# RocketMQ 实战：模拟电商网站场景综合案例（五）

RocketMQ 实战：模拟电商网站场景综合案例（五）

一、mybatis 逆向工程使用

4、逆向工程生成的 .xml 配置文件。

4.1、生成的 TradeCouponMapper.xml 文件。

5、创建 shop-pojo 实体类工程，复制导入生成的 POJO 类文件。

5.1、在 pom.xml 中，导入依赖坐标。


<?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>shop-parent</artifactId><groupId>com.iteima.shop</groupId><version>1.0-SNAPSHOT</version><relativePath>../shop-parent/pom.xml</relativePath></parent><modelVersion>4.0.0</modelVersion><artifactId>shop-pojo</artifactId></project>
<!-- shop\shop-pojo\pom.xml -->

5.2、创建类 MQEntity.java

package com.itheima.entity;import java.math.BigDecimal;public class MQEntity {private Long orderId;private Long couponId;private Long userId;private BigDecimal userMoney;private Long goodsId;private Integer goodsNum;public Long getOrderId() {return orderId;}public void setOrderId(Long orderId) {this.orderId = orderId;}public Long getCouponId() {return couponId;}public void setCouponId(Long couponId) {this.couponId = couponId;}public Long getUserId() {return userId;}public void setUserId(Long userId) {this.userId = userId;}public BigDecimal getUserMoney() {return userMoney;}public void setUserMoney(BigDecimal userMoney) {this.userMoney = userMoney;}public Long getGoodsId() {return goodsId;}public void setGoodsId(Long goodsId) {this.goodsId = goodsId;}public Integer getGoodsNum() {return goodsNum;}public void setGoodsNum(Integer goodsNum) {this.goodsNum = goodsNum;}
}

5.3、创建类 Result.java

package com.itheima.entity;import java.io.Serializable;/*** 结果实体类*/
public class Result implements Serializable {private Boolean success;private String message;public Result() {}public Result(Boolean success, String message) {this.success = success;this.message = message;}public Boolean getSuccess() {return success;}public void setSuccess(Boolean success) {this.success = success;}public String getMessage() {return message;}public void setMessage(String message) {this.message = message;}@Overridepublic String toString() {return "Result{" +"success=" + success +", message='" + message + '\'' +'}';}
}
