1：依赖jar包

    <dependency>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-core</artifactId>
        <version>1.3.6</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.37</version>
    </dependency>

2：启动类

import java.io.File;  
import java.io.IOException;  
import java.sql.SQLException;  
import java.util.ArrayList;  
import java.util.List;  

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

public class MybatisGeneratorUtil {  

    public static void main(String[] args) {  
        try {  
            System.out.println("start generator ...");  
            List<String> warnings = new ArrayList<String>();  
            boolean overwrite = true;  
            File configFile = new File(MybatisGeneratorUtil.class.getResource("/generator.xml").getFile());  
            ConfigurationParser cp = new ConfigurationParser(warnings);  
            Configuration config = cp.parseConfiguration(configFile);  
            DefaultShellCallback callback = new DefaultShellCallback(overwrite);  
            MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);  
            myBatisGenerator.generate(null);  
            System.out.println("end generator!");  
        } catch (IOException e) {  
            e.printStackTrace();  
        } catch (XMLParserException e) {  
            e.printStackTrace();  
        } catch (InvalidConfigurationException e) {  
            e.printStackTrace();  
        } catch (SQLException e) {  
            e.printStackTrace();  
        } catch (InterruptedException e) {  
            e.printStackTrace();  
        }  
    }  

}

3：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="C:\Users\Administrator\.m2\repository\mysql\mysql-connector-java\5.1.37\mysql-connector-java-5.1.37.jar" />    

  <context id="Mysql2Tables" targetRuntime="MyBatis3">
  <!-- 去除注释 -->
    <commentGenerator>
        <property name="suppressDate" value="true"/>
        <property name="suppressAllComments" value="true" />
    </commentGenerator>    
    <!-- 数据库连接 -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"    
        connectionURL="jdbc:mysql://localhost:3306/test2"    
        userId="root"    
        password="root">    
    </jdbcConnection>    
    <!-- Java类型解析器 -->
    <!--
            true：使用BigDecimal对应DECIMAL和 NUMERIC数据类型
            false：默认,
               scale>0;length>18：使用BigDecimal;
               scale=0;length[10,18]：使用Long；
               scale=0;length[5,9]：使用Integer；
               scale=0;length<5：使用Short；
         -->
    <javaTypeResolver >    
      <property name="forceBigDecimals" value="false" />    
    </javaTypeResolver>    

    <!-- 保存位置并set时使用trim() -->
    <javaModelGenerator targetPackage="com.spring.entity" targetProject="src">    
      <property name="trimStrings" value="true" />    
    </javaModelGenerator>   

    <table tableName="%" enableCountByExample="false" enableUpdateByExample="false"    
           enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">    
    </table>    

  </context>    
</generatorConfiguration> 

只生成了数据库对应的实体类，并且屏蔽了的注释
