SpringBootApplication
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}} 并应用yml文件 队列 端点 http// localhost9324 名称样本队列 我指定了一个本地主机端点因为我使用了ElasticMq 。 SQSConfig类是一个配置类以使SQS客户端作为spring bean可用。 package com.gkatzioura.sqstesting.config;import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.sqs.AmazonSQSClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** Created by gkatziourasemmanouil on 25/02/16.*/
Configuration
public class SQSConfig {Value(${queue.endpoint})private String endpoint;Value(${queue.name})private String queueName;Beanpublic AmazonSQSClient createSQSClient() {AmazonSQSClient amazonSQSClient new AmazonSQSClient(new BasicAWSCredentials(,));amazonSQSClient.setEndpoint(endpoint);amazonSQSClient.createQueue(queueName);return amazonSQSClient;}} SQSListener是实现JMS MessageListener接口的侦听器类。 package com.gkatzioura.sqstesting.listeners;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;/*** Created by gkatziourasemmanouil on 25/02/16.*/
Component
public class SQSListener implements MessageListener {private static final Logger LOGGER LoggerFactory.getLogger(SQSListener.class);public void onMessage(Message message) {TextMessage textMessage (TextMessage) message;try {LOGGER.info(Received message textMessage.getText());} catch (JMSException e) {LOGGER.error(Error processing message ,e);}}
} JMSSQSConfig类包含JmsTemplate和DefaultMessageListenerContainer的配置。 通过JMSSQSConfig类我们注册了JMS MessageListeners。 package com.gkatzioura.sqstesting.config;import com.amazon.sqs.javamessaging.SQSConnectionFactory;
import com.amazonaws.auth.*;
import com.gkatzioura.sqstesting.listeners.SQSListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.listener.DefaultMessageListenerContainer;/*** Created by gkatziourasemmanouil on 25/02/16.*/
Configuration
public class JMSSQSConfig {Value(${queue.endpoint})private String endpoint;Value(${queue.name})private String queueName;Autowiredprivate SQSListener sqsListener;Beanpublic DefaultMessageListenerContainer jmsListenerContainer() {SQSConnectionFactory sqsConnectionFactory SQSConnectionFactory.builder().withAWSCredentialsProvider(new DefaultAWSCredentialsProviderChain()).withEndpoint(endpoint).withAWSCredentialsProvider(awsCredentialsProvider).withNumberOfMessagesToPrefetch(10).build();DefaultMessageListenerContainer dmlc new DefaultMessageListenerContainer();dmlc.setConnectionFactory(sqsConnectionFactory);dmlc.setDestinationName(queueName);dmlc.setMessageListener(sqsListener);return dmlc;}Beanpublic JmsTemplate createJMSTemplate() {SQSConnectionFactory sqsConnectionFactory SQSConnectionFactory.builder().withAWSCredentialsProvider(awsCredentialsProvider).withEndpoint(endpoint).withNumberOfMessagesToPrefetch(10).build();JmsTemplate jmsTemplate new JmsTemplate(sqsConnectionFactory);jmsTemplate.setDefaultDestinationName(queueName);jmsTemplate.setDeliveryPersistent(false);return jmsTemplate;}private final AWSCredentialsProvider awsCredentialsProvider new AWSCredentialsProvider() {Overridepublic AWSCredentials getCredentials() {return new BasicAWSCredentials(, );}Overridepublic void refresh() {}};} MessageService是使用JMSTemplate以便将消息发送到队列的服务 package com.gkatzioura.sqstesting;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;/*** Created by gkatziourasemmanouil on 28/02/16.*/
Service
public class MessageService {Autowiredprivate JmsTemplate jmsTemplate;Value(${queue.name})private String queueName;private static final Logger LOGGER LoggerFactory.getLogger(MessageService.class);public void sendMessage(final String message) {jmsTemplate.send(queueName, new MessageCreator() {Overridepublic Message createMessage(Session session) throws JMSException {return session.createTextMessage(message);}});}} 最后但并非最不重要的一点是添加了控制器。 控制器将发布请求正文作为消息发送到队列。 package com.gkatzioura.sqstesting;import com.amazonaws.util.IOUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.InputStream;/*** Created by gkatziourasemmanouil on 24/02/16.*/
Controller
RequestMapping(/main)
public class MainController {Autowiredprivate MessageService messageService;RequestMapping(value /write,method RequestMethod.POST)public void write(HttpServletRequest servletRequest,HttpServletResponse servletResponse) throws IOException {InputStream inputStream servletRequest.getInputStream();String message IOUtils.toString(inputStream);messageService.sendMessage(message);}} 您可以在此处下载源代码。 翻译自: https://www.javacodegeeks.com/2016/02/aws-sqs-spring-jms-integration.htmlaws sqs
