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

来源:互联网 发布:沙钢收购大数据 编辑:程序博客网 时间:2024/06/17 14:53

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
@Componentpublic 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);    }}
