SSM框架單表增刪改查項目開發(fā)流程詳解
SSM框架單表增刪改查項目開發(fā)流程詳解
?
?
1.數(shù)據(jù)庫建表；
?
student.sql建表SQL：
create database school;
?
use school;
?
create table student(
? id int(11) unique key auto_increment,
? sno int(11) primary key,
? sname varchar(30),
? sex char(1),
? birth date,
? university varchar(50),
? dept varchar(50),
? major varchar(50),
? appearance varchar(10)
);
?
2. 新建maven項目，并在pom.xml文件中引入下列依賴；

3.在maven項目中建好如下圖所示目錄結(jié)構(gòu)；
?
4.在java目錄下建好下圖所示結(jié)構(gòu)；
?
5、在resources和webapp目錄下建好下圖所示結(jié)構(gòu)；
?
6.項目源碼。
