spring配置连接池

1 c3p0连接池

<bean id="dataSource"
  class="com.mchange.v2.c3p0.ComboPooledDataSource"
  destroy-method="close" dependency-check="none">
  <property name="driverClass"
   value="com.mysql.jdbc.Driver" />
  <property name="jdbcUrl"
   value="jdbc:mysql://10.3.6.76:3306/mjadc" />
  <property name="properties">
   <props>
    <prop key="c3p0.minPoolSize">5</prop>
    <prop key="hc3p0.maxPoolSize">10</prop>
    <prop key="hc3p0.timeout">60</prop>
    <prop key="c3p0.max_statement">50</prop>
    <prop key="c3p0.testConnectionOnCheckout">true</prop>
    <prop key="user">mobileadc</prop>
    <prop key="password">mobileadc</prop>
   </props>
  </property>
 </bean>

2jndi连接池

tomcat  conf/context.xml配置

<Resource name="jdbc/mysql"
         type="javax.sql.DataSource"
         driverClassName="com.mysql.jdbc.Driver"
         password="mobileadc"
         maxIdle="2"
         maxWait="5000"
         username="mobileadc"
         url="jdbc:mysql://10.3.6.76:3306/mjadc"
         maxActive="10"/>

 jboss /jboss3/server/default/deploy/thirdgs-oracle-ds.xml(是oracle的配置文件 是mysql的  thirdgs-mysql-ds.xml()

 <local-tx-datasource>
      <connection-url>jdbc:oracle:thin:@10.3.6.72:1521:TEST</connection-url>
     <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
      <user-name>lnadc</user-name>
      <password>lnadc</password>
      <min-pool-size>5</min-pool-size>
      <max-pool-size>20</max-pool-size>
      <idle-timeout-minutes>0</idle-timeout-minutes>
      <track-statements>true</track-statements>
   </local-tx-datasource>

spring配置

<bean id="dataSource"
  class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName">
  <value>java:comp/env/jdbc/mysql</value>
  </property>
  </bean>

3 proxoo连接池l

bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource" destroy-method="close">
  <property name="driver" value="${hibernate.driverClass}" />

或者直接写成<property name="driver"> <value>com.mysql.jdbc.Driver</value></property>
  <property name="driverUrl" value="${hibernate.jbdc.url}" />
  <property name="user" value="${hibernate.jbdc.user}" />
  <property name="password" value="${hibernate.jdbc.password}" />
  <property name="alias" value="proxoolPool" />
  <property name="houseKeepingSleepTime" value="30000" />

  <property name="prototypeCount" value="20" />
  <property name="maximumConnectionCount" value="${hibernate.jdbc.maxConn}" />
  <property name="minimumConnectionCount" value="${hibernate.jdbc.minConn}" />
  <property name="trace" value="true" />
  <property name="verbose" value="true" />
 </bean>

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
  <property name="dataSource" ref="dataSource" />
  <property name="schemaUpdate" value="${hibernate.schemaUpdate}" />
  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">${hibernate.dialect}</prop>
    <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
    <prop key="hibernate.format_sql">true</prop>
    <prop key="hibernate.use_outer_join">true</prop>
    <prop key="hibernate.jdbc.fetch_size">50</prop>
    <prop key="hibernate.jdbc.use_streams_for_binary">true</prop>
    <prop key="hibernate.bytecode.use_reflection_optimizer">true</prop>
    <prop key="hibernate.query.substitutions">true 1,false 0,yes 'Y',no 'N'</prop>
   </props>
  </property>
  <property name="annotatedClasses">
   <list>
    <value>com.mysteel.entity.xxx</value>
   </list>
  </property>
 </bean>

在默认通过myeclipse生成的配置里，spring使用的是apache的dbcp连接池

<bean id="dataSource"
  class="org.apache.commons.dbcp.BasicDataSource">
  <property name="driverClassName"
   value="com.mysql.jdbc.Driver">
  </property>
  <property name="url"
   value="jdbc:mysql://localhost:3306/mysql">
  </property>
  <property name="username" value="root"></property>
  <property name="password" value="root"></property>
 </bean>
