        <include>**/*.properties</include>
        <include>**/*.xml</include>
      </includes>
      <filtering>false</filtering>
    </resource>
    <resource>
      <directory>src/main/resources</directory>
      <includes>
        <include>**/*.properties</include>
        <include>**/*.xml</include>
      </includes>
      <filtering>false</filtering>
    </resource>
  </resources>
</build>
3，web和resources/config准备好:
 注意更改路径和数据库数据
4，要生成了哦，创建测试类Test1

public static void main(String[] args) throws Exception{

    List<String> warnings = new ArrayList<String>();
    boolean overwrite = true;//加载上面的配置文件
    File configFile = new File("./src/main/resources/config/generatorconfig.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);
}
（当然，网上其他的加注解@Test的也没错，都一样，把自动生成的的mapper和bean复制，注意路径和同级问题(●ˇ∀ˇ●)）
