消费者订单模块

1.建module

 

 

 2.改POM

    </dependencies>


</project>

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。
