spring配置数据源方式

[代码] JNDI方式

 

1、SpringJNDI数据源配置信息：

  <bean id="dataSource"class="org.springframework.jndi.JndiObjectFactoryBean">

   <property name="jndiName">

    <value>java:comp/env/jcptDataSourceJNDI</value>

   </property>

  </bean>

  jcptDataSourceJNDI是tomcat或者其他应用服务器配置的JNDI.

  

2、关于JNDI的配置(tomcat)：

  修改tomcat目录conf/context.xml文件：

  <Resource name="jcptDataSourceJNDI"auth="Container"type="javax.sql.DataSource"

      maxActive="100"maxIdle="30"maxWait="10"   username="tysp"

      password="12345678"driverClassName="oracle.jdbc.driver.OracleDriver"

      url="jdbc:oracle:thin:@192.168.1.35:1521:orcl"/>  

  

3、通过JNDI获取DataSource:

  Context context =newInitialContext();

  DataSource ds = (DataSource)context.lookup("java:comp/env/jcptDataSourceJNDI");

 

[代码] 使用DBCP连接池获取

 

要在Spring中使用DBCP连接池，需要引入commons-collections.jar、commons-dbcp.jar和commons-pool.jar。

  

<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:@192.168.1.35:1521:orcl"></property>

        <property name="username"value="or_meal"></property>

        <property name="password"value="or_meal"></property>

        <property name="maxActive"value="100"></property>

        <property name="maxIdle"value="30"></property>

        <property name="maxWait"value="10"></property>

        <property name="defaultAutoCommit"value="false"></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="show_sql">true</prop>

                <prop key="format_sql">true</prop>

            </props>

        </property>

        <property name="mappingResources">

        <list></list>

        </property>

    </bean>

 

[代码] 使用DriverManagerDataSource

<bean id="dataSource"

        class="org.springframework.jdbc.datasource.DriverManagerDataSource">

        <property name="driverClassName">

            <value>oracle.jdbc.driver.OracleDriver

            </value>

        </property>

        <property name="url">

            <value>jdbc:oracle:thin:@192.168.1.35:orcl

            </value>

        </property>

        <property name="username">

            <value>or_meal</value>

        </property>

        <property name="password">

            <value>or_meal</value>

        </property>

    </bean>
