Hibernate中的基礎(chǔ)配置

1、Hibernate中的基礎(chǔ)配置1 默認(rèn)情況下Hibernate會找和注解為Entity的類名相同的表名,也可以另外指定表,應(yīng)該使用注解Table,注意應(yīng)使用import javax.persistence.Table;的Table(JPA標(biāo)準(zhǔn))源代碼package com.myj.hibernate.model;import javax.persistence.Entity;import javax.persistence.Id;import javax.persistence.Table;import com.myj.hibernate.service.Test;EntityTable(na

2、me="_teacher")public class Teacher private int id;private String name;private int age;public Teacher() Idpublic int getId()    return id;public void setId(int id)    this.id = id;public String getName()    return name;public void setName(String name)  

3、60; = name;public int getAge()    return age;public void setAge(int age)    this.age = age;2 字段名和屬性名不同時(shí)源代碼package com.myj.hibernate.model;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.Id;import javax.persistence.Table;import co

4、m.myj.hibernate.service.Test;EntityTable(name="_teacher")public class Teacher private int id;private String name;private int age;public Teacher() Idpublic int getId()    return id;public void setId(int id)    this.id = id;Column(name="_name")public String getN

5、ame()    return name;public void setName(String name)    = name;public int getAge()    return age;public void setAge(int age)    this.age = age;3 屬性名不需要持久化時(shí)源代碼package com.myj.hibernate.model;import javax.persistence.Column;import javax.persistence.En

6、tity;import javax.persistence.Id;import javax.persistence.Table;import javax.persistence.Transient;import com.myj.hibernate.service.Test;EntityTable(name="_teacher")public class Teacher private int id;private String name;private int age;private String yourWifeName;public Teacher() Idpublic

7、 int getId()    return id;public void setId(int id)    this.id = id;Column(name="_name")public String getName()    return name;public void setName(String name)    = name;public int getAge()    return age;public void setAge(int age

8、)    this.age = age;Transientpublic String getYourWifeName()    return yourWifeName;public void setYourWifeName(String yourWifeName)    this.yourWifeName = yourWifeName;4 持久化日期和時(shí)間.可以使用Temporal注解來調(diào)整精度,例如Temporal(TemporalType.TIME)只顯示時(shí)間.源代碼/hibernate_001/src/com/myj/hiber

9、nate/model/Teacher.javapackage com.myj.hibernate.model;import java.util.Date;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.Id;import javax.persistence.Table;import javax.persistence.Transient;EntityTable(name="_teacher")public class Teacher privat

11、setName(String name)    = name;public int getAge()    return age;public void setAge(int age)    this.age = age;Transientpublic String getYourWifeName()    return yourWifeName;public void setYourWifeName(String yourWifeName)    this.yourWife

12、Name = yourWifeName;public Date getBirthDate()    return birthDate;public void setBirthDate(Date birthDate)    this.birthDate = birthDate;/hibernate_001/src/com/myj/hibernate/model/Teacher.javapackage com.myj.hibernate.service;import java.util.Date;import org.hibernate.Session;im

13、port com.myj.hibernate.model.Teacher;public class Test public static void main(String args)      Test test = new Test();     Teacher teacher = new Teacher();   teacher.setId(2);   teacher.setName("apple");   teacher.setA

14、ge(23);  teacher.setBirthDate(new Date();     test.createAndStoreEvent(teacher);   HibernateUtil.getSessionFactory().close();private void createAndStoreEvent(Teacher teacher)    Session session = HibernateUtil.getSessionFactory().openSession(); 

15、  session.beginTransaction();   session.save(teacher);   session.getTransaction().commit();5 使用annotation中的Enumerated(EnumType.STRING)來定義枚舉類源程序/hibernate_001/src/com/myj/hibernate/model/Teacher.javapackage com.myj.hibernate.model;import java.util.Date;import javax.persistenc
