EJB 3.0의 MessageDrivenBean (MDB)에 대한 주석 대신 ejb-jar.xml을 사용할 수 있습니까?

Question

EJB 3.0에서 메시지 대상 유형, 이름 등을 @ActivationConfigProperty으로 구성했지만 EJB 2.0에서와 같이 배포 설명자 (ejb-jar.xml)를 사용하여 MDB을 구성하려고했습니다. 참고로

Answer 1

고맙습니다.하지만 나는 훨씬 간단한 방법으로 알아 냈습니다. 아래 코드는

<ejb-jar id="ejb-jar_ID" version="3.1" 
     xmlns="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
          http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd"> 

    <display-name>SampleTransactionMDB</display-name> 
    <enterprise-beans> 
    <message-driven> 
     <display-name>SampleTransactionMDB</display-name> 
     <ejb-name>SampleTransactionMDB</ejb-name> 
     <ejb-class>com.example.SampleTransactionMDB</ejb-class> 
     <transaction-type>Container</transaction-type> 
     <activation-config> 
     <activation-config-property> 
      <activation-config-property-name>destinationType</activation-config-property-name> 
      <activation-config-property-value>javax.jms.Queue</activation-config-property-value> 
     </activation-config-property> 
     <activation-config-property> 
      <activation-config-property-name>destination</activation-config-property-name> 
      <activation-config-property-value>/queue/SampleTransactionQueue</activation-config-property-value> 
     </activation-config-property> 
     </activation-config> 
    </message-driven> 
    </enterprise-beans> 
    <assembly-descriptor> 
    </assembly-descriptor> 
</ejb-jar>

다음은 MDB 구성을위한 xml 콘텐츠이며, 이에 따라 아래 코드를 수정할 수 있습니다.

<enterprise-beans> 
    <message-driven> 
     <ejb-name>SomeMessageBean</ejb-name> 
     <ejb-class> 
      com.bean.SomeMessageBean 
     </ejb-class> 
     <messaging-type>javax.jms.MessageListener</messaging-type> 
     <transaction-type>Container</transaction-type> 
     <message-destination-type> 
      javax.jms.Queue 
     </message-destination-type> 
     <activation-config> 
      <activation-property> 
       <activation-config-property-name>destinationType 
       </activation-config-property-name> 
       <activation-config-property-value>javax.jms.Queue 
       </activation-config-property-value> 
      </activation-property> 
      <activation-property> 
       <activation-config-property-name>messageSelector 
       </activation-config-property-name> 
       <activation-config-property-value>MessageFormat = 'Version 3.4' 
       </activation-config-property-value> 
      </activation-property> 
      <activation-property> 
       <activation-config-property-name>acknowledgeMode 
       </activation-config-property-name> 
       <activation-config-property-value>Auto-acknowledge 
       </activation-config-property-value> 
      </activation-property> 
     </activation-config>
