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"width="548">
???<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"width="548">
????????<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"
????????width="548">
????????<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>

????????????</props>
????????</property>
????????<property?name="mappingResources">
????????<list></list>
????????</property>
????</bean>
?
[代码]?使用DriverManagerDataSource
<bean?id="dataSource"
????????width="548">
????????<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>
