myeclipse10使用spring框架结合jdbc操作数据库
步骤:
1、引入必要的jar包,使用到了如下的jar包
spring.jar
aspectjrt.jar
aspectjweaver.jar
cglib-nodep-2.1.3.jar
common-annotations.jar
common-logging.jar
common-dbcp.jar
common-pool.jar
mysql-connector-java-5.1.13.jar
2、配置命名空间
<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:<span style="color:#ff0000;">tx="http://www.springframework.org/schema/tx</span>" 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 <span style="color:#ff0000;"> http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd</span>">
3、配置数据源
使用的是从properties读取属性,下面蓝色部分是引入属性文件必要的代码,其中
jdbc.properties是属性文件的名称。
<span style="color:#000066;"><context:property-placeholder location="classpath:jdbc.properties"/></span><!-- 属性占位,提取配置文件中的值 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driverClassName}"/> <property name="url" value="${url}"/> <property name="username" value="${username}"/> <property name="password" value="${password}"/> <!-- 连接池启动时的初始值 --> <property name="initialSize" value="${initialSize}"/> <!-- 连接池的最大值 --> <property name="maxActive" value="${maxActive}"/> <!-- 最大空闲值.当经过一个高峰时间后,连接池可以慢慢将已经用不到的连接慢慢释放一部分,一直减少到maxIdle为止 --> <property name="maxIdle" value="${maxIdle}"/> <!-- 最小空闲值.当空闲的连接数少于阀值时,连接池就会预申请去一些连接,以免洪峰来时来不及申请 --> <property name="minIdle" value="${minIdle}"/> </bean>

下载文件直接导入到您的myeclipse,然后建立mysql的数据库(数据库文件也在代码文件夹中)。
