我创建了一个自定义的processStrategy，它是GenericFileDeleteProcessStrategy的扩展：

@Component
public class AlwaysDeleteProcessStrategy<T> extends GenericFileDeleteProcessStrategy<T> {

    private static final Logger LOGGER = LoggerFactory.getLogger(AlwaysDeleteProcessStrategy.class);

    @Override
    public void rollback(GenericFileOperations<T> operations, GenericFileEndpoint<T> endpoint, Exchange exchange, GenericFile<T> file) throws Exception {
        LOGGER.info("Deleting file despite exception");
        super.commit(operations, endpoint, exchange, file);
    }
}

当在endpoint-dsl中使用它时，它工作得非常好，但是当我用String构建端点时，它就停止工作了：

//Works fine
from(file("src/test/resources/input").advanced().processStrategy(new AlwaysDeleteProcessStrategy()))  

//Doesn't work
from("file://src/test/resources/input?processStrategy=#alwaysDeleteProcessStrategy")

这是我尝试将其添加到String端点时抛出的异常：

Caused by: org.apache.camel.NoSuchBeanException: No bean could be found in the registry for: alwaysDeleteProcessStrategy of type: org.apache.camel.component.file.GenericFileProcessStrategy

我也尝试过手动创建bean，因为@Component注解还不够，但是没有什么效果。我怎样才能让这两种情况都能工作呢？
