因为整合spring和hibernate所以，需要用到spring里面复写Hibernate的类以有DI和IOC特性
db.sql
hibernate_basic数据库
表 person
字段
pid pname psex
Person.java
1 package cn.edu.spring_hibernate; 2 3 public class Person { 4 private Long pid; 5 private String pname; 6 private String psex; 7 public Long getPid() { 8 return pid; 9 } 10 public void setPid(Long pid) { 11 this.pid = pid; 12 } 13 public String getPname() { 14 return pname; 15 } 16 public void setPname(String pname) { 17 this.pname = pname; 18 } 19 public String getPsex() { 20 return psex; 21 } 22 public void setPsex(String psex) { 23 this.psex = psex; 24 } 25 26 }
Person.hbm.xml
1 <?xml version="1.0" encoding="utf-8"?> 2 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 3 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 4 <hibernate-mapping> 5 <!-- 6 用来描述一个持久化类 7 name 类的全名 8 table 可以不写 默认值和类名一样 9 catalog 数据库的名称 一般不写 10 --> 11 <class name="cn.edu.spring_hibernate.Person"> 12 <!-- 13 标示属性 和数据库中的主键对应 14 name 属性的名称 15 column 列的名称 16 --> 17 <id name="pid" column="pid" length="200" type="java.lang.Long"> 18 <!-- 19 主键的产生器 20 就该告诉hibernate容器用什么样的方式产生主键 21 --> 22 <generator class="increment"></generator> 23 </id> 24 <!-- 25 描述一般属性 26 --> 27 <property name="pname" column="pname" length="20" type="string"> 28 </property> 29 30 <property name="psex" column="psex" length="10" type="java.lang.String"></property> 31 </class> 32 </hibernate-mapping>
PersonDao.java
1 package cn.edu.spring_hibernate; 2 public interface PersonDao { 3 public void savePerson(Person person); 4 }
PersonDaoImpl.java
1 package cn.edu.spring_hibernate; 2 import org.springframework.orm.hibernate3.support.HibernateDaoSupport; 3 //继承HibernateDaoSupport操作数据库，事务管理在配置文件中配，和这个类没关系 4 public class PersonDaoImpl extends HibernateDaoSupport implements PersonDao { 5 @Override 6 public void savePerson(Person person) { 7 this.getHibernateTemplate().save(person); 8 } 9 }
PersonService.java
1 package cn.edu.spring_hibernate; 2 public interface PersonService { 3 public void savePerson(Person person); 4 }
PersonServiceImple.java
1 package cn.edu.spring_hibernate; 2 public class PersonServiceImpl implements PersonService { 3 //这里要写依赖注入，配置文件中可以配置 4 private PersonDao personDao=new PersonDaoImpl(); 5 public PersonDao getPersonDao() { 6 return personDao; 7 } 8 public void setPersonDao(PersonDao personDao) { 9 this.personDao = personDao; 10 } 11 @Override 12 public void savePerson(Person person) { 13 personDao.savePerson(person); 14 } 15 }
MyException.java（用于异常处理）
1 package cn.edu.spring_hibernate; 2 public class MyException { 3 public void defineException(Throwable ex){ 4 System.out.println(ex.getMessage()); 5 } 6 }
test.java
1 package cn.edu.spring_hibernate; 2 import org.junit.Test; 3 import org.springframework.context.ApplicationContext; 4 import org.springframework.context.support.ClassPathXmlApplicationContext; 5 public class test { 6 @Test 7 public void testSpring_Hibernate() 8 { 9 ApplicationContext context=new ClassPathXmlApplicationContext("cn/edu/spring_hibernate/config/applicationContext-spring_hibernate.xml"); 10 //这里如果 getBean("personDao")会加入数据不成功，因为配置文件中没有对其开启事务处理 11 PersonService personService=(PersonService)context.getBean("personService"); 12 Person person=new Person(); 13 person.setPname("ssss"); 14 person.setPsex("god"); 15 personService.savePerson(person); 16 } 17 }
配置文件中
hibernate.cfg.xml （配置文件中第二种配置sessionFactory的时候用到）这种方法方便点
1 <?xml version='1.0' encoding='utf-8'?> 2 <!DOCTYPE hibernate-configuration PUBLIC 3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 4 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> 5 <hibernate-configuration> 6 <!-- 7 一个session-factory只能连接一个数据库 8 --> 9 <session-factory> 10 <!-- 11 数据库的用户名 12 --> 13 <property name="connection.username">root</property> 14 <!-- 15 密码 16 --> 17 <property name="connection.password">friends</property> 18 <!-- 19 url 20 --> 21 <property name="connection.url"> 22 jdbc:mysql://localhost:3306/hibernate_basic 23 </property> 24 25 <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> 26 <!-- 27 作用：根据持久化类和映射文件生成表 28 validate 29 create-drop 30 create 31 update 32 --> 33 <property name="hbm2ddl.auto">update</property> 34 <!-- 35 显示hibernate内部生成的sql语句 36 --> 37 <property name="show_sql">true</property> 38 <mapping resource="cn/edu/spring_hibernate/Person.hbm.xml" /> 39 40 </session-factory> 41 </hibernate-configuration>
jdbc.properties (配置文件中第一种配置sessionFactory的时候用到)
1 jdbc.driverClassName=com.mysql.jdbc.Driver 2 jdbc.url=jdbc:mysql://localhost:3306/hibernate_basic 3 jdbc.username=root 4 jdbc.password=friends
