1.在pom文件中添加依赖配置

<build>

<plugins>

<plugin>

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

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

<version>1.3.7</version>

<configuration>

<configurationFile>src/main/resources/generatorConfig.xml</configurationFile>

<overwrite>true</overwrite>

<verbose>true</verbose>

</configuration>

</plugin>

</plugins>

</build>

2.新建properties文件和xml配置文件

3.properties文件存储基本信息

#文档测试平台数据库

driver=com.mysql.jdbc.Driver

icc.jdbc.url=jdbc:mysql://localhost:15381/icc?useSSL=false&autoReconnect=true&useAffectedRows=true

icc.jdbc.username=root

icc.jdbc.password=xx-mysql-xx

#entity 包名和 java目录

modelPackage=dataobject

modelProject=src/main/java

#sqlmap包名 和resources目录

sqlPackage=mapper

sqlProject=src/main/java

#mapper包名和 java目录

mapperPackage=mapper

mapperProject=src/main/java

table=icc_config

4.xml文件中存放转换数据的信息

<?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>
    <!--导入属性配置 -->
    <properties resource="dal.properties"/>
    <!-- 把路径换成自己的 -->
    <classPathEntry
            location=".m2/repository/mysql/mysql-connector-java/5.1.25/mysql-connector-java-5.1.25.jar" />
    <context id="context1">
        <!-- 注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true" /><!-- 是否取消注释 -->
            <property name="suppressDate" value="true" /> <!-- 是否生成注释代时间戳 -->
        </commentGenerator>

        <jdbcConnection driverClass="${driver}"
                        connectionURL="${icc.jdbc.url}"
                        userId="${icc.jdbc.username}"
                        password="${icc.jdbc.password}" />

        <!-- 类型转换 -->
        <javaTypeResolver>
            <!-- 是否使用bigDecimal， false可自动转化以下类型（Long, Integer, Short, etc.） -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <javaModelGenerator targetPackage="${modelPackage}"
                            targetProject="${modelProject}" />
        <sqlMapGenerator targetPackage="${sqlPackage}" targetProject="${sqlProject}" />
        <javaClientGenerator targetPackage="${mapperPackage}"
                             targetProject="${mapperProject}" type="XMLMAPPER" />
        <!-- 如果需要通配所有表 直接用sql的通配符    %即可 -->
        <table schema="" tableName="${table}" enableCountByExample="false"
               enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false"

        >
            <!--<columnOverride column="REMARKS" javaType="java.lang.String" jdbcType="VARCHAR"/>-->
        </table>

    </context>
</generatorConfiguration>

5.点击maven：Plugins->mybatis-generator,双击mybatis-generator:generator即可。如果没有这个插件，刷新试试.
