1.
引入spring能力:
需要三个Libraries:
Spring
3.0 Persistence JDBC Libraries -
<MyEclipse-Library>
Spring 3.0 AOP Libraries -
<MyEclipse-Library>
Spring 3.0 Core Libraries -
<MyEclipse-Library>
Spring 3.0 Persistence Core
Libraries -
<MyEclipse-Library>
2.
数据源(dataSource):
<!--
1.org.springframework.jdbc.datasource.DriverManagerDataSource
经典jdbc链接的数据源,相当于每次使用DriverManager取得一个链接
-->
<!--bean
id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property
name="driverClassName"
value="oracle.jdbc.driver.OracleDriver"/>
<property
name="url"
value="jdbc:oracle:thin:@localhost:1521:moluo"/>
<property
name="username" value="fengpeng"/>
<property
name="password"
value="fengpeng"/>
</bean-->
<!--
2.org.springframework.jdbc.datasource.SimpleDriverDataSource
和DriverManagerDataSource一样
-->
<!--bean
id="dataSource"
class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
<property
name="driverClass"
value="oracle.jdbc.driver.OracleDriver"/>
<property
name="url"
value="jdbc:oracle:thin:@localhost:1521:moluo"/>
<property
name="username" value="fengpeng"/>
<property
name="password"
value="fengpeng"/>
</bean-->
<!--
3.org.springframework.jdbc.datasource.SingleConnectionDataSource
无论怎么取,都返回同一个连接对象
-->
<!--bean
id="dataSource"
class="org.springframework.jdbc.datasource.SingleConnectionDataSource">
<property
name="driverClassName"
value="oracle.jdbc.driver.OracleDriver"/>
<property
name="url"
value="jdbc:oracle:thin:@localhost:1521:moluo"/>
<property
name="username" value="fengpeng"/>
<property
name="password"
value="fengpeng"/>
</bean-->
<!--
4.用于实战的数据源:org.apache.tomcat.dbcp.dbcp.BasicDataSource
需要引入Spring 3.0 Persistence JDBC Libraries(jar包)
或者使用第三方jar包:tomcat-dbcp.jar <bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
-->
<!--bean
id="dataSource"
class="org.apache.tomcat.dbcp.dbcp.BasicDataSource">
<property
name="driverClassName"
value="oracle.jdbc.driver.OracleDriver"/>
<property
name="url"
value="jdbc:oracle:thin:@localhost:1521:moluo"/>
<property
name="username" value="fengpeng"/>
<property
name="password" value="fengpeng"/>
<property
name="maxActive" value="10"/>
<property
name="maxIdle"
value="5"/>
</bean-->
<bean
id="TestDao" class="dao.TestDaoImple">
<property
name="dataSource"
ref="dataSource"/>
</bean>
3.JdbcTemplate对象的介绍
在application.xml文件中的配置:
<bean
id="dataSource"
class="org.apache.tomcat.dbcp.dbcp.BasicDataSource">
<property
name="driverClassName"
value="oracle.jdbc.driver.OracleDriver"/>
<property
name="url"
value="jdbc:oracle:thin:@localhost:1521:moluo"/>
<property
name="username" value="fengpeng"/>
<property
name="password" value="fengpeng"/>
<property
name="maxActive" value="10"/>
<property
name="maxIdle"
value="5"/>
</bean>
<!--bean
id="connection" factory-bean="dataSource" factory-method="getConnection"
scope="prototype"></bean-->
<bean
id="jdbcTemplate"
class="org.springframework.jdbc.core.JdbcTemplate">
<property
name="dataSource"
ref="dataSource"></property>
</bean>
<bean
id="TestDao"
class="dao.TestDaoImple">
<property
name="jdbcTemplate"
ref="jdbcTemplate"/>
</bean>
在dao.TestDaoImple类中定义JdbcTemplate
private
JdbcTemplate jdbcTemplate;
public void
setJdbcTemplate(JdbcTemplate jdbcTemplate)
{
this.jdbcTemplate =
jdbcTemplate;
}
