# **首先在pom文件中，添加mybatis-generator-maven-plugin** #

<groupId>org.mybatis.generator</groupId>  
        <artifactId>mybatis-generator-maven-plugin</artifactId>  
        <version>1.3.2</version>  
        <configuration>  
          <verbose>true</verbose>  
          <overwrite>true</overwrite>  
        </configuration>

</plugin>

# 然后将generatorConfig.xml拷贝到工程项目resource目录下![SouthEast][] #

# generatorConfig.xml代码如下，注解很详细看一下就会明白 #

在同级目录下创建datasource.properties文件，用来配置数据库链接，这个代码就不贴了，需要注意在resource包下需要添加链接的jar![SouthEast 1][]
