1、pom文件中build中添加plugin；

            <!--mybatis 逆向工程-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <configuration>
                    <!--指定逆向配置文件-->
                    <configurationFile>src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.44</version>
                    </dependency>
                    <dependency>
                        <groupId>com.itfsw</groupId>
                        <artifactId>mybatis-generator-plugin</artifactId>
                        <version>1.0.5</version>
                    </dependency>
                </dependencies>
            </plugin>

2、配置文件——generatorConfig.xml；

<?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>

    <context id="mybatis-generate" targetRuntime="MyBatis3">

        <property name="" value=""/>
        <plugin type="org.mybatis.generator.plugins.RowBoundsPlugin"></plugin><!--分页用-->
        <plugin type="com.itfsw.mybatis.generator.plugins.BatchInsertPlugin"/>
        <commentGenerator>
            <property name="addRemarkComments" value="true"/>
        </commentGenerator>
                    <!--数据库连接信息-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/redis_test?characterEncoding=utf8"
                        userId="root"
                        password="12321">
        </jdbcConnection>
                    <!--逆向工程文件输出位置配置-->
        <!--实体类-->
        <javaModelGenerator targetPackage="com.fc.redis.entity" targetProject="src/main/java">
        </javaModelGenerator>
        <!--mapper.xml文件位置-->
        <sqlMapGenerator targetPackage="com.fc.redis.mapper" targetProject="src/main/resources">
        </sqlMapGenerator>
        <!--mapper接口-->
        <javaClientGenerator type="MIXEDMAPPER" targetPackage="com.fc.redis.mapper" targetProject="src/main/java">
        </javaClientGenerator>

        <!--需要mybatis生成的表放在这里-->
        <!-- <table tableName="tb_product_island">
            <generatedKey column="id" sqlStatement="MySql"
                identity="true" />
        </table> -->
        <!-- <table tableName="tb_product_visa_menu">
            <generatedKey column="visa_menu_id" sqlStatement="MySql" identity="true"/>
            <columnOverride column="employe" jdbcType="VARCHAR" />
        </table> -->
        <!--选择表，指定主键-->
        <table tableName="tb_user">
            <generatedKey column="id" sqlStatement="MySql" identity="true"/>
        </table>
    </context>

</generatorConfiguration>

3、Run Maven Build逆向生产Java代码及xml sql 文件；
