JUnit測試：

@Test

public void testWriteBlob() throws Exception{

Students s = new Students(1,"張三豐","男",new Date(),"武當山");

//先獲得照片文件,File.separator是文件分隔符\

File f = new File("g:"+File.separator+"TheMachineHeraldViktor.jpg");

//獲得照片文件的輸入流?，字節(jié)流用inputstream？

InputStream input = new FileInputStream(f);

//創(chuàng)建Blob對象，createBlob第一個參數表示從哪個輸入流讀取，第二個參數表示讀取的長度（輸入流可用字節(jié)數）

Blob image = Hibernate.getLobCreator(session).createBlob(input,input.available());

//設置照片屬性

s.setPicture(image);

//保存到學生

session.save(s);
