Following this, this and this I came up with the following Maven configuration that replaces/filters placeholders from your hibernate.cfg.xml file with properties from a properties file:

    
        
            org.apache.maven.plugins
            maven-resources-plugin
            2.6
            

                
                    copy-resources
                    
                    validate
                    
                        copy-resources
                    
                    
                        ${basedir}/target/extra-resources
                        
                            
                                src/main/resources
                                true
                            
                        
                    
                
            

        
    

    
    
        src/main/resources/dbConnection.properties
    
    
        
            src/main/resources
            true
            
                *
            
            
                hibernate.cfg.xml
            
        
    

With this configuration, you can run the validate Maven goal to generate the filtered files and see if they are relpaced correctly

This is of course useful if you are using Maven.
