问题:
在springboot下配置好zuul的依赖后,启动报错:
Description:
The bean 'counterFactory', defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulServerAutoConfiguration$ZuulCounterFactoryConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulServerAutoConfiguration$ZuulMetricsConfiguration.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
Process finished with exit code 1
原因:
springboot和zuul的版本不兼容,springboot版本太高了,zuul的版本相对低很多
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-zuul -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>
解决方案:
更换springboot版本为2.0.5或2.0.6,可以正常运行。
