private FormFile picture1;

private FormFile picture2;

private FormFile picture3;
省略了get和set方法......

try {
	FormFile picture1 = gameInfoForm.getPicture1();
	gameInfo.setPictureMain(org.hibernate.Hibernate.createBlob(picture1
			.getInputStream()));

	FormFile picture2 = gameInfoForm.getPicture2();
	gameInfo.setPicture1(org.hibernate.Hibernate.createBlob(picture2
			.getInputStream()));

	FormFile picture3 = gameInfoForm.getPicture3();
	gameInfo.setPicture2(org.hibernate.Hibernate.createBlob(picture3
			.getInputStream()));
} catch (Exception e) {
	e.printStackTrace();
}
下面就是调用save等方法，保存当前的数据

将文件直接存入数据库中了.......
