①使用JAVA代码

 pom.xml只需要加入依赖，不用添加mvn插件mybatis-generator-maven-plugin

        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.7</version>
        </dependency>

    public static void main(String[] args) {
        System.out.println("-------------------Hello World!  Ready To MybatisGenerator!");
        try {
            generator();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void generator() throws Exception {
        List<String> warnings = new ArrayList<String>();
        File configFile = new File("src\main\resources\mybatis-generator\generatorConfig.xml");// the path of the 'generatorConfig.xml'
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(true);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
        // 输出 warning 日志
        warnings.forEach(System.out::println);
        System.out.println("-------------------MybatisGenerator Succeed!");
    }

②使用mvn插件

pom.xml需要加入mvn插件mybatis-generator-maven-plugin

命令：mvn mybatis-generator:generate

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.7</version>
    <configuration>
        <configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile> 指定xml路径
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
    <executions>
        <execution>
            <id>Generate MyBatis Artifacts</id>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.7</version>
        </dependency>
    </dependencies>
</plugin>
