SpringBoot启动时报org.springframework.context.annotation.ConflictingBeanDefinitionException解决方法

在SpringBoot应用启动的过程中，因为报org.springframework.context.annotation.ConflictingBeanDefinitionException导致应用启动失败

错误信息：

Annotation-specified bean name 'personDubboConsumerService' for bean class 
[cn.com.hellowood.dubboclient.dubbo.PersonDubboConsumerService]
 conflicts with existing, non-compatible bean definition of same name and class 
 [cn.com.hellowood.dubbo.PersonDubboConsumerService]

这是因为在应用中使用到了多个该类的对象，而该类的对象通过注解的方式注入到应用中，在注入的过程中因为对象的名称重复导致了该异常 通过指定注入对象的名称可以解决这个问题

  • 原来的代码
@Component
public class PersonDubboConsumerService {

    @Reference(version = "1.0.0")
    PersonDubboService service;

    public void sayHello() {
        String name = "哈哈哈哈";
        Person person = service.sayHello(name);
    }
}
  • 修改后（Component注解加上名称就可以，要和另一个bean的名称不同）
@Component("personConsumerService")
public class PersonDubboConsumerService {

    @Reference(version = "1.0.0")
    PersonDubboService service;

    public void sayHello() {
        String name = "哈哈哈哈";
        Person person = service.sayHello(name);
    }
}
