刚刚开始JMS ActiveMQ Acknowledgements着手在Spring工作.到目前为止,我有一个完美的消费者工作,除了当我不确认消息时,它仍然从队列中取出(我希望它留在那里或以死信队列结束).

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jms="http://www.springframework.org/schema/jms"
       xmlns:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="

http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-3.0.xsd">

    <!-- A JMS connection factory for ActiveMQ -->
    <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"
    p:brokerURL="failover://(tcp://jms1:61616,tcp://jms2:61616)?randomize=false&amp;jms.redeliveryPolicy.maximumRedeliveries=5" />

    <!-- A POJO that implements the JMS message listener -->
    <bean id="simpleMessageListener" class="com.company.ConsumerClass" />

    <!-- A JMS namespace aware Spring configuration for the message listener container -->
    <jms:listener-container
            container-type="default"
            connection-factory="connectionFactory"
            acknowledge="client"
            concurrency="10-50"
            cache="consumer">
        <jms:listener destination="someQueue" ref="simpleMessageListener" method="onMessage" />
    </jms:listener-container>
</beans>

在ConsumerClass中,我的简单消费者看起来像这样:

@Override public final void onMessage(Message message) {
    Object postedMessage = null; …

一旦用户输入足够的文本来溢出控件的宽度,我试图让我的NSTextField的高度增长(就像在iChat或Adium中一样)(如本文所述)

我已经接受了接受的答案,但我似乎无法让它发挥作用.我已将我的尝试上传到http://scottyob.com/pub/autoGrowingExample.zip

理想情况下,当文本增长时,包含的窗口应随之增长,但我正在尝试婴儿步骤.
