最近使用springcloud微服务进行服务调用时，服务消费者调用服务提供者的服务，服务调用失败，报下面的问题

feign.FeignException: status 404 reading BumenRemote#getlistAll(String)

404 ,就是没找到服务，服务调用的路径有问题，我们看一下服务调用的方法

@FeignClient(name = "spring-cloub-consumer")
    public interface BumenRemote {
    
    
         @RequestMapping("/bumen/getlistAll")
         public String getlistAll(@RequestParam(value = "name")String name);
    
    }

最后检查代码发现，在springcloud 的配置文件中，加上了这个 **server.servlet.context-path**

server.servlet.context-path=/api-c/
    spring.application.name=spring-cloub-consumer
    mybatis.mapper-locations=classpath*:/mapper/**Mapper.xml

所以我们在服务调用的路径上，**加上 api-c/ 即可，或者去掉 server.servlet.context-path**

@FeignClient(name = "spring-cloub-consumer")
    public interface BumenRemote {
    
    
         @RequestMapping("api-c/bumen/getlistAll")
         public String getlistAll(@RequestParam(value = "name")String name);
    
    }
