Spring 引导:bean 定义名称重复

Spring boot: bean definition name duplicated

我在服务开始时收到下一条消息:

ConflictingBeanDefinitionException: Annotation-specified bean name 'estatRegistreServiceImpl' for bean class [cat.gencat.catsalut.hes.mpi.api.loader.service.EstatRegistreServiceImpl] conflicts with existing, non-compatible bean definition of same name and class [cat.gencat.catsalut.hes.mpi.api.admin.service.impl.EstatRegistreServiceImpl]

Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'estatRegistreServiceImpl' for bean class [cat.gencat.catsalut.hes.mpi.api.loader.service.EstatRegistreServiceImpl] conflicts with existing, non-compatible bean definition of same name and class [cat.gencat.catsalut.hes.mpi.api.admin.service.impl.EstatRegistreServiceImpl]

目前,我创建了两个包含我的服务的包:

src/main/java/cat/gencat/catsalut/hes/mpi/api/admin/service/
src/main/java/cat/gencat/catsalut/hes/mpi/api/loader/service/

src/main/java/cat/gencat/catsalut/hes/mpi/api/admin/service/

src/main/java/cat/gencat/catsalut/hes/mpi/api/admin/service/
├── EstatRegistreService.java
├── impl
    ├── EstatRegistreServiceImpl.java

src/main/java/cat/gencat/catsalut/hes/mpi/api/loader/service/
├── EstatRegistreService.java
├── impl
    ├── EstatRegistreServiceImpl.java

两个 bean 都使用相同的名称注册:estatRegistreServiceImpl

我知道我可以使用 @Service 注释设置注册名称。我不想保留这些字符串文字,因为我有很多类似服务的 类.

有没有不使用 @Service("service1") and @Service("service2)` 的方式获取它?

谢谢

好吧,您可以创建自定义 bean 名称生成器。它将在注册 bean 时添加完整的限定符路径。

这里我已经实现了 ApplicationRunner 接口只是为了说明 bean 的名字是什么!

@SpringBootApplication
@ComponentScan(nameGenerator = YourMainApplication.CustomGenerator.class)
public class YourMainApplication extends SpringBootServletInitializer implements ApplicationRunner {

    @Autowired
    private ApplicationContext context;

    public static void main(String[] args) {
        SpringApplication.run(YourMainApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(YourMainApplication.class);
    }

    public static class CustomGenerator extends AnnotationBeanNameGenerator {
        @Override
        public String generateBeanName(BeanDefinition definition, BeanDefinitionRegistry registry) {
            return definition.getBeanClassName();
        }
    }

    @Override
    public void run(ApplicationArguments args) {
        String[] allServiceBeansNames = context.getBeanNamesForAnnotation(Service.class);
        for(String beanName : allServiceBeansNames) {
            System.out.println(beanName);
        }
    }
}
