背景
最近在对公司开发框架进行优化，框架内波及到多处入库的日志记录，例如登录日志/操作日志/拜访日志/业务执行日志，集成在业务代码中耦合度较高且占用业务操作执行工夫，所以筹备集成相干音讯队列进行代码解耦
计划布局
现有的成熟音讯队列组件十分多，例如RabbitMQ，ActiveMQ，Kafka等，思考到业务并发量不高且框架曾经利用于多个我的项目安稳运行，筹备提供基于Redis的音讯队列和集成ActiveMQ两种计划，Redis音讯队列的益处是无需额定装置部署存量我的项目可安稳适度但音讯无奈长久化可能失落，ActiveMQ解决方案成熟能够保障音讯长久化然而须要施行人员额定把握操作部署
对立设计
减少自定义配置指定音讯队列形式
system:
#音讯队列形式 redis/activemq
messageChannel: redis定义音讯传输对立模型
public class MessageModel {
private Class<? extends IMessageReceiver> handleClazz;
private String bodyContent;
private Class bodyClass;
private HashMap extraParam;
public MessageModel(){
extraParam = new HashMap();
}
public Class<? extends IMessageReceiver> getHandleClazz() {
return handleClazz;
}
public void setHandleClazz(Class<? extends IMessageReceiver> handleClazz) {
this.handleClazz = handleClazz;
}
public HashMap getExtraParam() {
return extraParam;
}
public void setExtraParam(HashMap extraParam) {
this.extraParam = extraParam;
}
public String getBodyContent() {
return bodyContent;
}
public void setBodyContent(String bodyContent) {
this.bodyContent = bodyContent;
}
public Class getBodyClass() {
return bodyClass;
}
public void setBodyClass(Class bodyClass) {
this.bodyClass = bodyClass;
}
}定义规范音讯解决接口
public interface IMessageReceiver {
void handleMessage(Object bodyObject, HashMap extraParam);
}定义对立对外发送音讯工具类
@Component
public class MessageUtil {
@Autowired
private SystemConfig systemConfig;
@Autowired
private RedisUtil redisUtil;
@Autowired
private JmsMessagingTemplate jmsMessagingTemplate;
public void sendMessage(Object messageBody, Class<? extends IMessageReceiver> handleClass, HashMap<String,Object> extraParam) {
MessageModel messageModel = new MessageModel();
messageModel.setHandleClazz(handleClass);
messageModel.setBodyClass(messageBody.getClass());
messageModel.setBodyContent(JSON.toJSONString(messageBody));
if (extraParam != null) {
for (String key:extraParam.keySet()) {
messageModel.getExtraParam().put(key,extraParam.get(key));
}
}
if(systemConfig.getMessageChannel().equals("redis")){
redisUtil.sendMessage("message", JSON.toJSON(messageModel));
}else{
jmsMessagingTemplate.convertAndSend("message",JSON.toJSONString(messageModel));
}
}
