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

• 注意：不要忘记@RequestBody注解
• 测试

1、建cloud-consumer-order80

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>springcloud2020</artifactId>
        <groupId>com.sl.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cloud-consumer-order80</artifactId>
    <dependencies>
        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web -->
        <dependency>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web  -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-devtools -->

            <optional>true</optional>
        </dependency>

            <artifactId>lombok</artifactId>

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


</project>

3、写YML

server:
  port: 80

4、主启动

package com.sl.springcloud;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

5、业务类
①创建entities(将cloud-provider-payment8001工程下的entities包下的两个实体类复制过来)

②config配置类

//RestTemplate的配置文件
@Configuration
public class ApplicationContextConfig {

    @Bean
    public RestTemplate getRestTemplate() {//放一个RestTemplate对象到bean容器里面，便于以后操作
        return new RestTemplate();
    }
}

③创建controller

@Slf4j
@RestController

public class OrderController {
    public static final  String PAYMENT_URL="http://localhost:8001";//生产者的地址

    @Resource
    private RestTemplate restTemplate;//利用restTemplate去调用8001服务

    @GetMapping("/consumer/payment/create")
    public CommonResult   create(payment payment){
        return restTemplate.postForObject(PAYMENT_URL+"/payment/create",payment,CommonResult.class);  //写操作
    }

    @GetMapping(value = "/consumer/payment/get/{id}")
    public CommonResult getPayment(@PathVariable("id") Long id){

        return  restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class);//读操作
    }


}

注意：不要忘记@RequestBody注解

测试

先启动cloud-provider-payment8001
再启动cloud-consumer-order80

访问http://localhost/consumer/payment/get/32
http://localhost/consumer/payment/create\?serial=“你好啊？？”
