我會使新線程在後臺工作。我試圖使用@Async和任務：註解驅動，但應用程序不工作。@Async和任務：註解驅動不起作用
根的context.xml
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
<context:component-scan base-package="com.cebul.jez.model, com.cebul.jez.service, com.cebul.jez.useful, com.cebul.jez.flows, com.cebul.jez.asynch" />
<task:annotation-driven executor="myExecutor" scheduler="myScheduler" />
AsyncWorker.java
@Service
public class AsyncWorker {
@Async
public void work() {
String threadName = Thread.currentThread().getName();
while(true)
{
System.out.println(" " + threadName + " work");
try {
Thread.sleep(30000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public void cancel() { Thread.currentThread().interrupt(); }
}
在控制器中，我使用它是這樣的：
@RequestMapping(value = {"/", "/home"})
public String home(Model model, HttpSession session){
asyncWorker.work();
//other code
}
如果我嘗試運行它，我有例外：

如果我刪除註釋驅動代碼complie並運行，但AsyncWorker任務BLOCK應用程序，所以AsyncWorker任務不會異步運行。
你能告訴我問題在哪裏嗎？
做你'AsyncWorker'實現任何接口
你有兩個選擇？你如何將它注入你的控制器？ – axtavt
我像這樣注入它：@Autowired \t private AsyncWorker asyncWorker; – user2987020
我試過了：public class AsyncWorker implements Worker，其中Worker：public interface Worker {public void work（）; public void cancel（）; } – user2987020
