How to collect and inject all beans of a given type in Spring XML configuration

by

Old question and in Spring 3.1 it is possible:

public class PluginPrototypeTest extends ASpringWebTest {
  @Autowired
  Collection<IDummyRepo> repos;

  @Test
  public void cacheTest() {
    assertNotNull(repos);
    assertEquals(2, repos.size());
    for(IDummyRepo r: repos){
      System.out.println(r.getName());
    }
  }
}

@Repository
public class DummyRepo implements IDummyRepo {
  @Override
  public String getName(){
    return "DummyRepo";
  }
}
@Repository
public class DummyRepo2 implements IDummyRepo {
  @Override
  public String getName(){
    return "DummyRepo2";
  }
}
