How to dynamically change the Bean properties

[mullin]

I configure the hsqldb setting on the xml file like the above,

But, I want my application accepts a command arguement and then change the "url" property to

jdbc:hsqldb:C:\RAD Workspace\client-spring\<arg_value>\db\clientcache

therefore, my application can support multiple instances running today if needed. But, how can I do it?


program
======

appContext = new ClassPathXmlApplicationContext(new String[] {
"config/fox-client.xml"
});


xml file
======

<bean id="clientCacheDS" class="org.springframework.jdbc.datasource.DriverM anagerDataSource">
<property name="driverClassName">
<value>org.hsqldb.jdbcDriver</value>
</property>
<property name="url">
<value>jdbc:hsqldb:C:\RAD Workspace\client-spring\db\clientcache</value>
</property>
<property name="username">
<value>sa</value>
</property>
<property name="password">
<value></value>
</property>
</bean>

You might want to take a look at the PropertyPlaceHolderConfigurer. That one operates on property files. That way you can have different property files for different environments.

Have you looked at PropertyPlaceholderConfigurer? This can use system proeprties to replace values. So your command line parameter -Dmyurl=blah should work fine.
