Question

我正在尝试将WAR部署到我的JBoss服务器，而WAR依赖于EJB模块。当我尝试部署WAR时，出现以下错误：

Failed to start service jboss.deployment.unit Caused by: java.lang.RuntimeException: javax.resource.spi.InvalidPropertyException: Destination is mandatory

我的ejb-jar有：

        <message-driven>
        <ejb-name>LeagueListenerMDB</ejb-name>
        <ejb-class>com.club.ejb.LeagueListenerMDB</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.Topic</activation-config-property-value>
            </activation-config-property>
            <activation-config-property>
                <activation-config-property-name>destination</activation-config-property-name>
                <activation-config-property-value>java:/topic/ejava/projects/contests</activation-config-property-value>
            </activation-config-property>
        </activation-config>
    </message-driven>

我的EJB注释为：

@MessageDriven(activationConfig = {
@ActivationConfigProperty(propertyName = "destination", propertyValue = "java:/topic/ejava/projects/contests"),
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
@ActivationConfigProperty(propertyName = "messageSelector", propertyValue = "ContestAction = 'ContestScheduled' OR "
        + "ContestAction = 'ContestRescheduled' OR "
        + "ContestAction = 'ContestCanceled'"),
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge")

}）

我在注释和ejb-jar中有目的地，所以我不确定问题是什么。

Answer 1

添加

@ActivationConfigProperty(propertyName = "useJNDI", propertyValue = "true"),

我从来没有使用过MDB目的地的java：前缀，所以这可能会让它运行起来：

@ActivationConfigProperty(propertyName = "destination",
    propertyValue = "topic/ejava/projects/contests"),

Answer 2

我知道了，在将MDB重命名为另一个名称（为了避免重复的jndi条目具有相同的名称＆＃34; testQueue＆＃34;）并修改ejb-jar.xml之后，它可以工作：

package test;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.JMSDestinationDefinition;
import javax.jms.Message;
import javax.jms.MessageListener;

@JMSDestinationDefinition(name = "NewMessageBean", interfaceName = "javax.jms.Queue", resourceAdapter = "jmsra", destinationName = "testQueue")
@MessageDriven(activationConfig = {
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
    @ActivationConfigProperty(propertyName = "destination", propertyValue = "willBeOverwrittenInDeploymentDescriptor")
})
public class NewMessageBean implements MessageListener {

    public NewMessageBean() {
    }

    @Override
    public void onMessage(Message message) {
    }

}

仍然需要ActivationConfigProperty目标，否则在部署阶段会抛出异常。

目标值被以下ejb-jar.xml

覆盖

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar version="3.0" 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">
    <enterprise-beans>
        <message-driven>
            <ejb-name>NewMessageBean</ejb-name>
            <ejb-class>test.NewMessageBean</ejb-class>

            <activation-config>
                <activation-config-property>
                    <activation-config-property-name>destination</activation-config-property-name>
                    <activation-config-property-value>/jms/testClientQueue</activation-config-property-value>
                </activation-config-property>
            </activation-config>
        </message-driven>
    </enterprise-beans>
</ejb-jar>

使用此ejb-jar.xml，mdb连接到/ jms / testClientQueue

将消息驱动Bean部署到JBoss服务器
