在maven项目中使用

1.导包，版本是1.3.2，一定要对应，不然出错了，很难找到问题，我用了1.3.6的版本，出了问题找了半天

//版本是1.3.2，一定要对应，不然出错了，很难找到问题，我用了1.3.6的版本，出了问题找了半天
<mybaits.generator.version>1.3.2</mybaits.generator.version>


<dependency>
    <groupId>org.mybatis.generator</groupId>
	<artifactId>mybatis-generator-core</artifactId>
	<version>${mybaits.generator.version}</version>
	 <scope>test</scope>
</dependency>

这是在原项目基础上建的，还需要数据库连接的jar包；

2.xml的书写

3.入口，运行他就可以

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 GeneratorMybatis {

	public static void main(String[] args) throws IOException, XMLParserException, InvalidConfigurationException, SQLException, InterruptedException {
		List<String> warnings = new ArrayList<String>();
		boolean overwrite = true;
		ConfigurationParser cp = new ConfigurationParser(warnings);
		Configuration config = cp.parseConfiguration(new File("C:\\Users\\ss\\workspace2\\project-web\\src\\test\\resource\\generator\\generator.xml"));
		DefaultShellCallback callback = new DefaultShellCallback(overwrite);
		MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
		myBatisGenerator.generate(null);
	}
}
