java使用来自另一个模块的Bean

Question

我正在创建一个批处理应用程序，将来自web服务的一些数据放到数据库中。 为此，我需要转换web服务在可利用类上接收的DTO。这可以使用其他模块中定义的映射器实现

当我尝试@Autowired映射器时，我遇到了一个例外，我不知道如何才能昏过去

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.execution.batch.processor.UtilisateurProcessor com.execution.batch.jobConfiguration.JobConfigurationAbstract.utilisateurProcessor; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'utilisateurProcessor': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.execution.server.common.mapper.UtilisateurMapper com.execution.batch.processor.UtilisateurProcessor.utilisateurMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.execution.server.common.mapper.UtilisateurMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

地图绘制人员在他们的模块中工作正常。我可以@Autowierdd他们，并使用它没有问题。如果我不@Autowierd映射程序，我的批处理工作正常

有人有主意吗

谢谢

编辑

我的配置在我的作业配置类中：

@Configuration
@EnableBatchProcessing
@ComponentScan(basePackages = {"com.execution.batch"})

我试着写：@ComponentScan(basePackages = {"com.execution.batch", "com.execution.serve"})

但如果我这样做，我会向工作bean的注入报告错误：

就像我说的，单独的模块可以很好地工作

• 当我扫描服务器和批处理模块时，批处理的扫描不起作用
• 当我只扫描批处理模块时，服务器模块不工作，因为我认为不是扫描

我猜你忘了用你想要的类的适当包设置“扫描器”

你的bean是utilisateurProcessor，fqn是com.execution.batch.processor.UtilisateurProcessor。它是配置为@组件还是在XML中

请粘贴spring的配置，以查看是否已将com.execution.server.common.mapper添加到spring的扫描仪
