大数据Vue项目案例总结
在本月我们学习了Vue的基础知识，结合所学的内容，做了一个小的项目健康管理系统，开发所含的需求,检查项或检查组的增删改查，导入导出，缓存数据用定时任务删除，以及柱状图和柱状图，若本文对你有所帮助，建议一键三连。
创建maven项目模块，导入相关的jar包以及依赖。
，
建表建库：
create table kew(
id int primary key auto_increment,
kid varchar(20),
name varchar(20),
shi varchar(20),
xing varchar(20),
xue varchar(20),
ming varchar(20)
)
create table studentw(
id int primary key auto_increment,
sid varchar(20),
name varchar(20),
sex varchar(20),
age int,
address varchar(20),
zhu varchar(20)
)
create table zhongjian(
s_id int,
k_id int,
foreign key (s_id) references studentw (id),
foreign key (k_id) references kew (id)
)
insert into studentw (id, sid, name, sex, age, address, zhu)
values
(1,'100','小明','男',21,'河南','优秀'),
(2,'101','小红','男',21,'南阳','低级'),
(3,'102','小黑','男',41,'内乡','H欧'),
(4,'103','小有','女',11,'河南','优秀');
insert into kew (id, kid, name, shi, xing, xue, ming)
values
(1,'200','大数据','10','理科','500','理科据就是好'),
(2,'201','语文','10','文科','500','大就是好'),
(3,'202','英语','11','文科','100','大就是好'),
(4,'203','数学','22','理科','900','大就是好'),
(5,'204','政治','13','文科','100','大就是好');
insert into zhongjian (s_id, k_id)
values
(1,1),
(2,2),
(3,3),
(4,1),
(1,1);创建对应的实体类：
public class Student implements Serializable {
private Integer id;
private String sid;
private String name;
private String sex;
private Integer age;
private String address;
private String zhu;
private String names;
private List k;
提供get和set方法
} public class Ke implements Serializable {
private Integer id;
private String kid;
private String name;
private String shi;
private String xing;
private String xue;
private String ming;
