我在基于Spring Boot应用程序启动JMS客户端时遇到一些问题。如您在堆栈跟踪中所见：
Error creating bean with name 'connectionFactory' defined in class path resource [com/configuration/JMSConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.jms.ConnectionFactory]: Factory method 'connectionFactory' threw exception; nested exception is java.lang.ClassCastException: org.apache.activemq.ra.ActiveMQConnectionFactory cannot be cast to javax.jms.ConnectionFactory

当Spring尝试创建Connection工厂时，将引发ClassCastException。我不明白为什么。也许我忘记了什么。 我在属性文件中输入了我在jboss中使用的Connection Factory的名称：
jndi-name-connection-factory=java:/ConnectionFactory
您可以在standalone.xml文件中看到
<subsystem xmlns="urn:jboss:domain:resource-adapters:5.0">
<resource-adapters>
<resource-adapter id="org.apache.activemq.ra">
<module slot="main" id="org.apache.activemq"/>
<transaction-support>XATransaction</transaction-support>
<config-property name="ServerUrl">
failover:(tcp://host:port,tcp://host2:port)?randomize=false&timeout=10000&jms.sendTimeout=2000&maxReconnectDelay=10000
</config-property>
<config-property name="UseInboundSession">
false
</config-property>
<connection-definitions>
<connection-definition class-name="org.apache.activemq.ra.ActiveMQManagedConnectionFactory" jndi-name="java:/ConnectionFactory" enabled="true" use-java-context="true" pool-name="ActiveMQConnectionFactoryPool" use-ccm="true">
<xa-pool>
<min-pool-size>2</min-pool-size>
<max-pool-size>50</max-pool-size>
</xa-pool>
<validation>
<background-validation>false</background-validation>
<background-validation-millis>30000</background-validation-millis>
<use-fast-fail>false</use-fast-fail>
</validation>
<recovery no-recovery="true">
<recover-credential>
<user-name>user</user-name>
<password>psw</password>
</recover-credential>
</recovery>
</connection-definition>
</connection-definitions>
<admin-objects>
而且，您可以在我的配置类中使用它：
import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.broker.BrokerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.*;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.support.converter.MarshallingMessageConverter;
import org.springframework.jms.support.converter.MessageConverter;
import org.springframework.jmx.support.MBeanServerConnectionFactoryBean;
import org.springframework.jndi.JndiObjectFactoryBean;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import javax.jms.ConnectionFactory;
import javax.jms.Queue;
import javax.naming.InitialContext;
import javax.naming.NamingException;
@EnableJms
@Configuration
@EnableAutoConfiguration
@PropertySources({
@PropertySource("classpath:conf/application.properties")
})
public class JMSConfiguration {
@Value("${activemq.broker.connector}")
private String connector;
@Value("${jndi-name-connection-factory}")
private String factory;
@Bean
public ConnectionFactory connectionFactory() throws NamingException{
ConnectionFactory connectionFactory = InitialContext.doLookup(factory);
return connectionFactory;
}
@Bean
public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory,
DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
factory.setMessageConverter(messageConverter());
// This provides all boot's default to this factory, including the message converter
configurer.configure(factory, connectionFactory);
// You could still override some of Boot's default if necessary.
return factory;
}
@Bean
public Queue jndiDataSource() throws IllegalArgumentException,
NamingException {
JndiObjectFactoryBean bean = new JndiObjectFactoryBean(); // create JNDI data source
bean.setJndiName(factory); // jndiDataSource is name of JNDI data source
bean.setProxyInterface(Queue.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet();
return (Queue) bean.getObject();
}
//@Bean
MessageConverter messageConverter() {
MarshallingMessageConverter converter = new MarshallingMessageConverter();
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setClassesToBeBound(Notification.class);
converter.setMarshaller(marshaller);
//converter.unmarshaller = marshaller()
// set this converter on the implicit Spring JMS template
return converter;
}
}
我尝试也使用ActiveMQConnectionFactory代替ConnectionFactory，但是应用程序无法进行此强制转换。
