　　https://github.com/mybatis/generator/releases

2.解压并进入bin目录

3.下载mysql-connector-java-5.1.40-bin、mybatis-3.4.4至bin目录

4.新建src目录和generatorConfig.xml配置文件

22         <!-- 生成模型的包名和位置-->    
23         <javaModelGenerator targetPackage="test.domain" targetProject="src">    
24             <property name="enableSubPackages" value="true"/>    
25             <property name="trimStrings" value="true"/>    
26         </javaModelGenerator>    
27         <!-- 生成映射文件的包名和位置-->    
28         <sqlMapGenerator targetPackage="test.mapping" targetProject="src">    
29             <property name="enableSubPackages" value="true"/>    
30         </sqlMapGenerator>    
31         <!-- 生成DAO的包名和位置-->    
32         <javaClientGenerator type="XMLMAPPER" targetPackage="test.IDao" targetProject="src">    
33             <property name="enableSubPackages" value="true"/>    
34         </javaClientGenerator>    
35         <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->    
36         <table tableName="crawl_data" domainObjectName="News" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>  
37     </context>    
38 </generatorConfiguration>    

6.命令行下运行;

　　java -jar mybatis-generator-core-1.3.5.jar -configfile generatorConfig.xml -overwrite
