activeMQ中调用DAO层的问题

Question

代码如下

 

public class ReceiveWorkSheetServiceBean implements ReceiveWorkSheetService,MessageListener {
 private WireWarningDAO wireWarningDAO;
        
   public WireWarningDAO getWireWarningDAO() {
  return wireWarningDAO;
 }

 public void setWireWarningDAO(WireWarningDAO wireWarningDAO) {
  this.wireWarningDAO = wireWarningDAO;
 }

 Logger log = Logger.getLogger(ReceiveWorkSheetServiceBean.class);
   
 // 消息监听函数
 public void onMessage(Message message) {
  try {
   log.info("[receive message]");
   if (message != null && !message.equals("")) {
    TextMessage msg = (TextMessage) message;
    String workSheet = msg.getText();
    System.out.println(workSheet);
    this.processWorkSheet(workSheet);
   }
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

 

我在收到数据的时候，发现wireWarningDAO的值为null，spring的配置文件里面也配置了

这完全是你spring注入的问题。
