微服務提供者-支付Module模組構建
阿新 • • 發佈：2021-10-10
微服務模組流程：
1.建module
右鍵父工程，選擇New中的Module。
輸入模組名稱。點選【Finish】。
建好的結構如下：
2.改POM
檢視父工程的POM檔案，看看變化。在父POM中多了modules節點。
選擇modeul中的pom，新增引入配置：
<?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"

</project>
3.寫YML
新建yml檔案。在modul中找到main下的resources右鍵新建file。輸入“application.yml”
application.yml配置資訊為：
server: port: 8001 spring: application: name: cloud-payment-service datasource: type: com.alibaba.druid.pool.DruidDataSource driver-class-name: org.gjt.mm.mysql.Driver url: jdbc:mysql://localhost:3306/standarddb?userUnicode=true&characterEncoding=utf-8&useSSL=false username: sa password: HRBJYKJ-Battery mybatis: mapper-locations: classpath:mapper/*.xml type-aliases-package: com.atguigu.springcloud.entities
注：如果type：com.alibab.druid.pool.DruidDataSource爆紅，則在mave中重新下載一下即可。
4.主啟動
在main的java右鍵新建Java Class。
輸入名稱："com.ckfuture.springcloud.PaymentMain8001"。
修改類程式碼：
package com.ckfuture.springcloud;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @descrption： 主啟動類
* @author： CKFuture
* @since： 2021-10-09 21:18
* @version： v1.0
* @LastEditTime：
* @LastEditors：
* @copyright： hrbckfuture.com
*/
@SpringBootApplication
public class PaymentMain8001 {
private static final Logger logger = LoggerFactory.getLogger(PaymentMain8001.class);
public static void main(String[] args) {
SpringApplication.run(PaymentMain8001.class,args);
logger.info("------------ API Service8001 Start Running--------------");
}
}
5.業務類
1）建立資料表
建立資料表payment。
2）entities
建立“entities”資料夾。分別建立Payment和CommonResult類。Payment為支付實體類。CommonResult為統一的返回類。
package com.ckfuture.springcloud.entities; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; import java.io.Serializable; /** * @descrption： 支付實體類 * @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> { //返回程式碼 private Integer code; //返回資訊 private String message; //返回資料 private T data; public CommonResult(Integer code,String message){ this(code,message,null); } }
3）dao
建立“dao”資料夾，並建立“PaymentDao”介面。
package com.ckfuture.springcloud.dao;
import com.ckfuture.springcloud.entities.Payment;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
@Mapper
public interface PaymentDao {
/**
* 新增
* @param payment
* @return
*/
public int create(Payment payment);
/**
* 通過id查詢資料
* @param id
* @return
*/
public Payment getPaymentById(@Param("id") Long id);
}
在resources中建立mapper資料夾，並建立“PaymentMapper.xml”檔案，用於實現PaymentDao介面。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.ckfuture.springcloud.dao.PaymentDao">
<resultMap id="BaseResultMap" type="com.ckfuture.springcloud.entities.Payment">
<id column="id" property="id" jdbcType="BIGINT"/>
<id column="serial" property="serial" jdbcType="VARCHAR"/>
</resultMap>
<insert id="create" parameterType="com.ckfuture.springcloud.entities.Payment" useGeneratedKeys="true" keyProperty="id">
insert into payment(serial) values(#{serial});
</insert>
<select id="getPaymentById" parameterType="Long" resultMap="BaseResultMap">
select * from where id= #{id};
</select>
</mapper>
4）service
建立“service”資料夾，並建立“PaymentService”介面。
package com.ckfuture.springcloud.service; import com.ckfuture.springcloud.entities.Payment; import org.apache.ibatis.annotations.Param; /** * @descrption： 支付服務介面 * @author： CKFuture * @since： 2021-10-09 22:26 * @version： v1.0 * @LastEditTime： * @LastEditors： * @copyright： hrbckfuture.com */ public interface PaymentService { /** * 新增 * @param payment * @return */ public int create(Payment payment); /** * 通過id查詢資料 * @param id * @return */ public Payment getPaymentById(@Param("id") Long id); }
建立“impl”資料夾，並建立“PaymentServiceImpl”實現類。
package com.ckfuture.springcloud.service.impl; import com.ckfuture.springcloud.dao.PaymentDao; import com.ckfuture.springcloud.entities.Payment; import com.ckfuture.springcloud.service.PaymentService; import org.springframework.stereotype.Service; import javax.annotation.Resource; /** * @descrption： 支付服務介面實現類 * @author： CKFuture * @since： 2021-10-09 22:26 * @version： v1.0 * @LastEditTime： * @LastEditors： * @copyright： hrbckfuture.com */ @Service public class PaymentServiceImpl implements PaymentService { @Resource private PaymentDao paymentDao; public int create(Payment payment){ return paymentDao.create(payment); } public Payment getPaymentById(Long id){ return paymentDao.getPaymentById(id); } }
5）controller
新建“controller”資料夾，並建立“PaymentController”類。
package com.ckfuture.springcloud.controller; import com.ckfuture.springcloud.entities.CommonResult; import com.ckfuture.springcloud.entities.Payment; import com.ckfuture.springcloud.service.PaymentService; 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.PostMapping; import org.springframework.web.bind.annotation.RestController; import javax.annotation.Resource; @RestController @Slf4j public class PaymentController { @Resource private PaymentService paymentService; @PostMapping(value = "/payment/create") public CommonResult create(Payment payment){ int result = paymentService.create(payment); log.info("*****插入結果："+result); if(result > 0){ return new CommonResult(200,"插入資料庫成功",result); }else { return new CommonResult(301,"插入資料庫失敗",null); } } @GetMapping(value = "/payment/get/{id}") public CommonResult getPaymentById(@PathVariable("id") Long id){ Payment payment = paymentService.getPaymentById(id); log.info("*****查詢結果："+payment); if(payment != null){ return new CommonResult(200,"查詢成功",payment); }else { return new CommonResult(301,"沒有對應記錄，查詢Id:"+id,null); } } }
6.測試
啟動8001服務
瀏覽器資料測試介面，得到查詢資料。
利用postman測試插入
