1.在项目的配置文件中放入配置文件mybatis-generator-config.xml   根据情况修改下配置

<?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>

    <!-- !!!! Driver Class Path !!!! -->

    <classPathEntry location="/Users/dongjunjie/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar"/>

    <context id="context" targetRuntime="MyBatis3">

        <plugin type="org.mybatis.generator.plugins.CaseInsensitiveLikePlugin" />

        <commentGenerator>

            <property name="suppressAllComments" value="true"/>

            <property name="suppressDate" value="true"/>

        </commentGenerator>

        <!-- !!!! Database Configurations !!!! -->

        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://****/exchange?characterEncoding=utf-8"

                        userId="exchange" password="****"/>

        <javaTypeResolver>

            <property name="forceBigDecimals" value="false"/> </javaTypeResolver>

        <!-- !!!! Model Configurations !!!! -->

        <javaModelGenerator targetPackage="com.cmcm.finance.wallet.sync.entity" targetProject="/Users/dongjunjie/IdeaProjects/wallet-sync/src/main/java">

            <property name="enableSubPackages" value="true"/>

            <property name="trimStrings" value="true"/>

        </javaModelGenerator>

        <!-- !!!! Mapper XML Configurations !!!! -->

        <sqlMapGenerator targetPackage="sqlmapper" targetProject="/Users/dongjunjie/IdeaProjects/wallet-sync/src/main/java/com/*/finance/wallet/sync/dao">

            <property name="enableSubPackages" value="true"/>

        </sqlMapGenerator>

        <!-- !!!! Mapper Interface Configurations !!!! -->

        <javaClientGenerator targetPackage="com.*.finance.wallet.sync.dao" targetProject="/Users/dongjunjie/IdeaProjects/wallet-sync/src/main/java" type="XMLMAPPER">

            <property name="enableSubPackages" value="true"/>

        </javaClientGenerator>

        <!-- !!!! Table Configurations !!!! -->

        <table tableName="distribute_coin_detail" domainObjectName="DistributeCoinDetail" enableCountByExample="true" enableDeleteByExample="true" enableSelectByExample="true"

               enableUpdateByExample="true"/>

    </context>

</generatorConfiguration>

2. 添加maven 任务

Edit-Configurations ->name  、work directory、Command line （mybatis-generator:generate -e ）

3. pom 文件中添加 build  -plugin

 <plugin>

                <groupId>org.mybatis.generator</groupId>

                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <version>1.3.2</version>

                <configuration>

                    <configurationFile>src/main/resources/dev/mybatis-generator-config.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>

4. 运行maven的自动生成插件

run-config 》 mybatis-gen -》右键 run

pom中添加Plugins 也可以在idea的maven project中 的Plugins中找到mybatis-generater 右键运行即可
