SpringBoot的FeignClient实现远程服务调用

在注册中心对FeignClient进行配置：

@EnableTransactionManagement
@SpringBootApplication
@EnableDiscoveryClient
@ComponentScan(basePackages = "com.XXXX")
@EnableScheduling
@EnableFeignClients
public class CmbsTaskApplication extends BaseApplication {
   
    /**
     *<restTemplate>.
     *<装配一个全局单例RestTemplate Spring Bean用于负载均衡远程调用>
     * @return [返回类型说明]
     * @exception/throws [违例类型] [违例说明]
     * @author jianghao
     */
    @Bean("cmbsTaskRestTemplate")
    @LoadBalanced
    public RestTemplate cmbsTaskRestTemplate() {
        return new RestTemplate();
    }

    public static void main(String[] args) {
        SpringApplication.run(CmbsTaskApplication.class, args);
    }
}

在使用中，可以在多个微服中找到想要的服务：

@FeignClient(name = "rainbow-stone-video", fallbackFactory = RainbowStoneVideoFallback.class, configuration = TSGAbilitityPlatformConfig.class)
public interface RainbowStoneVideoFeignClient {

/**
* <MM订购续订接口>
*
* @param request
* @return [返回回调结果]
* @author zhengzm
*/
@RequestMapping(value = "/video/inner/mmSubscribe", produces = MediaType.APPLICATION_JSON_UTF8_VALUE, consumes = MediaType.APPLICATION_JSON_UTF8_VALUE, method = RequestMethod.POST)
String mmSubscribe(@RequestBody MmOutSubscribeReq request);

}
