spring feign客户端异常处理

@Component
public class CustomErrorDecoder implements ErrorDecoder {

    @Override
    public Exception decode(String methodKey, Response response) {
        // 根据响应状态码和响应内容判断异常类型，并返回对应的自定义异常
        if (response.status() == 404) {
            return new ResourceNotFoundException("Remote resource not found");
        } else if (response.status() == 500) {
            return new RemoteServiceException("Remote service encountered an internal error");
        }
        
        // 返回默认异常
        return new FeignException.Default(methodKey, response);
    }
}

@FeignClient(name = "example-service", configuration = CustomErrorDecoder.class)
public interface ExampleServiceClient {
    // 远程调用方法
    // ...
