SpringCloud第四天

                                       Nacos 整合SpringCloud

 

1 新建一個module fourday ，在fourday 下面新建一個功能provider工程。

2 pom如下

<dependencies>

    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <version>2.1.1.RELEASE</version>
        <type>pom</type>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

3  properties如下

server.address=0.0.0.0
server.port=8093
spring.application.name=zyk-provider
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

4 啓動類如下 

@SpringBootApplication
@EnableDiscoveryClient
public class Provider {
    public static void main(String[] args) {
        SpringApplication.run(Provider.class,args);
    }
}

5 controller 如下

@RestController
public class ProviderController {
    @RequestMapping("/provider/{name}")
    public String testProvider (@PathVariable String name) {
        return "Hello Discovery 8093" +name;
    }
}

6 啓動 程序  訪問 http://localhost:8093/provider/nihao 測試程序是否正常

 

 

7 在fourday下面創建customer 工程。

  pom和 provider一樣

 8 application.properties 如下

server.port=8092
spring.application.name=zyk-service-customer
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

9 customer 的啓動類如下

@SpringBootApplication
@EnableDiscoveryClient
public class FourDayCustomer {

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

10 controller 如下

@RestController
public class TestCustomerController {
    @LoadBalanced
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
    @Autowired
    private  RestTemplate restTemplate;


    @GetMapping(value = "/test/{str}")
    public String echo(@PathVariable String str) {
        return restTemplate.getForObject("http://zyk-provider/provider/" + str, String.class);
    }
}

11 測試 地址 http://localhost8092/test/nihao 查看結果。

12 啓動多個 provider節點  

13 測試 地址 http://localhost8092/test/nihao 查看結果。
