1.集成Mybatis Generator

      在pom.xml中添加如下代码：（在plugins里面）

<!-- mybatis generator 自动生成代码插件 -->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.4.0</version>
                <configuration>
                    <configurationFile>src/main/resources/generator/generator-config.xml</configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>8.0.22</version>
                    </dependency>
                </dependencies>
            </plugin>

       generator-config.xml中的文件如下：

<?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="Mysql" targetRuntime="MyBatis3" defaultModelType="flat">

        <!-- 自动检查关键字，为关键字增加反引号 -->
        <property name="autoDelimitKeywords" value="true"/>
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <!--覆盖生成XML文件-->
        <plugin type="org.mybatis.generator.plugins.UnmergeableXmlMappersPlugin" />
        <!-- 生成的实体类添加toString()方法 -->
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>

        <!-- 不生成注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://rm-uf6470s9615e13hc4no.mysql.rds.aliyuncs.com:3306/wikidev?serverTimezone=Asia/Shanghai"
                        userId="wikidev"
                        password="wikidevABC123">
        </jdbcConnection>

        <!-- domain类的位置 -->
        <javaModelGenerator targetProject="src\main\java"
                            targetPackage="com.jiawa.wiki.domain"/>

        <!-- mapper xml的位置 -->
        <sqlMapGenerator targetProject="src\main\resources"
                         targetPackage="mapper"/>

        <!-- mapper类的位置 -->
        <javaClientGenerator targetProject="src\main\java"
                             targetPackage="com.jiawa.wiki.mapper"
                             type="XMLMAPPER"/>

        <table tableName="demo" domainObjectName="Demo"/>
    </context>
</generatorConfiguration>

         增加一个maven的启动命令：
