技术汇总：第十五章：MyBatisGenerator数据层代码生成

第一步：pom.xml

    <dependencies>
            <dependency>
                <groupId>com.macro.mall</groupId>
                <artifactId>mall-common</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
            <!-- MyBatis 生成器 -->
            <dependency>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-core</artifactId>
                <version>1.3.3</version>
            </dependency>
            <!-- MyBatis-->
            <dependency>
                <groupId>org.mybatis</groupId>
                <artifactId>mybatis</artifactId>
                <version>3.4.6</version>
            </dependency>
            <!--Mysql数据库驱动-->
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>8.0.15</version>
            </dependency>
    </dependencies>

第二步：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>
        <properties resource="generator.properties"/>
        <context id="MySqlContext" targetRuntime="MyBatis3" defaultModelType="flat">
            <property name="beginningDelimiter" value="`"/>
            <property name="endingDelimiter" value="`"/>
            <property name="javaFileEncoding" value="UTF-8"/>
            <!-- 为模型生成序列化方法-->
            <plugin type="org.mybatis.generator.plugins.SerializablePlugin"/>
            <!-- 为生成的Java模型创建一个toString方法 -->
            <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>
            <commentGenerator type="com.macro.mall.CommentGenerator">
                <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
                <property name="suppressAllComments" value="true"/>
                <property name="suppressDate" value="true"/>
                <property name="addRemarkComments" value="true"/>
            </commentGenerator>
     
            <jdbcConnection driverClass="${jdbc.driverClass}"
                            connectionURL="${jdbc.connectionURL}"
                            userId="${jdbc.userId}"
                            password="${jdbc.password}">
                <!--解决mysql驱动升级到8.0后不生成指定数据库代码的问题-->
                <property name="nullCatalogMeansCurrent" value="true" />
            </jdbcConnection>
     
            <javaModelGenerator targetPackage="com.macro.mall.model" targetProject="mall-mbg\src\main\java"/>
     
            <sqlMapGenerator targetPackage="com.macro.mall.mapper" targetProject="mall-mbg\src\main\resources"/>
     
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.macro.mall.mapper"
                                 targetProject="mall-mbg\src\main\java"/>
            <!--生成全部表tableName设为%-->
            <table tableName="%">
                <generatedKey column="id" sqlStatement="MySql" identity="true"/>
            </table>
        </context>
    </generatorConfiguration>

第三步：generator.properties
