请教DEMO相关问题

[biyisi]

开发者您好， 根据Wiki所示，provider的impl继承的是UserRestService，看代码里是UserService，请问是否是写错了。 另外，看DEMO里UserService类并没有添加@RequestMapping和@GetMapping，这样客户端通过httprest调用服务端是不是无法做到？ 我用两个SpringBoot项目，分别作为客户端和服务端，客户端和服务端使用了代码一模一样的UserService和UserServiceImpl。我在UserRestServiceImpl中注释掉了rest调用。通过curl调用客户端的GET方法，返回值报错：

"Server failed to execute target method, cause by: StarlightRpcException, Service {com.example.clientdemo.service.UserService} not found in provider"

而我看客户端报错如下：

服务端有控制台输出：

请教该如何处理？客户端和服务端应当是分开的，很难像您DEMO一样是同一个文件，只能保证文件内容相同。

另外我这里服务启动后一直报错，似乎并不影响使用，也想请教您该如何处理？：

盼能得到您的答复，谢谢

服务端：com.example.demo_0313.service.UserService和UserServiceImpl 客户端：com.example.clientdemo.service.UserService和UserServiceImpl

我在客户端新建软件包，把类路径改为com.example.demo_0313.service.UserService和UserServiceImpl之后可以完成调用。 如果这边需要保证客户端和服务端包括路径在内UserService完全相同，这样是不是不太合理？还是有其他处理办法？

当我修改服务端的UserService代码添加@RequestMapping("/user")和@GetMapping后，启用客户端的rest调用，通过8777可以调用服务端getUser方法，但是通过8666调用时，会报错如下： "Server failed to execute target method, cause by: NoClassDefFoundError, Could not initialize class com.baidu.cloud.thirdparty.feign.Util"

客户端报错如下： `已经进入了, userId = 1 2023-03-14 18:37:32.452 ERROR 29980 --- [ star-s-biz-2] c.b.c.s.core.rpc.RpcServiceInvoker : Failed to execute method getUser, caused by
