更新Java图形界面的表格里更新数据后,怎样更新数据库里的信息?

请问你是用jsp显示swing显示。jsp显示就会人性化一点

用数据库用oracle。首先你要建立用户信息你才可以更好的查询

table tbStu的建立

create table STUINFO

(

STU_ID NUMBER not null,

STU_NUMBER VARCHAR2(8) not null,

STU_NAME VARCHAR2(20) not null,

STU_AGE NUMBER,

STU_SEX CHAR(2) default '男',

STU_CARD VARCHAR2(18) not null,

STU_JOINTIME DATE,

STU_ADDRESS VARCHAR2(200) default '地址不详'

)

//你可以插入你想要的数据

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (5, '005', '溺水的鱼', null, '女', '430101198203050928', to_date('04-12-2006', 'dd-mm-yyyy'), '长沙市六堆子')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (6, '006', '皮蛋超人', 26, '男', '430108198308041108', to_date('01-09-2006', 'dd-mm-yyyy'), '长沙市南门口')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (7, '007', '樱桃肉丸子', null, '女', '430103198904058801', to_date('06-12-2006', 'dd-mm-yyyy'), '长沙市五一广场')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (1, '001', '小李飞车', 21, '男', '430105198503058982', to_date('06-12-2006', 'dd-mm-yyyy'), '长沙市金盆岭')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (2, '002', '一了百了', 25, '男', '430208197903051263', to_date('05-01-2006', 'dd-mm-yyyy'), '长沙市望月湖')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (33, '008', '李寻欢', 36, '男', '430103198103052927', to_date('13-11-2010 10:12:56', 'dd-mm-yyyy hh24:mi:ss'), '地址不详')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (3, '003', '路过莫错过', 20, '男', '430103198103052928', to_date('06-11-2005', 'dd-mm-yyyy'), '浏阳市')

insert into STUINFO (STU_ID, STU_NUMBER, STU_NAME, STU_AGE, STU_SEX, STU_CARD, STU_JOINTIME, STU_ADDRESS)

values (4, '004', '过来瞧瞧', 22, '男', '430106198503052452', to_date('02-03-2007', 'dd-mm-yyyy'), '长沙市马王堆')

至此数据库已经建立好了

接下来是写一个java beanjava daoservlet , jsp.

太多了。如果觉得可以。。你给个邮箱号码给我咯。我直接发给你咯

这个问题我也碰到过，你更新数据库后，调用方法立即把DefaultTableModel跟数据库数据再次吻合，然后再后面加上JTable名.repaint()方法就可以了，它会立即自动刷新表格同步。（如这样声明的：JTable myTable=new JTable(你的Table模型)然后更新数据库后，更改DefaultTableModel与数据库数据一样，再在它之后调用语句myTable.repaint()就可以了

如果只是这样的效果,直接刷新JPanel(JPanel.repaint()),不是刷新JScrollPane.

同时要注意CommonalityClass.createGainTable(2) 函数里的JTable要清除掉原有的数据,再加入新数据.有或者建立个新的JTable.
