Spring XML Configuration Properties file

Background: The database information is generally configured in the Db.properties file, but the properties file parsing is a troublesome thing

The STRUTS2 Integrated Spring Framework provides a way to parse the properties file, in the following steps:

1. Make the following configuration in Spring-all.xml

<?xml version= "1.0" encoding= "UTF-8"?>
<beans xmlns= "Http://www.springframework.org/schema/beans"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
Xsi:schemalocation= "http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/ Spring-beans-2.5.xsd ">

<bean id= "Propertyconfigurer"
class= "Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
<property name= "Locations" >
<list>
<value>classpath:properties/db.properties</value>
</list>
</property>
</bean>
<import resource= "Spring-db.xml"/>

</beans>

2, db.properties file to do the following configuration

#jdbc Properties, development environment
Jdbc.driverclassname=oracle.jdbc.driver.oracledriver
#jdbc. Url=jdbc:oracle:thin:@192.168.32.222:1521:smpdev
Jdbc.url=jdbc:oracle:thin: @localhost: 1521:ORCL
Jdbc.username=smp
#jdbc. Username=smpdev
#jdbc. USERNAME=SMP
Jdbc.password=linkage
#jdbc. PASSWORD=SMP

Jdbc.maxactive=20
jdbc.maxidle=2
Jdbc.minidle=1
jdbc.initialsize=2
Jdbc.accesstounderlyingconnectionallowed=true
