Spring+JDBC组合开发

使用Spring+JDBC组合开发步骤:

1、配置数据源

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:tx="http://www.springframework.org/schema/tx"
       
       
        xsi:schemaLocation="http://www.springframework.org/schema/beans  
                            http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
                            http://www.springframework.org/schema/context
                            http://www.springframework.org/schema/context/spring-context-2.5.xsd
                            http://www.springframework.org/schema/aop
                            http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
                            http://www.springframework.org/schema/tx
                            http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
                           
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
         <property name="driverClassName" value="oracle.jdbc.OracleDriver"/> 
         <property name="url" value="jdbc:oracle:thin:@Localhost:1521:PORTALDB"/>
         <property name="username" value="test"/>
         <property name="password" value="test"/>
         
         <!-- 连接池启动时的初始设置 -->
         <property name="initialSize" value="5"/>
         <!-- 连接池的最大值 -->
         <property name="maxActive" value="500"/>
         <!-- 最大空闲值。当经过一个高峰时间后,连接池可以将空闲的连接释放一部分,一直到maxIdle为止 -->
         <property name="maxIdle" value="50"/>
         <!-- 最小空闲值。当空闲连接数小于阀值时,连接池就会预申请一些连接,以免洪峰时来不及申请 -->
         <property name="minIdle" value="1"/>
        </bean>   
       
        <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
         <property name="dataSource" ref="dataSource"/>
        </bean>  
        <!-- 采用@Transaction注解方式使用事务 -->
        <tx:annotation-driven transaction-manager="txManager"/>
        <bean id="personService" class="cn.itcast.service.impl.PersonServiceBean" >
         <property name="dataSource" ref="dataSource"></property>
        </bean>
</beans>  

2、配置事务

    配置事务时,需要在XML配置文件中引入声明事务的tx命名空间,事务常见的配置方式有两种:注解方式和基于XML的配置方式。
