实现类

 1 import org.springframework.core.task.TaskExecutor; 2  3 public class DemoBOImpl  4 { 5     // 线程池 6     @Resource(name = "taskExecutor") 7     private TaskExecutor taskExecutor; 8  9     @Override10     public void executeThread() throws Exception {11         // 线程池控制12         taskExecutor.execute(new DemoThread());13     }14 }

 

线程类

 1 public class DemoThread implements Runnable  2 { 3     public DemoThread() { 4     } 5  6     @Override 7     public void run() { 8         try { 9             // do things10         } catch (Exception e) {11         }12     }13 }
