Import Spring XML files into @Configuration

This is common to mix XML configuration into Spring @Configuration, because developers are used to the XML namespaces. In Spring, you can use @ImportResource to import Spring XML configuration files into @Configuration :

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
@Configuration
@ImportResource("classpath:/config/spring.xml")
public class AppConfig {

Another example

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.context.annotation.Import;
@Configuration
@Import({ AppConfigWeb.class })
@ImportResource("classpath:/config/spring.xml")
public class AppConfig {

P.S @ImportResource has been available since Spring 3.0
