Juint下保存图片可行，但页面上操作就报错？
public void testSave() throws Exception { CardinfoServices cinfoSer = new CardinfoServices(); UserinfoServices uinfoSer = new UserinfoServices(); Userinfo userinfo = uinfoSer.findById("200"); CardownerinfoSevices oinfoSer = new CardownerinfoSevices(); Cardownerinfo oinfo = oinfoSer.findById(new Long(15)); Cardinfo cardinfo = new Cardinfo(); cardinfo.setCardid(new Long(51)); // 主键 cardinfo.setCardname("Hello"); cardinfo.setCardownerinfo(oinfo); cardinfo.setUserinfo(userinfo); cardinfo.setPhonenum("13800000000"); // 插入图片 FileInputStream ff = new FileInputStream("D:\\jdk.bmp"); Blob img = Hibernate.createBlob(ff); cardinfo.setCardimage(img); boolean cinfoSave = cinfoSer.save(cardinfo); if (cinfoSave) { System.out.println("增加成功"); } else { System.out.println("增加错误"); } }
