1、在springmvc+mybatis项目的pom.xml文件中加如下内容，添加之后，maven会自动下载相关jar包，时间较长，需要耐心等待~~

````
<build>
    <plugins>
        <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>
    </plugins>
</build> 
````
2、创建generatorConfig.xml配置文件
````
<?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="F:\\myresource\\myprofile\\apache-maven-3.5.0\\maven-dependcies\\mysql\\mysql-connector-java\\5.1.30\\mysql-connector-java-5.1.30.jar" />  
<context id="MysqlTables" targetRuntime="MyBatis3">  
<commentGenerator>  
  
<property name="suppressAllComments" value="true" />  
</commentGenerator>  
  
<jdbcConnection driverClass="com.mysql.jdbc.Driver"  
connectionURL="jdbc:mysql://localhost:3306/sdsh" userId="root"  
password="123456">  
</jdbcConnection>  
  
<javaTypeResolver>  
<property name="forceBigDecimals" value="false" />  
</javaTypeResolver>  
  
<javaModelGenerator targetPackage="com.cn.jean.model"  
targetProject="src\\main\\java">  
  
<property name="enableSubPackages" value="true" />  
  
<property name="trimStrings" value="true" />  
</javaModelGenerator>  
<sqlMapGenerator targetPackage="com.cn.jean.dao"  
targetProject="src\\main\\java">  
<property name="enableSubPackages" value="true" />  
</sqlMapGenerator>  
<javaClientGenerator type="XMLMAPPER"  
targetPackage="com.cn.jean.dao" targetProject="src\\main\\java">  
<property name="enableSubPackages" value="true" />  
</javaClientGenerator>  
  
<table schema="dispatch" tableName="sys\_user" domainObjectName="User"  
enableCountByExample="false" enableUpdateByExample="false"  
enableDeleteByExample="false" enableSelectByExample="false"  
selectByExampleQueryId="false">  
<property name="useActualColumnNames" value="true" />  
</table>  
  
</context>  
</generatorConfiguration>
````
3、生成方式   
mvn mybatis-generator:generate   
选中pom.xml运行Run As   
截图如下：
