Springboot 依赖项：找到两个依赖项并忽略 Qualifier

Question

这是我的 class:

@Repository
@RequiredArgsConstructor
@Slf4j
public class ServeiTerritorialCatalegsClientRepositoryImpl implements ServeiTerritorialCatalegsClientRepository {

    @Qualifier("catalegsMarshaller") private final Marshaller marshaller;

    //...
}

我的 bean 定义是：

@Bean
public Marshaller oidMarshaller() throws JAXBException {
   //...
}

@Bean
public Marshaller catalegsMarshaller() throws JAXBException {
  //...
}

我收到这条消息：

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 3 of constructor in cat.catsalut.hes.mpi.hazelcast.loader.repository.ServeiTerritorialCatalegsClientRepositoryImpl required a single bean, but 2 were found:
    - oidMarshaller: defined by method 'oidMarshaller' in class path resource [cat/catsalut/hes/mpi/hazelcast/loader/configuration/ServeiTerritorialConfiguration.class]
    - catalegsMarshaller: defined by method 'catalegsMarshaller' in class path resource [cat/catsalut/hes/mpi/hazelcast/loader/configuration/ServeiTerritorialConfiguration.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

Answer 1

在 class ServeiTerritorialCatalegsClientRepositoryImpl 中似乎有一个构造函数，其第三个参数是 Marshaller 类型。因此，在构造函数中定义参数时，对参数类型 Marshaller 使用限定符属性，如下所示：

public ServeiTerritorialCatalegsClientRepositoryImpl(parameter1, paramter2, @Qualifier("catalegsMarshaller") Marshaller marshaller1)

Answer 2

Lombok 不会将注释从字段复制到构造函数参数或属性访问器。您现在需要自己提供构造函数。

Answer 3

您需要做两件事：

更新 lombok.config 并添加 -

lombok.copyableAnnotations += org.springframework.beans.factory.annotation.Qualifier
使用@Qualifier 并提供合适的唯一名称。例如：

@Repository
@RequiredArgsConstructor
@Slf4j
public class MyImplClass{
  @Qualifier("Myqualifier1") MyBean bean;
 
  Person getPerson()
}
