Couldn't pass the #bean value to another class through Autowiring

I am new to spring. So I couldn't figure out what issue is there in the below code. I have two classes. I am defining a #Bean Channel and am autowiring that bean in the next class. I am using annotation for autowiring. When I try " System.out.println(externalChannel.toString());" am getting null values and the exception null pointer exception is thrown.
#Configuration
public class MessagingConfig
{
#Value("${service.name}")
private String queueName; // NOSONAR
#Value("${${user}")
private String schema;
#Value("${Owner}")
private String owner;
#Bean
public Channel externalChannel()
{
EventsProvider eventsProvider = new EventsProvider();
eventsProvider.setOwner(owner);
System.out.println("-------Cost And Events Channel-------"+eventsProvider.getEventsChannel());
return eventsProvider.getEventsChannel();
}
}
And Another class is
#Component
#LoggedService
#Monitored(useActualType = true)
public class MessagePublish {
#Autowired
private MessagingService messageService;
#Autowired
private Channel externalChannel;
public void publishTPSMessage(SourceTransaction sourceTransaction)
{
TPSEvent event = new TPSEvent(ContextHolder.getContextId(), new Date(), GuidUtils.generateGuid(),sourceTransaction);
Message<TPSEvent> message = new Message<TPSEvent>(event);
message.getHeader().setMessageType(TPSEvent.class.getName());
message.getHeader().setPayloadEncodingType(SystemCodecs.XML.name());
System.out.println(message.toString());
System.out.println(externalChannel.toString());
messageService.publish(externalChannel, message);
}
}
More Info
public Channel getEventsChannel() {
return Channel.builder()
.setName("necessarySources")
.setConnectionName("defaultConnection")
.setType(ChannelType.Topic)
.setConnectionData(AqSqlConnectionData.buildString(this.owner, "Safi"))
.setSubscriberNames(new String[]{"Safi_Autowire"})
.build();
}
Main Class
public class TPSHandler {
public static void main(String[] args) {
BatchExport batchExportBean=getBatchExportASJAXBElement();
System.out.println(" batchExportBean Trans Description : " + batchExportBean.getDueDate());
for(Pay pay :batchExportBean.getPay()) {
SourceTransaction sourceTransaction=mapPayBatchToSourceTransaction(pay,batchExportBean);
String sourceTraString = getSourceTransactionASXML(sourceTransaction);
System.out.println(" sourceTraString : \n" + sourceTraString);
MessagePublish messagePublish= new MessagePublish();
//SourceTransaction sourceTransaction= new SourceTransaction();
messagePublish.publishTPSMessage(sourceTransaction);

What is the issue over here? Can anybody help me with this? what exactly I am missing here?

You need to initialize a Spring context at the start of your application when you do not create a servlet / run as a Server.

Looks like you miss the spring-aspects.jar as a dependency in your Project.
Add to your pom:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
</dependency>

Try to add this spring-aspects dependency like this:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
</dependency>

Concurrent testing with TestNG and Spring Transaction

I have a service class, the service class is annotated with #Transactional(propagation = Propagation.REQUIRES_NEW) and its public method is defined in an interface:
public interface UniqueKeyGeneratorService {
void initializeUniqueKeys(Entity entity);
}
#Transactional(propagation = Propagation.REQUIRES_NEW)
public final class KeyGeneratorServiceImpl implements UniqueKeyGeneratorService, DisposableBean {
private final UniqueKeyGeneratorStrategy strategy;
private KeyGeneratorServiceImpl(final UniqueKeyGeneratorStrategy strategy) {
this.strategy = strategy;
}
#Override
public void initializeUniqueKeys(final Entity entity) {
// ... the business logic
}
// ... some private methods
#Override
public void destroy() {
strategy.destroy();
}
}
And the bean is created using a FactoryBean (to initialize the strategy).
I want to test the service, so I configured an embedded H2 database, defined a connection pool using Apache Commons DBCP and write proper test code as:
#ContextConfiguration("/path/to/xml/config/file.xml")
#Transactional
public class TestUniqueKeyGeneratorService extends AbstractTransactionalTestNGSpringContextTests {
#Autowired
private UniqueKeyGeneratorService service;
#Test
#Rollback(false)
public void testCodeGeneration() {
final Department department1 = new Department();
department1.setName("Abcd");
service.initializeUniqueKeys(department1);
final String code = department1.getCode();
Assert.assertNotNull(code);
}
// ... some more test methods
}
and have

any idea how to handle this exception?
p.s. I reviewed H2 documentations, and it supports multiple connections in embedded mode.

Spring autowire issue

i am running a unit tests and uses a Service class to perform some business logic. however, the unit tests fails saying that the service class is null dispite setting up the Autorwire annotations for it.
below is my unit test:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/FreedomSpring-servlet.xml" })
public class UserControllerTest
{
private UserController controller;
#Inject
private ApplicationContext applicationContext;
private String jsonUser = "{ \"username\":\"jonneymendoza\",\"emailAddress\":\"jon#google.com\", \"password\":\"12345678\",\"firstName\":\"jono\", \"surname\":\"richy\", \"country\":\"united kingdom\",\"bio\":\"Bio stuff goes here about the user. where he comes from etc etc. all is well. lets go go go\" }";
#Before
public void setup()
{
controller = new UserController();
assertNotNull(applicationContext);
}
#Test
public void testCreateNewAccount()
{
ResponseEntity<String> response = controller
.createNewAccount(new HttpEntity<String>(jsonUser));
assertEquals(HttpStatus.CREATED, response.getStatusCode());
}
}
Here is the controller i am testing
#Controller
public class UserController
{
#Autowired
private UserService userService;
#RequestMapping(value = "/user", method = RequestMethod.PUT, consumes = "application/json")
public ResponseEntity<String>createNewAccount(HttpEntity<String>request)
{
userService.registerNewUser( JSONObject.fromObject(request.getBody())); //fails here
return new ResponseEntity<String>(null, responseHeaders, HttpStatus.CREATED);
}
}
The service class:
#Service("UserService")
#Transactional
public class UserService implements UserServiceInterface
{
#Override
public void registerNewUser(JSONObject user) throws InvalidDataException, JSONException
{
// parse json object to a User object
User newUser = parseJsonObject(user);
UserDao userDao = new UserDao();
userDao.addNewUser(newUser);
}
}

You need to inject (with some annotation) or retreive userController from the applicationContext so that Spring magic (i.e. injection or userService in your case) works.
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/FreedomSpring-servlet.xml" })
public class UserControllerTest {
#Autowired
private UserController userController;
#Inject
private ApplicationContext applicationContext;
private String jsonUser = "{ \"username\":\"jonneymendoza\",\"emailAddress\":\"jon#google.com\", \"password\":\"12345678\",\"firstName\":\"jono\", \"surname\":\"richy\", \"country\":\"united kingdom\",\"bio\":\"Bio stuff goes here about the user. where he comes from etc etc. all is well. lets go go go\" }";
#Before
public void setup() {
assertNotNull(applicationContext);
assertNotNull(userController);
}
