有没有办法在条件下自动装配bean？

还有一个例子.我们有2个FileManager的实现.其中一个实现应该初始化取决于属性'platform'.属性通过Archaius处理.

@Component
public class AwsPlatformCondition implements Condition {

    @Autowired
    private ArchaiusProperties archaiusProperties;

    @Override
    public boolean matches(ConditionContext conditionContext, AnnotatedTypeMetadata annotatedTypeMetadata) {
        return "aws".equalsIgnoreCase(archaiusProperties.getStringProperty(PropertiesMapper.PLATFORM));
    }
}

.

@Component
public class StandardPlatformCondition implements Condition {

    @Autowired
    private ArchaiusProperties archaiusProperties;

    @Override
    public boolean matches(ConditionContext conditionContext, AnnotatedTypeMetadata annotatedTypeMetadata) {
        return "standard".equalsIgnoreCase(archaiusProperties.getStringProperty(PropertiesMapper.PLATFORM));
    }
}

.

@Component
@Conditional(AwsPlatformCondition.class)
public class AS3FileManager implements FileManager {
...
}

.

@Component
@Conditional(StandardPlatformCondition.class)
public class NativeFileManager implements FileManager {
...
}

此代码不起作用.主要原因是因为条件匹配时ArchaiusProperties bean没有初始化.有没有办法在条件下使用它之前初始化ArchaiusProperties bean？
