cloud-consumer-order80微服务消费者订单Module模块

开始吧

1、 建立模块儿

此处省去操作。

2、 整理pom文件

    <description>cloud-consumer-order80微服务消费者订单Module模块</description>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

3、 启动类

省略

4、 配置文件

# 端口号
server:
  port: 8001

5、 config配置类

@Configuration
public class ApplicationContextConfig {

    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

6、 controller类

@RestController
@Slf4j
public class OrderController {

    public static final String PAYMENT_URL= "http://localhost:8001";

    @Resource
    private RestTemplate restTemplate;

    @GetMapping("/consumer/payment/create")
    public CommonResult<Payment> create(Payment payment){
        log.info("*******消费者启动创建订单*******");
        return restTemplate.postForObject(PAYMENT_URL+"/payment/create",payment, CommonResult.class);
    }

    @GetMapping("/consumer/payment/get/{id}")
    public CommonResult<Payment> getPayment(@PathVariable("id") Long id){
        return restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class);
    }

}

7、 测试即可

细节讲解
