Mybatis代码生成器

导入依赖

通过编码方式去运行插件先需要引入mybatis-generator-core依赖

	<dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis.generator.core</artifactId>
      <version>1.3.2</version>
    </dependency>

如果使用Maven插件，那么不需要引入mybatis-generator-core依赖，只需要引入一个Maven的插件mybatis-generator-maven-plugin

<plugins>
    <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
            <!-- 输出详细信息 -->
            <verbose>true</verbose>
            <!-- 覆盖生成文件 -->
            <overwrite>true</overwrite>
            <!-- 定义配置文件 -->
            <configurationFile>
            	src/main/resources/generatorConfig.xml
            </configurationFile>
        </configuration>
    </plugin>
</plugins>
