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     @Override
10     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 things
10         } catch (Exception e) {
11         }
