*  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>
            
            <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>
    
    
    </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？？”
