spring配置dbcp连接池

一、配置db.properties属性文件

#database connection config
connection.username=sa
connection.password=sa
connection.url=jdbc:sqlserver://192.168.10.3:1433;databaseName=Adw
connection.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
#connection.initialSize=10
connection.maxActive=100
connection.maxIdle=30
connection.minIdle=5
connection.maxWait=5000
connection.removeAbandoned=true
connection.removeAbandonedTimeout=3000
connection.logAbandoned=false

二、spring配置文件中,配置读取db.properties文件的bean

<bean id="config"
  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="location">
   <value>classpath:db.properties</value>
  </property>
 </bean>

三、最后配置dataSource

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
  <property name="username" value="${connection.username}"></property>
  <property name="password" value="${connection.password}"></property>
  <property name="url" value="${connection.url}"></property>
  <property name="driverClassName" value="${connection.driverClassName}"></property>
  <!-- <property name="initialSize" value="${connection.initialSize}"></property> -->
  <property name="maxActive" value="${connection.maxActive}"></property>
  <property name="maxIdle" value="${connection.maxIdle}"></property>
  <property name="minIdle" value="${connection.minIdle}"></property>
  <property name="maxWait" value="${connection.maxWait}"></property>
  <property name="removeAbandoned" value="${connection.removeAbandoned}"></property>
  <property name="removeAbandonedTimeout" value="${connection.removeAbandonedTimeout}"></property>
  <property name="logAbandoned" value="${connection.logAbandoned}"></property>
 </bean>

注： dataSource就是数据库连接池
