RocketMQ 实战：模拟电商网站场景综合案例（四）

一、mybatis 逆向工程使用。

1、创建 Mybatis-Reverse 逆向工程。

1.1、在 Mybatis-Reverse\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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.pinyougou</groupId>
    <artifactId>mybatis-reverse</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.30</version>
        </dependency>
        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.1.0</version>
        </dependency>
    </dependencies>
    
</project>
<!-- Mybatis-Reverse\pom.xml -->

1.2、创建 类 GeneratorSqlmap.java

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

public class GeneratorSqlmap {

	public void generator() throws Exception{

		List<String> warnings = new ArrayList<String>();
		boolean overwrite = true;
		File configFile = new File("E:\\RocketMQ\\资料\\Mybatis-Reverse\\src\\main\\resources\\generatorConfig.xml");
		ConfigurationParser cp = new ConfigurationParser(warnings);
		Configuration config = cp.parseConfiguration(configFile);
		DefaultShellCallback callback = new DefaultShellCallback(overwrite);
		MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
				callback, warnings);
		myBatisGenerator.generate(null);

	} 
	public static void main(String[] args) throws Exception {
		try {
			GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap();
			generatorSqlmap.generator();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

1.3、创建 配置文件 generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
	<context id="testTables" targetRuntime="MyBatis3">
		<commentGenerator>
			<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost:3306/trade" userId="root"
			password="root">
		</jdbcConnection>
		<!-- <jdbcConnection driverClass="oracle.jdbc.OracleDriver"
			connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:yycg" 
			userId="yycg"
			password="yycg">
		</jdbcConnection> -->

		<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 和 
			NUMERIC 类型解析为java.math.BigDecimal -->
		<javaTypeResolver>
			<property name="forceBigDecimals" value="false" />
		</javaTypeResolver>

		<!-- targetProject:生成PO类的位置 -->
		<javaModelGenerator targetPackage="com.itheima.shop.pojo"
			targetProject="E:\RocketMQ\资料\Mybatis-Reverse\src\main\java">
			<!-- enableSubPackages:是否让schema作为包的后缀 -->
			<property name="enableSubPackages" value="false" />
			<!-- 从数据库返回的值被清理前后的空格 -->
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置 -->
		<sqlMapGenerator targetPackage="com.itheima.shop.mapper"
			targetProject="E:\RocketMQ\资料\Mybatis-Reverse\src\main\resources">
			<!-- enableSubPackages:是否让schema作为包的后缀 -->
			<property name="enableSubPackages" value="false" />
		</sqlMapGenerator>
		<!-- targetPackage：mapper接口生成的位置 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="com.itheima.shop.mapper"
			targetProject="E:\RocketMQ\资料\Mybatis-Reverse\src\main\java">
			<!-- enableSubPackages:是否让schema作为包的后缀 -->
			<property name="enableSubPackages" value="false" />
		</javaClientGenerator>
		<!-- 指定数据库表 -->
		<table schema="" tableName="trade_coupon"></table>
		<table schema="" tableName="trade_goods"></table>
		<table schema="" tableName="trade_goods_number_log"></table>
		<table schema="" tableName="trade_order"></table>
		<table schema="" tableName="trade_pay"></table>
		<table schema="" tableName="trade_user"></table>
		<table schema="" tableName="trade_user_money_log"></table>
        <table schema="" tableName="trade_mq_consumer_log"></table>
        <table schema="" tableName="trade_mq_producer_temp"></table>

		<!-- 有些表的字段需要指定java类型
		<table schema="" tableName="">
			<columnOverride column="" javaType="" />
		</table> -->
	</context>
</generatorConfiguration>

1.4、创建 日志文件 log4j.properties

log4j.rootLogger=DEBUG, Console
#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

2、运行 GeneratorSqlmap.java ，连接数据库，逆向生成 POJO 类文件 及 mapper 类文件。

2.1、生成的 POJO 类 TradeCoupon.java

package com.itheima.shop.pojo;

import java.math.BigDecimal;
import java.util.Date;

public class TradeCoupon {
    private Long couponId;

    private BigDecimal couponPrice;

    private Long userId;

    private Long orderId;

    private Integer isUsed;

    private Date usedTime;

    public Long getCouponId() {
        return couponId;
    }

    public void setCouponId(Long couponId) {
        this.couponId = couponId;
    }

    public BigDecimal getCouponPrice() {
        return couponPrice;
    }

    public void setCouponPrice(BigDecimal couponPrice) {
        this.couponPrice = couponPrice;
    }

    public Long getUserId() {
        return userId;
    }

    public void setUserId(Long userId) {
        this.userId = userId;
    }

    public Long getOrderId() {
        return orderId;
    }

    public void setOrderId(Long orderId) {
        this.orderId = orderId;
    }

    public Integer getIsUsed() {
        return isUsed;
    }

    public void setIsUsed(Integer isUsed) {
        this.isUsed = isUsed;
    }

    public Date getUsedTime() {
        return usedTime;
    }

    public void setUsedTime(Date usedTime) {
        this.usedTime = usedTime;
    }
}

2.2、生成的 POJO 类 TradeCouponExample.java

package com.itheima.shop.pojo;

import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class TradeCouponExample {
    protected String orderByClause;

    protected boolean distinct;

    protected List<Criteria> oredCriteria;

    public TradeCouponExample() {
        oredCriteria = new ArrayList<Criteria>();
    }

    public void setOrderByClause(String orderByClause) {
        this.orderByClause = orderByClause;
    }

    public String getOrderByClause() {
        return orderByClause;
    }

    public void setDistinct(boolean distinct) {
        this.distinct = distinct;
    }

    public boolean isDistinct() {
        return distinct;
    }

    public List<Criteria> getOredCriteria() {
        return oredCriteria;
    }

    public void or(Criteria criteria) {
        oredCriteria.add(criteria);
    }

    public Criteria or() {
        Criteria criteria = createCriteriaInternal();
        oredCriteria.add(criteria);
        return criteria;
    }

    public Criteria createCriteria() {
        Criteria criteria = createCriteriaInternal();
        if (oredCriteria.size() == 0) {
            oredCriteria.add(criteria);
        }
        return criteria;
    }

    protected Criteria createCriteriaInternal() {
        Criteria criteria = new Criteria();
        return criteria;
    }

    public void clear() {
        oredCriteria.clear();
        orderByClause = null;
        distinct = false;
    }

    protected abstract static class GeneratedCriteria {
        protected List<Criterion> criteria;

        protected GeneratedCriteria() {
            super();
            criteria = new ArrayList<Criterion>();
        }

        public boolean isValid() {
            return criteria.size() > 0;
        }

        public List<Criterion> getAllCriteria() {
            return criteria;
        }

        public List<Criterion> getCriteria() {

        }

        protected void addCriterion(String condition) {
            if (condition == null) {
                throw new RuntimeException("Value for condition cannot be null");
            }
            criteria.add(new Criterion(condition));
        }

        protected void addCriterion(String condition, Object value, String property) {
