整合hibernate和spring這樣的文章已經很多了,下面我們來看看如何利用myeclipse的功能為整合提速咯
1.首先,創建工程,可以直接選創建J2EE web工程
?? (這....就不用貼圖了吧)
2.導入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, 一定要先導入spring)
3. 導入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,就需要設置hibernate的sessionfactory在配置文件中的bean id, 這里, 就設置為sessionFactory
然后要配置sessionFactory對應的數據源,注,數據源對應的bean id也需要設置,可以簡單設置為dataSource
就不貼圖咯
最后,選擇sessionfactory對于的實現類,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.應用:
? 配置好了環境,我們當然還得應用咯.下面給出我的代碼
首先創建pojo和對應的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"
?>

然后開發對應的DAO操作pojo, 因為我比較懶,所以直接使用HibernateTemplate進行操作
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);
????????}
????}
}
