
List service() ;
}
我在同一个项目中有一个名为 AdapterFactory.java 的类(即 Common)
@Component
public class AdapterFactory {
@Autowired
Adapter adapter;
public Adapter getAdapter(String adapterName){
return adapter;
}
}
<context:component-scan base-package="com.test.api" />
<bean
class="org.springframework.beans.factory.config.ServiceLocatorFactoryBean"
id="adapterFactory">
<property name="serviceLocatorInterface" value="com.test.api.adapter.manager.AdapterFactory">
</property>
</bean>
现在在我的适配器项目中，我有 CommonAdapter.java 的实现类 一个是 EndecaAdapetr.java，另一个是 SolarAdapter.java
@Component("endeca")
public class EndecaAdapter implements Adapter {
List service() {
// My bussiness logic
}
}
@Component("solar")
public class SolarAdapter implements Adapter {
List service() {
// My bussiness logic
}
}
现在在我的Service项目中，想根据输入调用上面两个类的service方法。
public class ProductSearchServiceImpl {
@Autowired
private AdapterFactory adapterFactory;
public Search searchProducts(){
Adapter endecaAdapter = this.adapterFactory
.getAdapter("endeca ");
}
}
