当然最好的方法还是应该用jsp + JavaBean方式。
通过form把数据传到后台，用你对象的属性，如user对象，属性name，那就user.setName(Name)，然后session.save(user)trans.commit()session.close()就可以了有两种方法：一是标准的输出输入方式
比如新建一个磁盘文件c:\a.txt，
将键盘输入的一字符串写到文件中：
FILE *ft
char str[50]
ft=fopen("c:\\a.txt","w+")
printf("输入一个字符串：")
scanf("%s",str)
fputs(str,ft)
fclose(ft)
//重新打开这个文件并读出字符串，显示在屏幕上
ft=fopen("c:\\a.txt","rt")
fgets(str,50,ft)
fclose(ft)
printf("%s",str)
二是低级输入输出方式
仍如上例：
int hd
char str[50]
printf("输入一个字符串：")
scanf("%s",str)
hd=open("c:\\a.txt",O_CREAT|O_TEXT|O_WRONLY)
write(hd,str,strlen(str))
close(hd)
//重新打开这个文件并读出字符串，显示在屏幕上
hd=open("c:\\a.txt",O_TEXT|O_RDONLY)
read(hd,str,50)
close(hd)
printf("%s",str)
