引入依赖

• mybatis-spring-boot-starter
• mybatis-generator-core

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.4</version>
</dependency>
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.7</version>
</dependency>

引入mvn插件

• 打包插件
• 代码生成插件

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.7</version>
            <configuration>
                <configurationFile>src/main/resources/mybatis-generator-config.xml</configurationFile>
                <overwrite>true</overwrite>
                <includeCompileDependencies>true</includeCompileDependencies>
            </configuration>
        </plugin>
    </plugins>
</build>

编写代码生成的配置文件mybatis-generator-config.xml

            <property name="trimStrings" value="true" />

        <javaClientGenerator type="XMLMAPPER" targetPackage="com.qiuyi.springdemo.dao"  targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>


        <!-- List of tables to inspect -->
        <table schema="" tableName="t_coffee" domainObjectName="Coffee" />
    </context>
</generatorConfigura

运行结果

双击执行右边的mybatis-generator:generate ，将自动生成三个文件夹：

• dao
• model
• mapper
