04_4-cloud-consumer-order80 微服务消费者订单Module模块

1、建 cloud-consumer-order80

2、改 pom

<dependencies>
    
    <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>

</denpendencies>

3、写 yml

server:
    port: 80

4、主启动

@SpringBootApplication
public class OrderMain80 {

    public static void main(String[] args) {
        SpringApplication.run(OrderMain80.class, args);
    }
}

5、业务类

• 1、entities 包下的两个类——CommonResult、Payment

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Payment implements Serializable {
    
    private Long id;
    private String serial;
}

@Data
@AllArgsConstructor
@NoArgsConstructor
public class CommonResult<T> {

    private Integer code;
    private String message;
    private T       data;
    
    public CommonResult(Integer code, String message) {
        this(code, message, null);
    }
}

• 2、config配置类——RestTemplate 类
  

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

• 3、controller
  

@RestController
@Slf4j
public class OrderController {
    // 这里的 url 根据自己的来写
    public static final String PAYMENT_URL = "http://localhost:8001";
    
    @Resource
    private RestTemplate restTemplate;
    
    @GetMapping("/consumer/payment/create")
    public CommonResult<Payment> create(Payment payment) {
        return restTemplate.postForObject(PAYMENT_URL + "/payment/create", 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);
    }
}
