I use following line of code to read config.properties file in my spring mvc configuration servlet xml file.
<context:property-placeholder location="file:///${config.properties}" />
config.properties contains a property say: propertyName = propertyValue
I want to use this propertyName's value in spring mvc configuration servlet xml file.
Here is an example of configuring as pool with properties taken from a properties file
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@${database.url}" />
<property name="username" value="${database.username}" />
<property name="password" value="${database.password}" />
<property name="validationQuery" value="SELECT 1 FROM DUAL" />
<property name="testWhileIdle" value="true" />
<property name="timeBetweenEvictionRunsMillis" value="300000" />
<property name="numTestsPerEvictionRun" value="6" />
<property name="minEvictableIdleTimeMillis" value="1800000" />
<property name="initialSize" value="3" />
<property name="maxActive" value="75" />
<property name="maxIdle" value="75" />
<property name="maxWait" value="5000" />
<property name="poolPreparedStatements" value="true" />
<property name="maxOpenPreparedStatements" value="100" />
</bean>
The property file contains there rows
database.url=localhost:1521:xe
database.username=dbusername
database.password=dbpassword
I guess you need to add
<context:property-placeholder location="file:///${config.properties}" />
to your servlet.xml file.
