EJB 3.0'da MessageDrivenBean (MDB) ek açıklamaları yerine ejb-jar.xml kullanabilir miyiz?

Question

EJB 3.0'da @ActivationConfigProperty kullanarak mesaj hedefi türünü, adını vb. Yapılandırdım, ancak EJB 2.0'da olduğu gibi dağıtım tanımlayıcısını (ejb-jar.xml) kullanarak MDB'u yapılandırmak istedim. Bilginize

: JBoss 6

kullanıyorum

kimse bana bu konuda rehberlik eder?

Answer 1

Teşekkürler, ama çok daha basit bir şekilde anladım. Aşağıda,

<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> 

kodu bulunmaktadır.

MDB'yi yapılandırmak için xml içeriği aşağıdadır, aşağıdaki kodu buna göre değiştirebilir.

<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> 

     <resource-ref> 
        <resource-ref-name>jms/ConnectionFactory</resource-ref-name> 
        <resource-type> 
         javax.jms.ConnectionFactory 
        </resource-type> 
         <res-auth>Container</res-auth> 
         <mapped-name>ConnectionFactory</mapped-name> 
         <injection-target> 
          <injection-target-class> 
           com.bean.SomeMessageBean 
          </injection-target-class> 
          <injection-target-name>datasource</injection-target-name> 
         </injection-target> 
       </resource-ref> 
    </message-driven> 
</enterprise-beans>
