  • spring cloud feign 调用接口报错"No message available

    There was an unexpected error (type=Internal Server Error, status=500).
    status 404 reading HelloService#hello(); content: {"timestamp":"2018-08-22T09:28:56.585+0000","status":404,"error":"Not Found","message":"No message available","path":"/hello"}
     
    解决方案:
    原来是引入pom.xml 文件的问题,将配置
     
    <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
    </dependency>

    删掉就可以了,原理就不清楚,请大神们帮着分析一下

    正确的配置文件如下:
