1、用IDEA启动ruoyi项目

2、在mysql打开数据库ry，新建表学生表tb_student，表结构如下

3、运行ruoyi，在系统工具-代码生成中导入新建表tb_student

4、修改生成配置

5、在菜单管理下新增学生管理目录

6、生成代码

-- 菜单 SQL
insert into sys_menu (menu_name, parent_id, order_num, url, menu_type, visible, perms, icon, create_by, create_time, update_by, update_time, remark)
values('学生管理', '2000', '1', '/student/student', 'C', '0', 'student:student:view', '#', 'admin', sysdate(), '', null, '学生管理菜单');

-- 按钮父菜单ID
SELECT @parentId := LAST_INSERT_ID();

-- 按钮 SQL
insert into sys_menu (menu_name, parent_id, order_num, url, menu_type, visible, perms, icon, create_by, create_time, update_by, update_time, remark)
values('学生管理查询', @parentId, '1',  '#',  'F', '0', 'student:student:list',         '#', 'admin', sysdate(), '', null, '');

insert into sys_menu (menu_name, parent_id, order_num, url, menu_type, visible, perms, icon, create_by, create_time, update_by, update_time, remark)
values('学生管理新增', @parentId, '2',  '#',  'F', '0', 'student:student:add',          '#', 'admin', sysdate(), '', null, '');

insert into sys_menu (menu_name, parent_id, order_num, url, menu_type, visible, perms, icon, create_by, create_time, update_by, update_time, remark)
values('学生管理修改', @parentId, '3',  '#',  'F', '0', 'student:student:edit',         '#', 'admin', sysdate(), '', null, '');

insert into sys_menu (menu_name, parent_id, order_num, url, menu_type, visible, perms, icon, create_by, create_time, update_by, update_time, remark)
values('学生管理删除', @parentId, '4',  '#',  'F', '0', 'student:student:remove',       '#', 'admin', sysdate(), '', null, '');

insert into sys_menu (menu_name, parent_id, order_num, url, menu_type, visible, perms, icon, create_by, create_time, update_by, update_time, remark)
values('学生管理导出', @parentId, '5',  '#',  'F', '0', 'student:student:export',       '#', 'admin', sysdate(), '', null, '');
