How should I configure a global variabel

[magott]

I would like to configure global variable identifying my application. I would like to do this in a matter where changing it is just a matter of changing a configuration file, leaving the way it's retrieved in code unchanged.

I'd like to access this Id in my interceptor/filter framework code, and I would prefer not to inject values into the interceptor/filter.

A static getter would be preferable, but then I won't be able to inject the application id using Spring.

So, do anyone have a suggestion on how to best do this?

U can try using singleton class on spring :

this some example :

MyService :

package net.sf.hrs.services.impl;

public class MyService
{
    private static MyService instance;

    private String applicationName;

    public void setApplicationName(String applicationName)
    {
        this.applicationName = applicationName;
    }

    public String getApplicationName()
    {
        return applicationName;
    }

    public static MyService getInstance()
    {
        if (instance == null) instance = new MyService();
        return instance;
    }
}

applicationContext :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
    <bean id="test" class="net.sf.hrs.services.impl.MyService" factory-method="getInstance">
        <property name="applicationName" value="test"/>
    </bean>
</beans>

Your application code :

public class HelloWorld
{
   public void write()
   {
       MyService.getInstance().getApplicationName();  
   }
}

Hope this can help u
