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" ?>

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
