1 普通jdbc方式，基本代码如下

</bean>

</property>
<property name="hibernateProperties">

<tx:method name="add*" propagation="REQUIRED" isolation="REPEATABLE_READ" />
<tx:method name="delete*" propagation="REQUIRED" isolation="REPEATABLE_READ"/>
</tx:attributes>
</tx:advice>
</beans>
上面hibernateProperties还可以这么配置，效果是一样的
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.SQLServerDialect
hibernate.show_sql=true
hiberante.format_sql=true
</value>
</property>
还可以直接把配置信息放到hibernate.cfg.xml中，代码如下
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="configLocations">
<list>
<value>classpath:hibernate.cfg.xml</value>
</list>
</property>
</bean>
hibernate.cfg.xml代码如下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="sessionFactory">
<property name="hibernate.connection.driver_class">
com.microsoft.sqlserver.jdbc.SQLServerDriver
</property>
<property name="hibernate.connection.password">123456</property>
<property name="hibernate.connection.url">
jdbc:sqlserver://localhost:1433; DatabaseName=oadb
</property>
<property name="hibernate.connection.username">sa</property>
<property name="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
</property>
<property name="hibernate.show_sql">true</property>
<property name="hiberante.format_sql">true</property>
<property name="hibernate.cache.provider_class">
org.hibernate.cache.EhCacheProvider
</property>
<property name="hibernate.connection.autocommit">false</property>
<mapping class="com.huaxia.oaapp.entity.User" />
</session-factory>
</hibernate-configuration>
2 配置proxool连接池
第一种：spring中配置proxool非常简单，代码如下
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hiberante.format_sql">true</prop>
<prop key="hibernate.proxool.pool_alias">myDataSource</prop>
<prop key="hibernate.proxool.xml">Proxool.xml</prop>
</props>
</property>
</bean>
其中
Proxool.xml在根目录下，大致内容如下
<something-else-entirely>
<proxool>
<alias>myDataSource</alias>
<driver-url>
jdbc:sqlserver://localhost:1433; DatabaseName=test
</driver-url>
<driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
<driver-properties>
<property name="user" value="sa"/>
<property name="password" value="123456"/>
</driver-properties>
<house-keeping-sleep-time>1000</house-keeping-sleep-time>
<maximum-connection-count>2</maximum-connection-count>
<house-keeping-test-sql>select CURRENT_DATE</house-keeping-test-sql>
</proxool>
</something-else-entirely>
第二种：上面是嵌入了proxool.xml文件，其实也可以直接嵌入proxool属性，这样就不用再建立Proxool.xml文件了，代码如下
<bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource" destroy-method="close">
<property name="alias" value="test"></property>
<property name="delegateProperties">
<value>user=${jdbc.username},password=${jdbc.password}</value>
</property>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="driver" value="${jdbc.driverClassName}"/>
<property name="driverUrl" value="${jdbc.url}"/>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hiberante.format_sql">true</prop>
</props>
</property>
</bean>
此处说明一下：属性中的user和password不起任何作用，需要用delegateProperties方式写一下，否则会报错误，如下
org.springframework.transaction.CannotCreateTransactionException:
Could not open JDBC Connection for transaction; nested exception is
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user
''. The user is not associated with a trusted SQL Server connection.
但是user和password还不能被去掉。
除了上面的用delegateProperties之外，还可以将用户名和密码直接写在url后面。
proxool属性的说明，在这里写的比较详细

第三种：在hibernate.cfg.xml中配置proxool连接池，代码如下
applicationContext.xml文件大致配置如下：
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="configLocations">
<list>
<value>classpath:hibernate.cfg.xml</value>
</list>
</property>
</bean>
hibernate.cfg.xml的配置如下：
<hibernate-configuration>
<session-factory name="sessionFactory">
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="show_sql">true</property>
<property name="connection.provider_class">org.hibernate.connection.ProxoolConnectionProvider</property>
<property name="proxool.pool_alias">myDataSource</property>
<property name="proxool.xml">Proxool.xml</property>
<property name="connection.autocommit">=true </property>
<property name="jdbc.batch_size">20</property>
<property name="default_schema">dbo</property>
<mapping class="com.huaxia.oaapp.entity.User" />
<mapping class="com.huaxia.oaapp.entity.Document" />
<mapping class="com.huaxia.oaapp.entity.Certificate" />
</session-factory>
</hibernate-configuration>
其中
Proxool.xml就是要加入的proxool连接池的配置文件
