说明:
使用 spring2.5 +ibatis2.3.4+oscache2.4+struts2+oracle

建表


create table STUDENT
(
  SID   NUMBER(8) primary key not null,
  SNAME VARCHAR2(20) not null,
  MAJOR VARCHAR2(100),
  BIRTH DATE,
  SCORE NUMBER(6,2)
)

-- Create sequence 
create sequence STUDENT_SEQ
minvalue 1
maxvalue 999999999999999999999999999
start with 21
increment by 1
cache 20;
