My aim: i have multiple jobs(Processes) running parallely (seperate threads). i want to implement messaging so that each process can send message(if required) to rabbitmq Server. now i have this
@Configuration
public class SenderConfiguration {
String content = "";
String host = "";
String port = "";
String userName = "";
String password = "";
String queueName = "";
InputStream input = null;
public SenderConfiguration() {
init();
}
private void init() {
Properties prop = new Properties();
try {
input = new FileInputStream("R.CONFIGURATION_FILE_PATH");
host = prop.getProperty("messaging.host");
port = prop.getProperty("messaging.port");
userName = prop.getProperty("messaging.userName");
password = prop.getProperty("messaging.password");
queueName = prop.getProperty("messaging.queue");
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
if (input != null) {
try {
input.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
@Bean
public RabbitTemplate rabbitTemplate() {
RabbitTemplate template = new RabbitTemplate(connectionFactory());
template.setRoutingKey(this.queueName);
return template;
}
@Bean
public ConnectionFactory connectionFactory() {
CachingConnectionFactory connectionFactory = new CachingConnectionFactory(
this.host);
connectionFactory.setUsername(userName);
connectionFactory.setPassword(password);
return connectionFactory;
}
@Bean
public ScheduledProducer scheduledProducer() {
return new ScheduledProducer();
}
@Bean
public BeanPostProcessor postProcessor() {
return new ScheduledAnnotationBeanPostProcessor();
}
static class ScheduledProducer {
@Autowired
private volatile RabbitTemplate rabbitTemplate;
private final AtomicInteger counter = new AtomicInteger();
@Scheduled(fixedRate = 1000)
public void sendMessage(String message) {
rabbitTemplate.convertAndSend("Roxy " + counter.incrementAndGet());
}
}
}
and to call this from one of my operation
new AnnotationConfigApplicationContext(SenderConfiguration.class);
shall i make it abstract class and my every operation /process should extend it ? what would be best approach ? and can i make above process any better?
