FeignClient实现跨服务之间调用

首先在A服务写好接口

新建这几个包跟类

@FeignClient(contextId = "remoteSysDictService", value = ServiceNameConstants.AMS_SERVICE, fallbackFactory = RemoteSysDictServiceFallbackFactory.class)
public interface RemoteSysDictService {

	@GetMapping("/sysdict/getOwsInfromByType")
	R getOwsInfromByType();
}

@Slf4j
@Component
public class RemoteSysDictServiceFallbackImpl implements RemoteSysDictService {
	@Override
	public R getOwsInfromByType() {
		return null;
	}
}

@Component
public class RemoteSysDictServiceFallbackFactory implements FallbackFactory<RemoteSysDictService> {
	@Override
	public RemoteSysDictService create(Throwable cause) {
		RemoteSysDictServiceFallbackImpl remoteSysDictServiceFallback = new RemoteSysDictServiceFallbackImpl();
		return remoteSysDictServiceFallback;
	}
}

在resource添加spring.factories

配置路径

在B服务直接调用即可
