文件结构
注意，这里我将generatorConfig.xml文件放到了src目录下，即：与main在同级目录
配置信息
pom.xml文件内容：主要功能是导入jar包--一般需要3个jar包：
| 数据库连接jar包 |
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.9</version> </dependency> |
| Mybatis包 |
<dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> |
| Mybatis generator core 包 |
<dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> |
| pom.xml 内容汇总 |

generatorConfig.xml文件内容：
其中标红的需要着重修改
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

Test.java 文件内容：
注意generatorConfig.xml文件的路径
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.io.File;
import java.util.ArrayList;
import java.util.List;
public class Test {
public static void main(String[] args) throws Exception {
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("src/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);
}
}

最后就是运行一下Test文件，大功告成！
