• 增加wallet模塊胸竞，提供接口 /getWallet欺嗤，并注冊(cè)到eureka-server
• account模塊增加接口 /userInfo，通過調(diào)用wallet接口 /getWallet 獲取數(shù)據(jù)后返回

配置文件 application.properties

# 端口號(hào)
# 端口號(hào)
server.port=8001

# 服務(wù)名
spring.application.name=wallet

# eureka服務(wù)注冊(cè)中心地址
eureka.client.serviceUrl.defaultZone=http://localhost:5000/eureka/

啟動(dòng)類 MainApplication

@EnableEurekaClient
@SpringBootApplication
@RestController
@RequestMapping
public class MainApplication {

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


    @GetMapping("getWallet")
    public String getWallet() {
        return "this is wallet info";
    }

}

啟動(dòng)服務(wù)

訪問 http://localhost:8001/

圖中可以看出卫枝，wallet接口可以正常訪問

修改account

增加Feign依賴

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-feign</artifactId>
        </dependency>

增加Feign支持與userInfo接口

@EnableEurekaClient
@SpringBootApplication
@RestController
@RequestMapping
@EnableFeignClients
public class MainApplication {

    @Autowired
    private WalletRemoteService walletRemoteService;

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

    @GetMapping("userInfo")
    public Map userInfo() {
        String walletInfo = walletRemoteService.getWallet();
        return new HashMap() {{
            put("walletInfo", walletInfo);
        }};
    }

}

測(cè)試

訪問 http://localhost:5000/

account煎饼、wallet已成功注冊(cè)到eureka-server中

訪問 http://localhost:8000/userInfo

account調(diào)用wallet成功
