mybatis generator快速構建

（1）首先導入maven dependency依賴

      <!-- 自動生成 -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.7</version>
        </dependency>

 (2)配置plugin

<!-- 自動生成 -->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <configuration>
                    <!--允許移動生成的文件 -->
                    <verbose>true</verbose>
                    <!-- 是否覆蓋 -->
                    <overwrite>true</overwrite>
                </configuration>

                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>8.0.16</version>
                    </dependency>
                </dependencies>
            </plugin>

(3)編寫generatorConfig.xml(這個名字是寫死的，一定要這樣寫)

<?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>
    <!-- 一個數據庫一個context -->
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!-- 配置數據庫連接 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test?useSSL=false&amp;useAffectedRows=true&amp;characterEncoding=UTF-8&amp;serverTimezone=Asia/Shanghai"
                        userId="root" password="123456">
        </jdbcConnection>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- 指定javaBean生成的位置 -->
        <javaModelGenerator targetPackage="zhaoyy.demo.entity.user" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!--指定mapping.xml映射文件生成的位置 -->
        <sqlMapGenerator targetPackage="mybatis\mapper\user" targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- 指定dao接口生成的位置，mapper接口 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="zhaoyy.demo.mapper.user"
                             targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- table指定每個表的生成策略 -->
        <table tableName="mac_site_layouts" domainObjectName="SiteLayout"/>
    </context>
</generatorConfiguration>
