1、添加jar包

<dependency>

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

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

<version>1.3.5</version>

</dependency>

2、mbg.xml文件

3、生成mapper.xml，bean，mapper文件对应的接口

public static void main(String[] args) throws Exception {        List
     
       warnings = new ArrayList
      
       ();        boolean overwrite = true;        File configFile = new File("mbg.xml");        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);    }
