How to create Configuration class with Beans in spring boot? - eclipse

Question

I am converting a project done using spring jms into spring boot project. I dont know how to convert the context.xml in spring jms into the configuration class in spring boot. My context.xml is as follows
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>file:./config-env-receiver.properties</value>
</property>
</bean>
<bean id="stepConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
<property name="hostName">
<value>${mq.hostname.step}</value>
</property>
<property name="port">
<value>${mq.port.step}</value>
</property>
<property name="channel">
<value>${mq.channel.step}</value>
</property>
<property name="queueManager">
<value>${mq.queuemanager.step}</value>
</property>
<property name="transportType">
<value>1</value>
</property>
</bean>
<bean id="jmsDestination" class="com.ibm.mq.jms.MQQueue">
<constructor-arg value="${mq.queuename.step}" />
</bean>
<bean
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="stepConnectionFactory" />
<property name="sessionTransacted" value="true" />
<property name="destinationName" value="${mq.queuename.step}" />
<property name="exceptionListener" ref="exceptionListener" />
<property name="messageListener" ref="stepOutListenerItemCreateUpdate" />
</bean>
<bean id="exceptionListener" class="com.message.view.CustomException">
</bean>
<bean id="stepOutListenerItemCreateUpdate"
class="com.message.view.WMQueueMessageConsumer">
</bean>
<bean id="springConnectionFactory"
class="org.springframework.jms.connection.SingleConnectionFactory">
<property name="targetConnectionFactory" ref="stepConnectionFactory" />
</bean>
<bean id="jmsTemplateStep" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory" ref="springConnectionFactory" />
<property name="defaultDestination" ref="jmsDestination" />
</bean>
<context:component-scan base-package="com.message.view">
</context:component-scan>
I tried creating the Application.class as follows.
package hello;
import java.util.Arrays;
import javax.jms.JMSException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ImportResource;
import org.springframework.jms.connection.SingleConnectionFactory;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.listener.DefaultMessageListenerContainer;
import com.ibm.mq.jms.MQQueue;
import com.ibm.mq.jms.MQQueueConnectionFactory;
#SpringBootApplication
//#ImportResource("classpath:context_receiver.xml")
public class Application {
#Autowired
public CustomException customException;
#Autowired
public MessageListener messageListener;
#Bean
public MQQueueConnectionFactory getMQconnectionfactory(){
MQQueueConnectionFactory mqconfactory=new MQQueueConnectionFactory();
try {
mqconfactory.setHostName("*******");
mqconfactory.setPort(*****);
mqconfactory.setChannel("**********");
mqconfactory.setQueueManager("********");
mqconfactory.setTransportType(1);
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return mqconfactory;
}
#Bean
public MQQueue getMQQueue(){
return new MQQueue();
}
#Bean
public DefaultMessageListenerContainer getDefaultMessageListenerContainer(){
DefaultMessageListenerContainer defmesliscont=new DefaultMessageListenerContainer();
defmesliscont.setConnectionFactory(getMQconnectionfactory());
defmesliscont.setSessionTransacted(true);
defmesliscont.setDestinationName("********");
defmesliscont.setExceptionListener(customException);
defmesliscont.setMessageListener(messageListener);
return defmesliscont;
}
#Bean
public SingleConnectionFactory getSingleConnectionFactory(){
SingleConnectionFactory singleConnectionFactory=new SingleConnectionFactory();
singleConnectionFactory.setTargetConnectionFactory(getMQconnectionfactory());
return singleConnectionFactory;
}
#Bean
public JmsTemplate getJmsTemplate(){
JmsTemplate jmsTemplate=new JmsTemplate();
jmsTemplate.setConnectionFactory(getSingleConnectionFactory());
jmsTemplate.setDefaultDestination(getMQQueue());
return jmsTemplate;
}
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
}
}
But am getting this error.

I have even tried importing the context.xml using #ImportResource. But that too is not working. Though i prefer configuring it through the Application.class.
Please tell me what am doing wrong. Thanks.

Answer 2

Upgrade you spring version to 4.1.5.RELEASE

Answer 3

I've got the same issue.
Looks like the problem is in incompatibility of EnableAutoConfiguration which is part of SpringBootApplication and https://github.com/spring-projects/spring-framework/blob/master/spring-core/src/main/java/org/springframework/core/annotation/AnnotationAttributes.java. EnableAutoConfiguration has exclude as Class [], but AnnotationAttributes expects String []. Most likely the versions are incompatible. I did not come up with solution yet though.

close idea
regenerate idea configuration files
$ mvn idea:clean
$ mvn idea:idea
reimport projects
run again in the idea
