我正在使用Spring Boot 2.0.5.RELEASE,Java 8开发一个多模块项目。它由模型,DAO和各种微服务组成。 DAO bean的使用由@Import批注提供,如下所示:
微服务:
@SpringBootApplication
@EnableBatchProcessing
@EnableDao
public class Application {
public static ConfigurableApplicationContext CONTEXT;
public static void main(String[] args) {
CONTEXT = SpringApplication.run(Application.class, args);
}
}
DAO:
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Import(DaoConfiguration.class)
public @interface EnableDao {
/* empty */
}
@Configuration
@EntityScan("blah.blah.blah.dao")
@EnableJpaRepositories("blah.blah.blah.dao.repo")
public class DaoConfiguration {
/* Some tricks with EntityManager also */
}
@Repository
public interface SomethingRepo extends JpaRepository<Something, Long> {
/* + some default methods */
}
但是我已经运行了代码:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'blah.blah.blah.dao.repo.SomethingRepo' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
为什么我的代码无法创建bean?可能是什么原因?
答案 0 :(得分:0)
仍然不知道为什么会有这种行为,但是我发现解决方案添加了注释
@EnableJpaRepositories(basePackageClasses = {SomethingRepo.class})
到Application.class
