本文介绍如何在Maven项目中配置MyBatis Generator插件来自动生成持久层代码，包括实体类、映射文件及DAO接口等。通过具体配置示例展示了如何指定数据库连接信息、目标生成路径等关键设置。

在pom.xml中添加plugin

<build>
    <plugins>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.5</version>
            <configuration>
                <configurationFile>src/generatorConfig.xml</configurationFile>
                <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>1.3.5</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>
