	boolean overwrite = true;
//	指定配置文件
	File configFile = new File("C:\\Users\\Administrator\\eclipse-workspace\\Study\\src\\main\\resources\\config.xml");

	Configuration configuration = null;
	MyBatisGenerator myBatisGenerator = null;
	try {
		configuration = configurationParser.parseConfiguration(configFile);
		DefaultShellCallback callback = new DefaultShellCallback(overwrite);
		myBatisGenerator = new MyBatisGenerator(configuration, callback, waList);
		myBatisGenerator.generate(null);
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	} catch (XMLParserException e) {
		// TODO Auto-generated catch block

	} catch (InvalidConfigurationException e) {

	} catch (SQLException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	} catch (InterruptedException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	
}
//执行main方法生成代码，实体类等
	public static void main(String[] args) {
		
		MybatisGenTest mybatisGenTest = new MybatisGenTest();
		mybatisGenTest.generator();
		
	}
}

已解决，问题在log4j.xml配置文件结尾少了 </log4j:configuration>
新问题：
og4j: reset attribute= "false".
log4j: Threshold ="null".
log4j:WARN No appenders could be found for logger (org.mybatis.generator.internal.db.DatabaseIntrospector).
log4j:WARN Please initialize the log4j system properly.
