spring+hibernate的配置

第一种方式：

hiberante.cfg.xml配置如下：

<!DOCTYPE hibernate-configuration PUBLIC
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory>
  <property name="hibernate.hbm2ddl.auto">update</property>
  <property name="hibernate.dialect">
   org.hibernate.dialect.MySQLDialect
  </property>
  <property name="hibernate.show_sql">true</property>
  <mapping resource="com/oristand/hibernate/pojo/User.hbm.xml" />
 </session-factory>
</hibernate-configuration>

 接着配置applicationContext-hibernate.xml

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
 <bean id="dataSource"
  class="org.springframework.jdbc.datasource.DriverManagerDataSource">
  <property name="driverClassName">
   <value>com.mysql.jdbc.Driver</value>
  </property>
  <property name="url">
   <value>jdbc:mysql://localhost:3306/ssh</value>
  </property>
  <property name="username">
   <value>root</value>
  </property>
  <property name="password">
   <value>123456</value>
  </property>
 </bean>

 <bean id="sessionFactory"
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="dataSource">
   <ref local="dataSource" />
  </property>
  <property name="configLocation">
       <value>classpath:hibernate.cfg.xml</value>
  </property>

 </bean>
</beans>

 第二种方式，不要hiberante.cft.xml，直接配置；

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:context="http://www.springframework.org/schema/context"
        xsi:schemaLocation="http://www.springframework.org/schema/beans         
         http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
         http://www.springframework.org/schema/context 
         http://www.springframework.org/schema/context/spring-context-2.5.xsd
          http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-2.5.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
       http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd">
        <context:property-placeholder location="db.properties"></context:property-placeholder>
        <context:annotation-config />
        <bean name="dataSource"
                class="org.springframework.jdbc.datasource.DriverManagerDataSource">
                <property name="driverClassName" value="${driverClassName}" ></property>
                <property name="url" value="${url}" />
                <property name="username" value="${username}" />
                <property name="password" value="${password}" />
        </bean>
        <bean name="sessionFactory"
                class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
                <property name="dataSource" ref="dataSource" />
                <property name="hibernateProperties">
                        <props>
                                <prop key="hibernate.dialect">
                                        org.hibernate.dialect.MySQLDialect
                                </prop>
                                <prop key="hibernate.show_sql">true</prop>
                                <prop key="hibernate.hbm2ddl.auto">create-drop</prop>
                        </props>
                </property>
                <property name="mappingResources">
                        <list>
                                <value>cn/iceway/entity/myuser.hbm.xml</value>
                        </list>
                </property>
        </bean>
        <bean name="baseHibernateDAO" class="cn.iceway.BaseHibernateDAO">
                <property name="sessionFactory" ref="sessionFactory"></property>
        </bean>
</beans>

 倘若实体类使用了annotation，则需要对sessionFacotory做写改动：

      <bean name="sessionFactory"
                class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
                <property name="dataSource" ref="dataSource"></property>
                <property name="hibernateProperties">
                        <props>
                                <prop key="hibernate.dialect">
                                        org.hibernate.dialect.MySQLDialect
                                </prop>
                                <prop key="hibernate.show_sql">true</prop>
                                <prop key="hibernate.hbm2ddl.auto">create</prop>
                        </props>
                </property>
                <property name="packagesToScan">  //指明查找的annotated class路径，User类的路径为cn.iceway.entity.User
                <value>cn.iceway.entity</value>
                </property>
        </bean>
