整合hibernate和spring這樣的文章已經(jīng)很多了,下面我們來看看如何利用myeclipse的功能為整合提速咯
1.首先,創(chuàng)建工程,可以直接選創(chuàng)建J2EE web工程
(這....就不用貼圖了吧)
2.導(dǎo)入spring, 選擇myeclipse的add spring capabilities,注意把copy .....打勾(注,如果想要在spring的配置文件中配置hibernate的話, 一定要先導(dǎo)入spring)
3. 導(dǎo)入hibernate, 選擇myeclipse的add hibernatecapabilities,注意把copy .....打勾
這時,myeclipse檢測到已有spring,會問如何處理hibernate配置信息, 這里, 我們選擇把hibernate的配置信息寫在spring的配置信息中
接著,既然選擇把在spring配置文件中配置hibernate信息,就需要設(shè)置hibernate的sessionfactory在配置文件中的bean id, 這里, 就設(shè)置為sessionFactory
然后要配置sessionFactory對應(yīng)的數(shù)據(jù)源,注,數(shù)據(jù)源對應(yīng)的bean id也需要設(shè)置,可以簡單設(shè)置為dataSource
就不貼圖咯
最后,選擇sessionfactory對于的實現(xiàn)類,可以就用spring提供的LocalSessionFactory
這樣, 我們就在項目中添加了spring和hibernate并將他們給予整合咯
3.應(yīng)用:
配置好了環(huán)境,我們當(dāng)然還得應(yīng)用咯.下面給出我的代碼
首先創(chuàng)建pojo和對應(yīng)的hbm.xml
package mapping;
public class Test {
public Test() {
super ();
// TODO Auto-generated constructor stub
}
private int id;
private String name;
public int getId() {
return id;
}
public void setId( int id) {
this .id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this .name = name;
}
}
<? xml version="1.0" ?>
<! DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
< hibernate-mapping default-lazy ="false" auto-import ="true" package ="mapping" >
< class table ="test" name ="Test" >
< id name ="id" column ="test_id" type ="int" >
< generator class ="native" ></ generator >
</ id >
< property name ="name" type ="string" column ="name" ></ property >
</ class >
</ hibernate-mapping >
然后開發(fā)對應(yīng)的DAO操作pojo, 因為我比較懶,所以直接使用HibernateTemplate進(jìn)行操作
package mapping;
import java.util.List;
import org.hibernate.Criteria;
import org.springframework.orm.hibernate3.HibernateTemplate;
public class TestDAO {
private HibernateTemplate hibernateTemplate;
public TestDAO() {
super();
// TODO Auto-generated constructor stub
}
public Test getTest(String name) throws Exception {
Test t=new Test();
t.setName(name);
List list = this.getHibernateTemplate().findByExample(t);
if (list.isEmpty())
throw new Exception("No Such Record");
else
return (Test) list.get(0);
}
public void addTest(String name) {
Test test = new Test();
test.setName(name);
this.getHibernateTemplate().save(test);
}
public void updateTest(Test test){
this.getHibernateTemplate().update(test);
}
public void deleteTest(Test test){
this.getHibernateTemplate().delete(test);
}
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate ht) {
this.hibernateTemplate = ht;
}
}
相應(yīng)的,還需要修改下spring的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/nirvana?useUnicode=true</value>
</property>
<property name="username">
<value>dyerac</value>
</property>
<property name="password">
<value></value>
</property>
</bean>
<bean id="sessoinFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="connection.characterEncoding">utf8</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="mappingDirectoryLocations">
<list >
<value>src/mapping</value>
</list>
</property>
</bean>
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory">
<ref bean="sessoinFactory"/>
</property>
<property name="allowCreate">
<value>true</value>
</property>
</bean>
<bean id="testDAO" class="mapping.TestDAO">
<property name="hibernateTemplate">
<ref bean="hibernateTemplate"/>
</property>
</bean>
</beans>
最后的最后,開發(fā)一個測試類:
import mapping.Test;
import mapping.TestDAO;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class Tester {
public static void main(String args[]) {
ApplicationContext ctx = new FileSystemXmlApplicationContext(
"src/applicationContext.xml");
TestDAO test = (TestDAO) ctx.getBean("testDAO");
//test.addTest("dyerac");
try {
Test t = test.getTest("bsbs");
System.err.println(t.getName());
//t.setName("bsbs");
//test.updateTest(t);
//test.deleteTest(t);
} catch (Exception e) {
System.err.println(e);
}
}
}
