Question

我正在尝试使用以下代码在Spring-Boot项目中配置RecipientListRouter：

@Bean
public RecipientListRouter locateIncomingCompleteRouter(){
    RecipientListRouter router = new RecipientListRouter();
    router.addRecipient("c1");
    router.addRecipient("c2");
    List<MessageChannel> channels = new ArrayList<MessageChannel>();
    channels.add(c3());
    router.setChannels(channels);
    return router;
}

我收到了以下错误

Caused by: java.lang.IllegalArgumentException: BeanFactory must not be null

Answer 1

addRecipients用于在创建bean之后动态添加收件人，而不是在bean创建过程中。

要使用@Bean定义连接收件人，请使用

public void setChannels(List<MessageChannel> channels)

或

public void setRecipients(List<Recipient> recipients)

您需要参考实际频道;不只是他们的名字。
