All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.core.Ordered, org.springframework.core.PriorityOrdered

public class SystemPropertyPlaceholderConfigurer
extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer

Property Placeholder Configurer that allows for reading a file that is indicated via a system property. This allows for properties to be loaded from a file that is designated at runtime, and doesn't need to be on the classpath. To Use, Enter Spring Bean as follows:

   
                
                  
                  
                          
                                classpath:application.properties
                          
                  
          
 

Then start your application as follows: java -Dapplication.properties.location=/root/test.properties -jar application.jar This will load properties from application.properties first (from the classpath), then override with /root/test.properties.
