springboot autowiring@repository在@configuration中不起作用

Question

我有一个简单的Spring Boot应用程序，其中有一个jpa存储库对象，我希望它在@configuration类中自动生成，如下所示。

@Configuration
public class Appconfig {

    @Bean
    @Autowired
    public  PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer(OctopusPropertiesRepository repo) {
        PropertySourcesPlaceholderConfigurer property = new PropertySourcesPlaceholderConfigurer();
        Map<String,Object> props = new ConcurrentHashMap<>();
        List<OctopusProperties> loadedSettings = repo.findAll();
        loadedSettings.forEach(entry -> props.put(entry.getKey(), entry.getValue()));
        MutablePropertySources mutablePropertySources = new MutablePropertySources();
        mutablePropertySources.addFirst(new MapPropertySource("custom", props));
        property.setPropertySources(mutablePropertySources);
        return property;
    }
}

下面是@repository类

@Repository
public interface OctopusPropertiesRepository extends JpaRepository<OctopusProperties, Long> {
}

我有以下例外。

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.example.app.OctopusPropertiesRepository]

Answer 1

使用@PostConstruct。

@Autowired PropertySourcesPlaceholderConfigurer property;


@Autowired OctopusPropertiesRepository repo;


   @PostConstruct
    public  void onInit() {

        Map<String,Object> props = new ConcurrentHashMap<>();
        List<OctopusProperties> loadedSettings = repo.findAll();
        loadedSettings.forEach(entry -> props.put(entry.getKey(), entry.getValue()));
        MutablePropertySources mutablePropertySources = new MutablePropertySources();
        mutablePropertySources.addFirst(new MapPropertySource("custom", props));
        property.setPropertySources(mutablePropertySources);

    }
