在部署时更改主题读取MDB的激活配置

在部署时更改主题读取MDB的激活配置

代替任何部署时解决方案，我编写了一个

ejb-jar.xml

配置，可以在构建时进行修改。它的内容如下：

<?xml version="1.0"?> <ejb-jar 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"      version="3.1">    <enterprise-beans>        <message-driven id="MySpecialMDB"> <display-name>MySpecialMDB</display-name> <ejb-name>TopicReaderBean</ejb-name> <ejb-class>my.TopicReaderBean</ejb-class> <transaction-type>Container</transaction-type> <message-destination-type>javax.jms.Topic</message-destination-type> <activation-config>     <activation-config-property>         <activation-config-property-name>destinationType</activation-config-property-name>         <activation-config-property-value>javax.jms.Topic</activation-config-property-value>     </activation-config-property>     <activation-config-property>         <activation-config-property-name>subscriptionDurability</activation-config-property-name>         <activation-config-property-value>Durable</activation-config-property-value>     </activation-config-property>     <activation-config-property>         <activation-config-property-name>subscriptionName</activation-config-property-name>         <activation-config-property-value>${subscriptionName}</activation-config-property-value>     </activation-config-property> </activation-config>        </message-driven>    </enterprise-beans></ejb-jar>
