1、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>
  <!--配置文件--->      
  <properties resource="jdbc.properties"/>
  <!--数据库jar--->
  <classPathEntry location="webapp/WEB-INF/lib/mysql-connector-java.jar" />

  <context id="context1" defaultModelType="flat" targetRuntime="MyBatis3Simple">
    <property name="javaFileEncoding" value="UTF-8"/>

    <plugin type="org.mybatis.generator.plugins.CustomerPluginAdapter">
            <property name="targetPackage"         value="com.charlin.erp.${module}.${package}.service" />
            <property name="implementationPackage" value="com.charlin.erp.${module}.${package}.service.impl" />
            <property name="controllerPackage"     value="com.charlin.erp.${module}.${package}.action" />
            <property name="controllerPath"        value="${path}" />
            <property name="targetProject"         value="${module}/src/main/java" />
            <property name="generatedSC"         value="${generatedSC}" />
    </plugin>
    <plugin type="org.mybatis.generator.plugins.ExpandPluginAdapter">

    </plugin>
    <commentGenerator>
        <property name="suppressDate" value="true"/>
        <property name="suppressAllComments" value="true" />
    </commentGenerator>

    <jdbcConnection connectionURL="${jdbc.url_main}" driverClass="${jdbc.driver}" password="${jdbc.password}" userId="${jdbc.username}" />
    <javaModelGenerator targetPackage="com.charlin.erp.${module}.${package}.model" targetProject="core/src/main/java" />
    <sqlMapGenerator targetPackage="com.charlin.erp.${module}.${package}.dao" targetProject="core/src/main/java"   />
    <javaClientGenerator targetPackage="com.charlin.erp.${module}.${package}.dao" targetProject="core/src/main/java" type="XMLMAPPER" />

  <table tableName="${tableName}"  domainObjectName="${className}" mapperName="${className}DAO"> </table>
  </context>
</generatorConfiguration>

2、运行生成

package com.charlin.erp.common.generator.run;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

import java.util.ArrayList;
import java.util.List;

public class MyBatisGeneratorRun {

    public static void main(String[] args) throws Exception {
        List<String> warnings = new ArrayList<String>();

        boolean overwrite = true;
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(MyBatisGeneratorRun.class.getResourceAsStream("./generatorConfig.xml"));
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);

        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
        System.out.println(warnings);
    }

}
