[Java教程]Druid连接池的基本配置

<!-- 阿里 druid 数据库连接池 --> 
 < bean id = "dataSource" class = "com.alibaba.druid.pool.DruidDataSource"destroy-method = "close" >      <!-- 数据库基本信息配置 -->     < property name = "url" value = "${url}" />      < property name = "username" value = "${username}" />      < property name = "password" value = "${password}" />      < property name = "driverClassName" value = "${driverClassName}" />      < property name = "filters" value = "${filters}" />      <!-- 最大并发连接数 -->     < property name = "maxActive" value = "${maxActive}" />     <!-- 初始化连接数量 -->     < property name = "initialSize" value = "${initialSize}" />     <!-- 配置获取连接等待超时的时间 -->     < property name = "maxWait" value = "${maxWait}" />     <!-- 最小空闲连接数 -->     < property name = "minIdle" value = "${minIdle}" />      <!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 -->     < property name = "timeBetweenEvictionRunsMillis" value ="${timeBetweenEvictionRunsMillis}" />     <!-- 配置一个连接在池中最小生存的时间,单位是毫秒 -->     < property name = "minEvictableIdleTimeMillis" value ="${minEvictableIdleTimeMillis}" />      < property name = "validationQuery" value = "${validationQuery}" />      < property name = "testWhileIdle" value = "${testWhileIdle}" />      < property name = "testOnBorrow" value = "${testOnBorrow}" />      < property name = "testOnReturn" value = "${testOnReturn}" />      < property name = "maxOpenPreparedStatements" value ="${maxOpenPreparedStatements}" />     <!-- 打开 removeAbandoned 功能 -->     < property name = "removeAbandoned" value = "${removeAbandoned}" />     <!-- 1800 秒,也就是 30 分钟 -->     < property name = "removeAbandonedTimeout" value ="${removeAbandonedTimeout}" />     <!-- 关闭 abanded 连接时输出错误日志 -->      < property name = "logAbandoned" value = "${logAbandoned}" />  </ bean >

温馨提示:

 

Druid 是目前最好的数据库连接池,在功能、性能、扩展性方面,都超过其他数据库连接池,
包括 DBCP、C3P0、BoneCP、Proxool、JBoss DataSource。
Druid 已经在阿里巴巴部署了超过 600 个应用,经过多年多生产环境大规模部署的严苛考验。
