【Oracle】springboot连接Oracle 集成mybatis、druid

基于spring-boot 2.7.11，连接Oracle 11g
仅做一个简单的示例

特别说明（不一定正确，还请指正）：我Oracle也不熟，但据我观察发现，springboot项目配置Oracle驱动之后，就不需要Oracle的客户端instantclient，以及后面将该项目打成jar包部署的同时，linux环境中也不需要进行instantclient相关的配置。

项目结构与库表数据

-- 创建表: student_info 属主: scott (默认当前用户)
create table scott.student_info (
  sno         number(10) constraint pk_si_sno primary key,
  sname       varchar2(10),
  sex         varchar2(2),
  create_date date
);
-- 添加注释
comment on table scott.student_info is '学生信息表';
comment on column scott.student_info.sno is '学号';
comment on column scott.student_info.sname is '姓名';
comment on column scott.student_info.sex is '性别';
comment on column scott.student_info.create_date is '创建日期';

-- 插入
insert into scott.student_info (sno, sname, sex, create_date)
values (1, '张三', '男', sysdate);
insert into scott.student_info (sno, sname, sex, create_date)
values (2, '李四', '女', sysdate);
insert into scott.student_info (sno, sname, sex, create_date)
values (3, '王五', '男', sysdate);
commit;
select * from scott.student_info;
