为什么redeliveryPlugin不向DLQ发送消息？

Question

如果超出该数量，我尝试自动将消息发送到DLQ，然后重试。为此，我使用redeliveryPlugin。
我有一个ActiveMQ（broker.xml）的配置

                                          maximumRedeliveries="-1"/>
                    </redeliveryPolicyEntries>

            </redeliveryPolicyMap>

在此图片参数中，JMSXDeliveryCount的值为3，我希望插件将消息发送到DLQ，但这没有发生，我也不明白为什么

UPD：

我在配置schedulerSupport =“ true”中添加了内容，但是在ActiveMQ控制台中，已安排的列表为空
