SpringBoot2.2.X及2.3.X 集成 SpringCloud

SpringBoot2.2.X及2.3.X 集成 SpringCloud

一、pom

<!-- spring cloud eureka 注册中心-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

<!--hystrix断路器-->
<dependency>
    <groupId>com.netflix.hystrix</groupId>
    <artifactId>hystrix-javanica</artifactId>
    <version>RELEASE</version>
</dependency>

<dependency>
    <groupId>com.netflix.hystrix</groupId>
    <artifactId>hystrix-core</artifactId>
    <version>RELEASE</version>
</dependency>

<dependencyManagement>

            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Hoxton.SR1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

二、注册中心配置application.properties

#springCloud 注册中心配置
eureka.instance.hostname=localhost
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

三、客户端配置application.properties

#springCloud 注册客户端配置
eureka.client.serviceUrl.defaultZone = http://localhost:8761/eureka/
spring.application.name = FrameServer

四、调用远程接口

ResConfig

@Configuration
@Component
public class ResConfig {
    @Bean
    @LoadBalanced
    RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

五、Service

public interface RpcService {
    DetectionInfo FaceInfoDatection(String base64);
}

六、impl

@Service
public class RpcServiceImpl implements RpcService {
    @Autowired
    private RestTemplate restTemplate;

    @Autowired
    Gson gson;

    @Override
    public DetectionInfo FaceInfoDatection(String base64) {
        String data = GetFaceInfo(base64);
        if (data != null || !data.equals("err")){
            DetectionInfo detectionInfo = gson.fromJson(data,DetectionInfo.class);
            return detectionInfo;
        }
        return null;
    }



    @HystrixCommand(fallbackMethod = "error")
    public String GetFaceInfo(String base64){
        MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
        map.add("base64Str",base64);
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);
        return restTemplate.postForObject("http://AISERVER/FaceInfoDatection",request,String.class);
        return null;
    }

    public String error(String name){
        return "err";
    }

    public String error(){
        return "err";
    }
}

七、启动类

//@EnableEurekaClient 开启客户端
//@EnableEurekaServer 开启注册中心
//@EnableHystrix 开启断路器
