spring+hibernate,数据库插入图片
主要就三個地方需要配置:
<一>hbm中,
<property name="photo1" type="binary"> <column name="photo1" not-null="false" /></property>
<二>javabean中,
private byte[] photo1 ;public void setPhoto1(byte[] photo1) {this.photo1 = photo1;}public byte[] getPhoto1() {return photo1;}
?<三>spring的applicationContext.xml中,
<!--声明一个处理句柄 Blob--> <bean id="lobHandler" lazy-init="true" />?
這樣再加上把File转成byte[]的方法,就ok了
//傳入的File 轉成byte[]public byte[] inputToByte( File f ){try {FileInputStream fis = new FileInputStream( f );byte[] buffer = new byte[1024]; int read; ByteArrayOutputStream byteArray = new ByteArrayOutputStream(); while((read = fis.read(buffer))>0) { byteArray.write(buffer,0,read); byteArray.flush(); } byte[] bt = byteArray.toByteArray();byteArray.close();return bt ;} catch (FileNotFoundException e) {e.printStackTrace();return null;} catch (IOException e) {e.printStackTrace();return null;}}?
