消费者订单模块
1.建module
2.改POM

3.建yml
server:
port: 80
4.主启动
右键java新建class
package com.ckfuture.springcloud;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @descrption： 消费者主启动类
* @author： CKFuture
* @since： 2021-10-11 20:13
* @version： v1.0
* @LastEditTime：
* @LastEditors：
* @copyright： hrbckfuture.com
*/
@SpringBootApplication
public class OrderMain80 {
private static final Logger logger = LoggerFactory.getLogger(OrderMain80.class);
public static void main(String[] args) {
SpringApplication.run(OrderMain80.class,args);
logger.info("------------ OrderMain80 Start Running--------------");
}
}
5.业务实现类
5.1 建立两个实体类，Payment和CommonResult
package com.ckfuture.springcloud.entities;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
/**
* @descrption： 支付实体类
* @author： CKFuture
* @since： 2021-10-09 21:35
* @version： v1.0
* @LastEditTime：
* @LastEditors：
* @copyright： hrbckfuture.com
*/
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Payment implements Serializable {
private Long id;
private String serial;
}
package com.ckfuture.springcloud.entities;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class CommonResult<T>
{
//返回代码
private Integer code;
//返回信息
private String message;
//返回数据
private T data;
public CommonResult(Integer code,String message){
this(code,message,null);
}
}
5.2 建立OrderController类
如何在80的controller中调用 8001端口服务呢，这里用到RestTemple。
知识点：
RestTemplate提供了多种便捷访问远程Http服务的方法，是一种简单便捷的访问restful服务模板类，是Spring提供的用于访问Rest服务的客户端模板工具集。
5.3 建立一个ApplicationContextConfig配置类
package com.ckfuture.springcloud.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;
/**
* @descrption： 配置类
* @author： CKFuture
* @since： 2021-10-11 20:29
* @version： v1.0
* @LastEditTime：
* @LastEditors：
* @copyright： hrbckfuture.com
*/
@Configuration
public class ApplicationContextConfig {
/**
* RestTemplate
* @return
*/
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
}
5.4 OrderController代码编写
package com.ckfuture.springcloud.controller;
import com.ckfuture.springcloud.entities.CommonResult;
import com.ckfuture.springcloud.entities.Payment;
import io.swagger.annotations.Api;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import javax.annotation.Resource;
/**
* @descrption： 消费者控制类
* @author： CKFuture
* @since： 2021-10-11 20:52
* @version： v1.0
* @LastEditTime：
* @LastEditors：
* @copyright： hrbckfuture.com
*/
@Api(tags={"消费者接口"})
@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){
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);
}
}
6.测试
启动 8001和80服务
读取测试：
插入测试：
数据库结果：
通过80服务访问8001服务获取结果，亲测成功！！大河弯弯向东流就是这么牛（门儿~）
7.关于开启RunDashboard
IDEA在微服务测试时候，有的是不自动开启RunDashboard的，需要在workspace.xml中增加组件。
<component name="RunDashboard">
<option name="configurationTypes">
<set>
<option value="SpringBootApplicationConfigurationType"/>
</set>
</option>
<option name="ruleStates">
<list>
<RuleState>
<option name="name" value="ConfigurationTypeDashboardGroupingRule" />
</RuleState>
<RuleState>
<option name="name" value="StatusDashboardGroupingRule" />
</RuleState>
</list>
</option>
</component>
保存后，关闭IDEA重新打开。
