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

1、建cloud-provider-payment8001

2、改POM

 
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>cloud190805</artifactId>
        <groupId>com.atguigu.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cloud-consumer-order80</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>

        </dependency>

        </dependency>
        <dependency>

            <scope>test</scope>
        </dependency>
    </dependencies>

</project>

3、写YML

　　定义端口号

4、主启动

5、业务类

　　1、entities

　　2、config配置类（RestTemplate）

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

　　3、controller

@RestController
public class OrderController
{

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

    @Autowired
    private RestTemplate restTemplate;

    @GetMapping("/consumer/payment/create") //客户端用浏览器是get请求，但是底层实质发送post调用服务端8001
    public CommonResult create(Payment payment)
    {
        return restTemplate.postForObject(PaymentSrv_URL + "/payment/create",payment,CommonResult.class);
    }


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