你换个spring cloud版本试试看吧，或者先从这段错误一层层debug进去排查。

dubbo可以这样做是因为dubbo的接口在服务端和消费端是通用的。 但是springcloud的消费端接口要@FeignClient等注解，不通用。[/quote] 大神你在帮忙看看

@RestController
@RequestMapping("/playerService")
public class PlayerServiceImpl implements PlayerService{

	@Override
	@RequestMapping("/all")
	public List<Player> getList(@RequestParam("name") String name) {
		Player player = new Player();
		player.setName(name);
		player.setDate(new Date());
		player.setId(1);
		player.setPoints(28.7);
		List<Player> list = new ArrayList<Player>();
		list.add(player);
		return list;
	}

}



@FeignClient(value="spring-cloud-provider")
public interface PlayerServiceConsumer extends PlayerService{
	
	@RequestMapping(value="/playerService/all",method=RequestMethod.GET)
	public List<Player> getList(@RequestParam("name") String name);
}
多贴出一个服务提供方的代码 现在是这个结构但是异常的信息还是一样的

[/quote] 不好意思看错了，spring cloud是基于RESTful风格的. /playerService/all这个地址应该写你服务提供方的地址。 PlayerService这个类没什么用，可以不继承的。[/quote] 我是希望可以类似于dubbo，定义一个API工程存放实体类型和接口，但是在项目启动时候总是会异常

输入框限制了字符串的长度，这里是剩下的错误信息代码
Spring Cloud OpenFeign 使用示例
Spring Cloud OpenFeign 示例代码工程。该工程基于官方示例（https://github.com/spring-cloud-samples/feign-eureka），额外添加了注册中心模块feign-eureka-central（eureka is running on http://localhost:8761）。官方示例工程jdk代码环境为jdk-17，由于我本地环境为jdk-8，所以调整了示例工程中的依赖版本信息，使示例工程能在jdk-8的环境下正常运行。本示例在官方示例的基础上，添加了FeignClient初始化的方式，共计2种供参考，名称为：FeignClientWarmup、LoadBalancerClientsInitializer，主要解决FeignClient客户端第一次调用慢问题，详细说明参见feign-eureka工程中feign-eureka-hello-client模块。
