直接上代码:

<bean id="propertiesFactoryBean"
class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="locations">
<list>
<value>classpath*:properties/druid.properties</value>
</list>
</property>
</bean> <context:property-placeholder properties-ref="propertiesFactoryBean"/> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="url" value="${jdbc-url}"/>
<property name="username" value="${username}"/>
<property name="password" value="${jdbc-pwd}"/>
<property name="initialSize" value="1"/>
<property name="minIdle" value="1"/>
<property name="maxActive" value="20"/>
<property name="maxWait" value="60000"/>
<property name="timeBetweenEvictionRunsMillis" value="60000"/>
<property name="minEvictableIdleTimeMillis" value="300000"/>
<property name="validationQuery" value="select 1 from dual"/>
<property name="testWhileIdle" value="true"/>
<property name="testOnBorrow" value="false"/>
<property name="testOnReturn" value="false"/>
<property name="poolPreparedStatements" value="true"/>
<property name="maxPoolPreparedStatementPerConnectionSize" value="20"/>
<property name="filters" value="stat" />
</bean>

上面配置了一个druid数据源,其中url,username,password从属性文件druid.properties读取,该属性文件内容如下:

jdbc-url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc-driver=oracle.jdbc.driver.OracleDriver
username=test
jdbc-pwd=123456

发现死活连接不上,一直提示:

java.sql.SQLException: ORA-01017: invalid username/password; logon denied

但其实用户名、密码是对的,可以用pl/sql developer之类的工具连上oracle,正当快要崩溃的时候,把druid.properties中的username=test,换了个名字,改成:

jdbc-user=test

配置也相应改成:

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="url" value="${jdbc-url}"/>
<property name="username" value="${jdbc-user}"/>
<property name="password" value="${jdbc-pwd}"/>

居然就正常了,建议:属性文件中的key最好不要跟druid的成员名重名。
