springcloud之Feign初识篇—根路径导致404问题

我们的服务提供者很对时候会配置**server.servlet.context-path**此时我们按照之前的feign配置去请求服务提供者的话会报404，无法找到请求路径。

我们在@FeignClient的请求路径上添加根路径信息(**有时会报错**)：

@FeignClient(name = "test1",configuration = FeignClientsConfiguration.class)
    public interface FeignTest1Service {
        @RequestMapping(value = "/eureka-clinet1/ribbonTest",method = RequestMethod.POST)
        public String testFeign(@RequestBody Map<String,String> map);
    }

我们可以在@FeignClient上配置**path**属性，设置根路径【推荐设置这个】

import org.springframework.cloud.openfeign.FeignClient;
    import org.springframework.cloud.openfeign.FeignClientsConfiguration;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    import java.util.Map;
    
    
    @FeignClient(name = "test1",path ="eureka-clinet1",configuration = FeignClientsConfiguration.class)
    public interface FeignTest1Service {
    
        @RequestMapping(value = "/ribbonTest",method = RequestMethod.POST)
        public String testFeign(@RequestBody Map<String,String> map);
    }

运行：
