整合Spring和Hibernate

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,  這裏, 我們選擇把hibernate的配置信息寫在spring的配置信息中

 

 

接着,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, 這裏, 就設置爲sessionFactory

 

 

然後要配置sessionFactory對應的數據源,注,數據源對應的bean id也需要設置,可以簡單設置爲dataSource
就不貼圖咯

 

 

最後,選擇sessionfactory對於的實現類,可以就用spring提供的LocalSessionFactory

 

這樣, 我們就在項目中添加了spring和hibernate並將他們給予整合咯

 

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

public class Userinfo implements java.io.Serializable { // Fields private Long userid; private String username; // Constructors /** default constructor */ public Userinfo() { } /** full constructor */ public Userinfo(String username) { this.username = username; } // Property accessors public Long getUserid() { return this.userid; } public void setUserid(Long userid) { this.userid = userid; } public String getUsername() { return this.username; } public void setUsername(String username) { this.username = username; } }

 

<hibernate-mapping> <class name="com.softfz.Userinfo" table="USERINFO" schema="SOFTFZ"> <id name="userid" type="java.lang.Long" unsaved-value="2"> <column name="USERID" precision="22" scale="0" /> <generator class="sequence"> <param name="sequence">seq_userinfo</param> </generator> </id> <property name="username" type="java.lang.String"> <column name="USERNAME" length="40" /> </property> <sql-query name="query1"> <!--[CDATA[ select u.* from userinfo u where u.userid>? ]]--> <return alias="u" class="com.softfz.Userinfo"></return> </sql-query> </class> </hibernate-mapping>

 

然後開發對應的DAO操作pojo, 因爲我比較懶,所以直接使用HibernateTemplate進行操作

public void save(){ Userinfo userinfo = new Userinfo(); userinfo.setUsername("kaka"); this.getHibernateTemplate().save(userinfo); ///同Hibernate的Session相同的操作 //this.getHibernateTemplate().update(entity); //this.getHibernateTemplate().get(Userinfo.class, 2L); //this.getHibernateTemplate().delete(entity); //this.getHibernateTemplate().load(Userinfo.class, 2L); //this.getHibernateTemplate().saveOrUpdateAll(entities) }

 

相應的,還需要修改下spring的配置文件

 

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"> </property> <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"> </property> <property name="username" value="softfz"></property> <property name="password" value="whh"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.Oracle9Dialect </prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list> <value>com/softfz/Userinfo.hbm.xml</value> </list> </property> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="userDAO" class="com.softfz.UserinfoDAO"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean> </beans>

 

最後的最後,開發一個測試類:

public class TestMain { public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); UserinfoDAO userinfoDAO = (UserinfoDAO)applicationContext.getBean("userDAO"); //userinfoDAO.saveOrUpdate(); /* Userinfo tmp = new Userinfo(); //tmp.setUserid(1L); tmp.setUsername("test"); List list=userinfoDAO.pageQuery(tmp); for (Iterator iterator = list.iterator(); iterator.hasNext();) { Userinfo userinfo = (Userinfo) iterator.next(); System.out.println(userinfo.getUsername()); }*/ //userinfoDAO.updateOrDeleteByIn(new Long[]{1l,3l,22l}); int allcount=userinfoDAO.pageQueryCount(new Userinfo("test")); System.out.println(allcount); } }
