I am using spring-framework and spring-integration latest versions and just making POC application with spring integration but can't run this.
I have spring integration confing something like this.
<bean id="initUrlQ" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="initUrl.Q" />
</bean>
<int:channel id="initChannelProducerId" />
<jms:outbound-channel-adapter id="initOutboundId" channel="initChannelProducerId" connection-factory="padtoys.jms.cachedConnectionFactory"
destination="initUrlQ" />
<int:channel id="initChannelConsumerId" />
<jms:message-driven-channel-adapter id="initQListenerId" channel="initChannelConsumerId"
connection-factory="padtoys.jms.cachedConnectionFactory" destination="initUrlQ"
acknowledge="auto" concurrent-consumers="1" max-concurrent-consumers="1" />
<int:service-activator method="testSA" ref="testBean" input-channel="initChannelConsumerId" output-channel="nullChannel"/>
And my testBean java file looks like this.
public class TestBean implements ApplicationContextAware {
private ApplicationContext applicationContext;
#PostConstruct
public void afterInit(){
System.err.println("after init..!");
DirectChannel inChannel = applicationContext.getBean("initChannelProducerId", DirectChannel.class);
System.err.println("channel::" + inChannel);
inChannel.send(createMessage("This is test url!!", 0));
}
#Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
#ServiceActivator
public String testSA(){
System.err.println("inside service activator!!!");
return "this is test";
}
private Message<String> createMessage(final String url, final int depth) {
return MessageBuilder.withPayload(StringUtils.EMPTY)
.setHeader(MESSAGE_HEADERS.URL, url)
.setHeader(MESSAGE_HEADERS.DEPTH, depth).build();
}
}
And I am starting my application something like this.
#SuppressWarnings("resource") public static void main(String[] args) {
LOG.info("Trigerring process!");
new ClassPathXmlApplicationContext("/application-context.xml");
}
Please consider that I have declared testBean and padtoys.jms.cachedConnectionFactory in spring context xml.
PROBLEM :
When I start the application, getting below error
Caused by: org.springframework.messaging.MessageDeliveryException: Dispatcher has no subscribers for channel 'org.springframework.context.support.ClassPathXmlApplicationContext#5a1198c7.initChannelProducerId'.; nested exception is org.springframework.integration.MessageDispatchingException: Dispatcher has no subscribers

You must not perform messaging (send()) in a #PostConstruct method - it is too early in the application context lifecycle; the context is not yet ready to perform messaging.
See this answer for the proper place to perform messaging during startup.

I have a class that configures Cassandra database:
#Configuration
#EnableCassandraRepositories(basePackages = { BASE_PACKAGE })
public class CassandraConfig {
#Value("${spring.data.cassandra.contact-points}")
private String contactPoints;
#Value("${spring.data.cassandra.keyspace-name}")
private String keyspaceName;
#Value("${spring.data.cassandra.datacenter-name}")
private String datacenterName;
#Value("${spring.data.cassandra.port}")
private int port;
#Bean
public CqlSessionFactoryBean session() {
CqlSessionFactoryBean session = new CqlSessionFactoryBean();
session.setContactPoints(contactPoints);
session.setKeyspaceName(keyspaceName);
session.setLocalDatacenter(datacenterName);
session.setPort(port);
return session;
}
...
}

As I understand, it tries to connect to the database but it cannot, thus, it fails.
I tried different ways to exclude this class from context loading like #EnableAutoConfiguration(exclude = CassandraConfig.class) but then it fails with
java.lang.IllegalStateException: The following classes could not be excluded because they are not auto-configuration classes: com.myproject.test.config.CassandraConfig
Is there some advices or best practices how to solve this problem?
The error you're getting makes sense, CassandraConfig is not an autoconfiguration but a configuration class.
To exclude it you could use a Spring profile:
#Configuration
#Profile("!test")
public class CassandraConfig {
Then in your test class:
#SpringBootTest(properties = "spring.profiles.active=test")
class ApplicationTest {
I'm utilizing spring for about a year and everything was pretty obvious and simple until I faced spring integration. Ashamed, I can't create Outbound Gateway to send message to remote JMS (ActiveMQ) channel. Before integration I just used JmsTemplates and #JmsListeners directly, there were no problems at all.
What's the difference between request-destination and request-channel?
Here are my configs:
#Configuration
#EnableJms
public class JmsConfig {
...
#Value("${activemq.url}")
private String brokerUrl;
#Bean
public JmsTemplate jmsTemplate() {
JmsTemplate jmsTemplate = new JmsTemplate(queueConnectionFactory());
jmsTemplate.setDefaultDestinationName(bookingChannelName);
return jmsTemplate;
}
/*
#Bean(name = "bookingChannel")
public Queue activeMQQueue() {
return new ActiveMQQueue(bookingChannelName);
}
*/
#Bean
public JmsListenerContainerFactory jmsListenerContainerFactory() {
SimpleJmsListenerContainerFactory listenerFactory = new SimpleJmsListenerContainerFactory();
listenerFactory.setConnectionFactory(queueConnectionFactory());
return listenerFactory;
}
...
}
and an xml one, where all I've got in root beans element is:
<jms:outbound-gateway request-destination-name="reqDestination" request-channel="bookingChannel" />
Then, there is a gateway code:
#MessagingGateway
public interface BookingGateway<T> {
#Gateway
void bookTicket(T ticket);
}
And finally, here is how I use a gateway:
#Component
public class BookingGatewayImpl<T> {
#Autowired
private BookingGateway bookingGateway;
public <U> void bookTicket(T ticket, BiConsumer<T, U> onStatusReceived) {
bookingGateway.bookTicket(ticket); // second param is not utilized yet
}
}
And when ticket is about to be booked, I get:
send is not supported, because no request channel has been configured
Also, I am not able to uncomment ActiveMQQueue bean from the first listing because spring says it is not compatible with MessageChannel:
Bean named 'bookingChannel' must be of type [org.springframework.messaging.MessageChannel], but was actually of type [org.apache.activemq.command.ActiveMQQueue]
Why oh why should the destination be of MessageChannel type? What exactly am I doing wrong and how to get this ticket message to be sent?
bookingChannel is a MessageChannel between your MessagingGateway and the jms gateway. The destination is the AMQP Queue.
Use
#Gateway(requestChannel="bookingChannel")
#Bean(name = "bookingDestination")
public Queue activeMQQueue() {
return new ActiveMQQueue(bookingChannelName);
}
#Bean(name = "bookingChannel")
public MessageChannel bookingChannel() {
return new DirectChannel();
}
<jms:outbound-gateway request-destination-name="bookingDestination" request-channel="bookingChannel" />
Finally, came up with following configuration. Almost understood the way it's working now:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

According to the documentation spring batch admin is very easy to embed into the existing application. Simply copying web.xml and index.jsp then adding needed dependencies is enough getting it to work.
But if I want to use it in an existing spring boot project it getting worse. According to this example the configuration is a bit hacky but it works. UNTIL I try to use #EnableBatchProcessing annotation in my configuriton bean. Then I get the following exception.
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobBuilders' defined in class path resource [org/springframework/batch/core/configuration/annotation/SimpleBatchConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.batch.core.configuration.annotation.JobBuilderFactory org.springframework.batch.core.configuration.annotation.AbstractBatchConfiguration.jobBuilders() throws java.lang.Exception] threw exception; nested exception is java.lang.ClassCastException: org.springframework.batch.core.repository.support.JobRepositoryFactoryBean$$EnhancerBySpringCGLIB$$49fa0273 cannot be cast to org.springframework.batch.core.repository.JobRepository

My configuration is quite simple I have two configuration beans
#Configuration
#ImportResource({"classpath:/org/springframework/batch/admin/web/resources/servlet-config.xml",
"classpath:/org/springframework/batch/admin/web/resources/webapp-config.xml"})
public class BatchAdminConfiguration {
}
and
#Configuration
#EnableBatchProcessing
public class BatchImporterConfiguration {
}
When I remove #EnableBatchProcessing and try to create jobs with JobBuilderFactory and use #StepScope annotation I'm getting other ClassCastExceptions.
Now I'm using xml based configuration to create jobs, steps and other beans. It work well but I would actually preffer xml free configuration. Is there a way to easily integrate spring boot, spring batch and spring batch admin ?
Spring Batch Admin 2.0-BUILD-SNAPSHOT introduce a new Annoation #EnableBatchAdmin for easy to integrate with spring boot.
There is also a samples project https://github.com/spring-projects/spring-batch-admin-samples.
The short answer is that you won't want to use #EnableBatchProcessing with Spring Batch Admin. SBA provides a number of beans on a global scale that the #EnableBatchProcessing also provides. SBA 2.0 (currently in development) will probably fill the gaps between what is currently there and what #EnableBatchProcessing provides (specifically providing the JobBuilderFactory and StepBuilderFactory).
To get yourself running, you should be able to (I haven't tired this myself) configure in the META-INF/spring/batch/override/ directory a JobBuilderFactory and a StepBuilderFactory for global use. From there, you can use XML files in the META-INF/spring/batch/jobs directory that do nothing more than component scan for your #Configuration classes. However, leave off the #EnableBatchProcessing because of the duplication of beans.
For the record, this isn't an Spring Boot issue since #EnableBatchProcessing is a Spring Batch annotation, not a Boot one.
to complete the answer, here is the code to create the two beans once you disable the #EnableBatchProcessing annotation
#Autowired
JobRepository jobRepository;
#Autowired
PlatformTransactionManager transactionManager;
#Bean
public JobBuilderFactory jobBuilderFactory() {
return new JobBuilderFactory(jobRepository);
}
#Bean
public StepBuilderFactory stepBuilderFactory() {
return new StepBuilderFactory(jobRepository, transactionManager);
}
I've a working version here based on the same example (I forked the original one): https://github.com/vesperaba/spring-batch-admin-spring-boot.
I followed Michael Minella advice and I overwrote the SpringBatch property holder with a custom one.
I also added a job to check it's working now
This ClassCastException is caused by
classpath:/org/springframework/batch/admin/web/resources/servlet-config.xml
loading
META-INF/spring/batch/servlet/resources/resource-context.xml
which contains
<mvc:annotation-driven />
This conflicts with the mvc configuration in the Spring Java configuration class. The following class can be used to embed Spring Batch Admin within an existing application that uses Java configuration.

A single XML file is also required for the abstract base menu which is referenced elsewhere in the Spring Batch Admin project. This is required as abstract beans can not be provided from a Spring Java configuration.

Has anyone been through this?
In the server side, in my OSGi application, I'm exporting a service. Here's the spring file code:
<!-- RMI SERVICE EXPORT -->
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
<property name="serviceName" value="IntegrationRemoteService" />
<property name="service" ref="integrationExecutor" />
<property name="serviceInterface" value="my.package.services.IntegrationService" />
<property name="registryPort" value="$system{integration.port}" />
</bean>
<!-- INTEGRATION EXECUTOR -->
<bean id="integrationExecutor" class="my.package.engine.IntegrationServiceExecutor">
<property name="integrationServiceImpl" ref="integrationEngine" />
</bean>
My IntegrationServiceExecutor class extends the IntegrationService interface and implements the method:
public class IntegrationServiceExecutor implements IntegrationService {
...
#Override
public GenericResult dispatch(int serviceCode, AdapterHeader adapterHeader, AdapterInfo adapterInfo) {
The IntegrationService interface is defined in another component and this same component is used in my .war in the client side. In that component, I also have the implementation of the remote request called through my .war
...
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.remoting.rmi.RmiProxyFactoryBean;
...
public class GenericRmiFactory implements RemoteConnectionFactory {
private ProxyFactory proxyFactory;
public GenericRmiFactory(ServerTransport transport) throws ClassCastException, IllegalFormatException {
RmiServerTransport rmiTransport = (RmiServerTransport) transport;
RmiProxyFactoryBean rmiProxyFactoryBean = new RmiProxyFactoryBean();
rmiProxyFactoryBean.setLookupStubOnStartup( false );
rmiProxyFactoryBean.setCacheStub( false );
rmiProxyFactoryBean.setRefreshStubOnConnectFailure( true );
rmiProxyFactoryBean.setServiceUrl(String.format("rmi://%s:%s/%s", rmiTransport.getHostname(), rmiTransport.getPort(), rmiTransport.getServiceName() ));
rmiProxyFactoryBean.setServiceInterface(rmiTransport.getRemoteInterface());
rmiProxyFactoryBean.afterPropertiesSet();
this.proxyFactory = new ProxyFactory(rmiTransport.getRemoteInterface(), rmiProxyFactoryBean);
}
private ProxyFactory getproxyFactory() {
return proxyFactory;
}
#Override
public Object getRemoteService() {
return getproxyFactory().getProxy();
}
}
I call the remote service in this way:
...
IntegrationService integrationService = (IntegrationService) getGenericRemoteFactory().getRemoteService();
integrationService.dispatch(myInt, myAdapterHeader, myAdapterInfo);
...
This last statement throws the exception:
Invocation of method [public abstract my.package.result.GenericResult my.package.services.IntegrationService.dispatch(int,my.package.beans.AdapterHeader,my.package.beans.AdapterInfo)] failed in RMI service [rmi://127.0.0.1:2260/IntegrationRemoteService]; nested exception is java.lang.NoSuchMethodException: $Proxy205.dispatch(int, my.package.beans.AdapterHeader, my.package.beans.AdapterInfo)
Is there something I'm missing here?
Thanks in advance,
Karen
I've seen this before. You have to add 'throws RemoteException' to your interface method. The client throws a NoSuchMethodException, but it's really complaining about the lack of RemoteException.
I'm trying to use Freemarker for template emails in my web-app on JBoss 5.1 web-app server.
mail-context-xml:
<bean id="freemarkerConfiguration"
class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean">
<property name="templateLoaderPath" value="/WEB-INF/templates" />
</bean>
<bean id="registrationMailService" class="com.epam.darts.webapp.utils.RegistrationMailService">
<property name="configuration" ref="freemarkerConfiguration" />
<property name="mailSender" ref="mailSender" />
</bean>
RegistrationMailService.java:
public class RegistrationMailService {
private JavaMailSender mailSender;
private Configuration configuration;
public void sendConfirmationEmail(final User user) {
MimeMessage message = this.mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message);
try {
helper.setFrom(user.getLogin());
helper.setTo(user.getLogin());
helper.setSubject(user.getLogin());
Map<String, Object> model = new HashMap<String, Object>();
model.put("user", user);
String sendText = FreeMarkerTemplateUtils.processTemplateIntoString(
this.configuration.getTemplate("regisstration_mail.html"), model);
helper.setText(sendText, true);
this.mailSender.send(helper.getMimeMessage());
}
catch(MessagingException e) {
e.printStackTrace();
}
}
public void setMailSender(final JavaMailSender mailSender) {
this.mailSender = mailSender;
}
public void setConfiguration(final Configuration configuration) {
this.configuration = configuration;
}
}
maven depandency for freemarker:
<dependency>
<groupId>freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.9</version>
</dependency>
First time it works good. But if I try to redeploy my app (mvn clean package jboss:hard-deploy) I got error
18:17:46,839 ERROR [ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registrationMailService' defined in
ServletContext resource [/WEB-INF/spring/spring-mail.xml]: Initialization of bean failed; nested exception is org.springfram
ework.beans.ConversionNotSupportedException: Failed to convert property value of type 'freemarker.template.Configuration' to
required type 'freemarker.template.Configuration' for property 'configuration'; nested exception is java.lang.IllegalStateE
xception: Cannot convert value of type [freemarker.template.Configuration] to required type [freemarker.template.Configurati
on] for property 'configuration': no matching editors or conversion strategy found
May be problem is in class-loader, but i dont know how fix it.
It looks like you have two copies of freemarker's JAR file in your classpath. You need to find them, and narrow it down to one.
