Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'eurekaClient' defined in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration$EurekaClientConfiguration.class]:
Unsatisfied dependency expressed through method 'eurekaClient' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'eurekaApplicationInfoManager' defined in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration$EurekaClientConfiguration.class]:
Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException:
Failed to instantiate [com.netflix.appinfo.ApplicationInfoManager]: Factory method 'eurekaApplicationInfoManager' threw exception;
nested exception is java.lang.NullPointerException

主要原因是docker-compose.yml文件里设置的环境变量没有找到对应的值,默认赋空 导致启动报错!

把环境变量值设置即可解决
