package com.model;
?
import java.sql.Date;
?
public class Person {
private Integer id;
//最好用Integer而不是用int,后面查询需要Integer
private String username;
private String password;
private Integer age;
private Date registerDate;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
?
public Date getRegisterDate() {
return registerDate;
}
public void setRegisterDate(Date registerDate) {
this.registerDate = registerDate;
}
}
5、配置Model与数据库字段的映射，在src目录下添加Person.hbm.xml(不是严格要求的):
