Spring Boot load beans from context xml in library

Question

I have two applications:

• Application child : it's a Spring app with XML Schema-based configuration. So We have an applicationContext.xml .

• Application parent : Spring Boot app. Uses application child as a library.

Is possible to load all beans defined in child XML, and put them into parent context?

Answer 1

Yes it is possible.

From javadoc :

As mentioned above, @Configuration classes may be declared as regular Spring definitions within Spring XML files. It is also possible to import Spring XML configuration files into @Configuration classes using the @ImportResource annotation . Bean definitions imported from XML can be injected using @Autowired or @Import.

Here an example from the same javadoc that mix beans loaded from xml in beans defined in configuration class:

 @Configuration
 @ImportResource("classpath:/com/acme/database-config.xml")
 public class AppConfig {
     @Inject DataSource dataSource; // from XML

     @Bean
     public MyBean myBean() {
         // inject the XML-defined dataSource bean
         return new MyBean(this.dataSource);
     }
 }
