自动装配不适用于Maven依赖项的类

标签： spring-boot autowired

我正在尝试使用一些我的基于Spring的项目所需的代码创建一个共同共享的项目。我想避免代码重复，而是创建一个新项目，将代码放在此处，将其构建为JAR并将其上传到Sonatype Nexus。然后，我将该JAR作为依赖项包含在我的其他项目中。

但是，当我从依赖关系中使用这些类时，自动装配突然不再起作用了，我也不明白为什么，因为它是完全相同的代码（仅在另一个软件包中）。

在这种情况下，我有一个$ ./bin/verticalfind dat/vertword.txt found DOG at indexes 12, 17, 22 $ ./bin/verticalfind dat/vertword.txt RIEP found RIEP at indexes 5, 10, 15, 20 $ ./bin/verticalfind dat/vertword.txt MOP 'MOP' not found. 类，看起来像这样：

BaseService

mapper是Orika的一个类，可以通过spring-boot-starter来获得，我在公共项目和单个项目中都提供了它，

@Transactional
public abstract class BaseService {

    @Autowired
    protected MapperFacade mapper;

}

现在，我有一个如下服务类：

<dependency>
    <groupId>net.rakugakibox.spring.boot</groupId>
    <artifactId>orika-spring-boot-starter</artifactId>
    <version>1.8.0</version>
</dependency>

当@Service @Scope(proxyMode = ScopedProxyMode.TARGET_CLASS) public class AppointmentOptionService extends BaseService { ... } 类是我个人项目中的类时，一切正常，应用程序照常启动。但是，当我使用普通项目中的一个（仅更改导入）时，在启动时会遇到此异常：

BaseService

我尝试使用org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'scopedTarget.appointmentOptionService': Unsatisfied dependency expressed through field 'mapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'ma.glasnost.orika.MapperFacade' available: expected at least 1 bean which qualifies as autowire candidate.

我不明白为什么在代码完全相同的情况下，Spring无法在此基类中找到匹配的依赖项以进行自动装配。
