Question

我有这个类，我想访问ILibraryRepository的自动对象。我使用新的AddLibraryProcessor（）创建了这个类的对象。所以我使用了@Configurable但输出显示为null。

@Configurable(autowire = Autowire.BY_TYPE)
public class AddLibraryProcessor implements ICommandProcessor<AddLibrary> {

    @Autowired
    ILibraryRepository repository;

    @Override
    public IWebApiResponse Process(AddLibrary command) throws DomainProcessException{
        System.out.println(repository);
        return null;
    }
}

我的pom.xml看起来像：

Answer 1

默认情况下，@Configurable不会启用@EnableSpringConfigured对非托管弹簧的注入。您必须使用例如将@Configuration添加到任何8.8.1 Using AspectJ to dependency inject domain objects with Spring带注释的bean。

在阅读{{3}}时，您会注意到进一步的要求：

要使其工作，带注释的类型必须与AspectJ weaver [..]或加载时编织一起编织。

即使在@Configurable类之后，autowired对象也显示为null
