编写第一个Hibernate例子
第二步：创建持久化类（持久化类的设计原则要遵循javabeans的设计原则）
javabeans的设计原则：
1.公有的类
2.提供公有的不带参数的默认的构造方法
3.属性私有
4.属性setter/getter封装
新建一个Students类（持久化类）
import java.util.Date;//学生类public class Students {// 1.公有的类// 2.提供公有的不带参数的默认的构造方法// 3.属性私有// 4.属性setter/getter封装private int sid;// 学号private String sname;// 姓名private String gender;// 性别private Date birthday;// 出生日期private String address;// 地址public Students() {}public Students(int sid, String sname, String gender, Date birthday,String address) {// super();this.sid = sid;this.sname = sname;this.gender = gender;this.birthday = birthday;this.address = address;}public int getSid() {return sid;}public void setSid(int sid) {this.sid = sid;}public String getSname() {return sname;}public void setSname(String sname) {this.sname = sname;}public String getGender() {return gender;}public void setGender(String gender) {this.gender = gender;}public Date getBirthday() {return birthday;}public void setBirthday(Date birthday) {this.birthday = birthday;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}@Overridepublic String toString() {return "Students [sid=" + sid + ", sname=" + sname + ", gender="+ gender + ", birthday=" + birthday + ", address=" + address+ "]";}}Hibernate初探之单表映射——创建持久化类
