1.首先创建一个maven项目；

2.在pom的build标签下配置<plugin>，注意要将插件配置放在和pluginManagement标签同级下，否则可能配置失败；

下面是插件配置：

<plugins>
    <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
            <!--配置文件的位置-->
            <configurationFile>src/main/resources/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>1.3.2</version>
            </dependency>
        </dependencies>
    </plugin>
</plugins>

3.配置generatorConfig.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC
"-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
 "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration>
   <classPathEntry
      location="D:\tool\mybatis-generator-core-1.3.2\lib\mysql-connector-java-5.1.25-bin.jar" />
   <context id="context1" targetRuntime="MyBatis3">
      <commentGenerator>
         <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
         <property name="suppressAllComments" value="true" />
         <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
      </commentGenerator>
      <jdbcConnection driverClass="com.mysql.jdbc.Driver"
         connectionURL="jdbc:mysql://ip/base" userId="root" password="root">
      </jdbcConnection>
         <!--modle路径-->
      <javaModelGenerator targetPackage="com.zhy.domain"
         targetProject="E:\ideaworkspace\Demo\src\main\java" />
         <!--xml文件生成路径-->
      <sqlMapGenerator targetPackage="mapper"
         targetProject="E:\ideaworkspace\Demo\src\main\resources" />
         <!--mapper接口文件生成路径-->
      <javaClientGenerator targetPackage="com.zhy.repository"
         targetProject="E:\ideaworkspace\Demo\src\main\java" type="XMLMAPPER" />
      <!-- shema 数据库 tableName表明 -->
      <table tableName="table" schema="base" />
    </context>
  </generatorConfiguration>

4.刷新一下maven插件，如下图所示,然后双击插件就可以自动生成代码
