一、dbcp

spring配置文件

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:jdbc.propertiesvalue>
        list>
    property>
bean>


<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}" />

    <property name="initialSize" value="3" />

    <property name="minIdle" value="3" />

    <property name="maxIdle" value="5" />

    <property name="maxActive" value="15" />
bean>

 jdbc.properties

#dbcp
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/uplatEui?useUnicode=true&characterEncoding=utf-8
username=root
password=password

maven pom.xml

<dependency>
    <groupId>commons-dbcpgroupId>
    <artifactId>commons-dbcpartifactId>
    <version>1.4version>
dependency>

 

二、dbcp2

dbcp2需要jdk1.7，否则会报错：Unsupported major.minor version 51.0

maxActive改为了maxTotal

spring配置文件

<bean id="dataSource2" class="org.apache.commons.dbcp2.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="${driverClassName}" />
    <property name="url" value="${url}" />
    <property name="username" value="${username}" />
    <property name="password" value="${password}" />

    <property name="initialSize" value="3" />

    <property name="minIdle" value="3" />

    <property name="maxIdle" value="5" />

    <property name="maxTotal" value="15" />
bean>

maven pom.xml

<dependency>
    <groupId>org.apache.commonsgroupId>
    <artifactId>commons-dbcp2artifactId>
    <version>2.1.1version>
dependency>
