Bootstraping a web application with Spring 3.1 and Java based Configuration, part 1 - the AppConfig

AppConfig.java

@Configuration
@ImportResource( { "classpath*:/rest_config.xml" } )
@ComponentScan( basePackages = "org.rest" )
public class AppConfig{
   
   @Bean
   public static PropertyPlaceholderConfigurer properties(){
      PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
      final Resource[] resources = new ClassPathResource[ ] { 
         new ClassPathResource( "persistence.properties" ), 
         new ClassPathResource( "restfull.properties" ) 
      };
      ppc.setLocations( resources );
      ppc.setIgnoreUnresolvablePlaceholders( true );
      return ppc;
   }
   
}
