1.pom.xml文件中配置generator插件

<plugins>
    <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.5</version>

        <dependencies>
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.17</version>
            </dependency>
        </dependencies>
        
        <configuration>
            <!--配置文件的路徑-->
            <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
            <verbose>true</verbose>
            <overwrite>true</overwrite>
        </configuration>
    </plugin>
</plugins>

易錯點：逆向工程的<plugins>標籤與maven生命週期插件的<pluginManagement>標籤是平級的！

2.generatorConfig.xml的配置

3.生成文件

點擊右側Maven--Plugins下的mybatis-generator直接生成pojo類、mapper接口和mapper.xml文件。
