最简单的SSM整合实战(IDEA版本的)
非常感谢16级五班刘雨 ,16软工4班的吴天赋 协助整理
项目完整的目录结构
数据库准备
CREATE TABLE customer(
id int(32) PRIMARY key AUTO_INCREMENT,
username varchar(50),
jobs varchar(50),
phone varchar(16)
);
接下来自己随意插入几条记录即可

03 Customer.java

* 客户持久化类
*/
public class Customer {
private Integer id; // 主键id
private String username; // 客户名称

private String phone; // 电话
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getJobs() {
return jobs;
}
public void setJobs(String jobs) {

}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
}
