一、從JNDI獲得DataSource

1.在tomcat伺服器中的配置示例，在tomcat目錄conf/context.xml檔案中新增：

 <Resource 
     name="jdbc/writeDataSource" 
     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"/> 
 

2.在resin伺服器中的配置示例,在resin目錄conf/resin.xml檔案中新增

<database jndi-name='jdbc/writeDataSource'>
 <driver type="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource"> 
<url>jdbc:mysql://localhost:3306/yfhesuanuseUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull</url> 
<user>root</user> 
<password>12345678</password>
 </driver> 
<prepared-statement-cache-size>8</prepared-statement-cache-size>
<max-connections>30</max-connections>
<max-idle-time>30s</max-idle-time> 
<connection-wait-time>30000</connection-wait-time> 
<transaction-timeout>30000</transaction-timeout> 
 </database>
 

3.SpringJNDI資料來源配置資訊

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

在賦值到value時必須加上"java:comp/env/"。

注意：記得要把資料庫驅動的jar包丟到伺服器的lib下。

二、從第三方的連線池獲得DataSource

要在Spring中使用DBCP連線池，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>

三、使用DriverManagerDataSource獲得DataSource

<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>
