基于Spring的异步系统实现方案

一般的实现方案

发送异步消息所使用的工具类：

     private static JmsTemplate jmsTemplate;
     private static Destination sendMailDestination;
     private static Destination LoginLogDestination;
     private static Destination normalLogDestination;
     private static Destination pushNotificationDestination;
     public static void log(String type,String operate){
         if(!SystemConfigFromDB.getBoolean(SystemConfigFromDB.NEED_NORMAL_LOG)){
             return;
         }
         try{
             User user = (User) SecurityUtils.getSubject().getSession().getAttribute("loginUser");
             if(user==null){

             //AsycWorkFactory.sendMessage(message, AsycWork.NORMAL_LOG);
             jmsTemplate.send(normalLogDestination, new MessageCreator() {
                 @Override
                 public Message createMessage(Session session) throws JMSException {

         }
         try{
             final ActiveMQMapMessage message = new ActiveMQMapMessage();
             message.setString("address", address);
             message.setString("title", title);
             message.setString("content", content);
             //AsycWorkFactory.sendMessage(message, AsycWork.EMAIL);
             jmsTemplate.send(sendMailDestination, new MessageCreator() {
                 @Override

     }
     public static void loginLog(String uid,String ip,Date date){

         }
         try{
             final ActiveMQMapMessage message = new ActiveMQMapMessage();
             message.setString("uid", uid);
             message.setString("ip", ip);
             message.setString("date", DateUtils.formatDateTime(date, "yyyy-MM-dd HH:mm:ss"));
             //AsycWorkFactory.sendMessage(message, AsycWork.LOGIN_LOG);
             jmsTemplate.send(LoginLogDestination, new MessageCreator() {
                 @Override
                 public Message createMessage(Session session) throws JMSException {
                     return message;
                 }
             });
         }catch (Exception e) {

         }
     }
     public static void pushNotification(String id,String content){
         if(!SystemConfigFromDB.getBoolean(SystemConfigFromDB.NEED_LOG_CLIENTUSER_LOGINLOG)){
             return;
         }
         try{
             final ActiveMQMapMessage message = new ActiveMQMapMessage();
             message.setString("id", id);
             message.setString("content", content);
             jmsTemplate.send(normalLogDestination, new MessageCreator() {
                 @Override
                 public Message createMessage(Session session) throws JMSException {
                     return message;
                 }
             });
         }catch (Exception e) {
             log.error("消息推送出错！",e);
         }
     }
     @Autowired
     public void setJmsTemplate(JmsTemplate jmsTemplate) {
         AsyncUtils.jmsTemplate = jmsTemplate;
     }
     @Autowired
     @Qualifier("sendMailDestination")
     public void setSendMailDestination(Destination sendMailDestination) {
         AsyncUtils.sendMailDestination = sendMailDestination;
     }
     @Autowired
     @Qualifier("LoginLogDestination")
     public void setLoginLogDestination(Destination loginLogDestination) {
         LoginLogDestination = loginLogDestination;
     }
     @Autowired
     @Qualifier("normalLogDestination")
     public void setNormalLogDestination(Destination normalLogDestination) {
         AsyncUtils.normalLogDestination = normalLogDestination;
     }
     @Autowired
     @Qualifier("pushNotificationDestination")
     public void setPushNotificationDestination(
             Destination pushNotificationDestination) {
         AsyncUtils.pushNotificationDestination = pushNotificationDestination;
     }
 }

监听异步消息的监听器类（可以给每个类型的消息设定不同的监听器）：

 @Component
 public class EmailListener implements MessageListener {
     private static Logger log = LoggerFactory.getLogger(EmailListener.class);
     @Override
     public void onMessage(Message message) {
         ActiveMQMapMessage msg = (ActiveMQMapMessage) message;
         try {
             String address = msg.getString("address");
             String title = msg.getString("title");
             String content = msg.getString("content");
             Constants.sendMail(address, title, content);
         } catch (Exception e) {
             log.error("异步邮件发送异常", e);
         }
     }
 }

使用方式:

//异步发送邮件
AsyncUtils.sendMail("邮件地址","主题","内容");
//即可
