Question

我希望向可以在注册时设置自己的ETA的用户发出提醒。因此，如果他无法及时到达那么我希望向用户发出警报。我如何实现这一目标？ Ii在wso2esb中引用了TASK SCHEDULING，但它定义了静态请求和静态时间，每个用户的时间都不同。我该怎么做动态？即使我尝试过ACTIVE MQ调度但没有用。对此有何帮助？

PROPERTY NAME   TYPE    DESCRIPTION
AMQ_SCHEDULED_DELAY long    The time in milliseconds that a message will wait before being scheduled to be delivered by the broker
AMQ_SCHEDULED_PERIOD    long    The time in milliseconds to wait after the start time to wait before scheduling the message again
AMQ_SCHEDULED_REPEAT    int The number of times to repeat scheduling a message for delivery
AMQ_SCHEDULED_CRON  String  Use a Cron entry to set the schedule.

我添加了像这样的代理

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="JMSSCHEDULE11"
       transports="https,http"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <property name="OUT_ONLY" value="true"/>
         <log level="full"/>
         <property name="messageType" value="application/json" scope="axis2"/>
         <property name="OUT_ONLY" value="true"/>
         <property name="FORCE_SC_ACCEPTED"
                   value="true"
                   scope="axis2"
                   type="STRING"/>
         <property name="AMQ_SCHEDULED_DELAY"
                   value="3000000000000000"
                   scope="transport"
                   type="STRING"/>
         <send>
            <endpoint>
               <address uri="jms:/JMSSCHEDULE?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://127.0.0.1:61616&transport.jms.DestinationType=queue"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence/>
   </target>
   <parameter name="delay">300000000000</parameter>
   <description/>
</proxy>

即使它不起作用

Answer 1

您需要在默认情况下禁用的activemq中启用调度程序支持。

您需要在以下位置编辑文件：D：\ Installed \ apache-activemq-5.9-SNAPSHOT \ conf \ activemq.xml

<broker xmlns="http://activemq.apache.org/schema/core" advisorySupport="false" brokerName="localhost" dataDirectory="${activemq.data}" schedulerSupport="true">

启用调度程序后，您可以在ActiveMQ的管理员Web控制台上看到新标签“预定”

 http://localhost:8161/admin/scheduled.jsp

Answer 2

您需要添加此属性并需要修改activemq.xml文件作为schedulerSupport =＆＃34; true

<property name="AMQ_SCHEDULED_DELAY"
                   value="3000000000000000"
                   scope="transport"
                   type="STRING"/>
