Eureka切换Nacos时发现两个注册中心的解决方法

多少学一点吧2024-01-11 7:00

报错信息如下，意思是发现了两个注册中心

java 复制代码

Field autoServiceRegistration in org.springframework.cloud.client.serviceregistry.AutoServiceRegistrationAutoConfiguration required a single bean, but 2 were found: 	
- nacosAutoServiceRegistration: defined by method 'nacosAutoServiceRegistration' in class path resource [com/alibaba/cloud/nacos/registry/NacosServiceRegistryAutoConfiguration.class] 	
- eurekaAutoServiceRegistration: defined by method 'eurekaAutoServiceRegistration' in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration.class]

首先我们看一下工程目录：

eureka-server是我的eureka服务端，order-server和user-server是我的eureka客户端，在eureka服务端中引入了服务端依赖：

java 复制代码

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

在两个eureka客户端中引入了客户端依赖：

java 复制代码

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

当我想将注册中心从eureka切换为nacos时，不仅需要注释掉eureka客户端的依赖，还需要注释掉eureka服务端的依赖。
