spring集成jdbc编码与事务管理
<context:property-placeholder location="classpath:jdbc.properties"/> <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>
在classpath目录下增加一个jdbc.properties文件,里面存储 属性值 键值对 增加一句代码
<context:property-placeholder location="classpath:jdbc.properties"/>
然后通过value="${xxxx}"引用属性的值。
当出现open quote is expected for attribute这个错误时,可以检查
<context:property-placeholder location="classpath:jdbc.properties"/>
这句代码是否有问题。
