java - Spring运行独立线程

Question

我正在运行带有 spring security 3.2 的 v4 Spring mvc 应用程序我正在尝试从 Controller 运行独立线程

@Controller
    public class C1{
         @AutoWired
         C2 c2;

         @RequestMappting("/")
         public String home(){
            c2.run();
            System.out.println("something");
            return "home";
         }
    }
}

@Component
@Scope
public class C2 extends Thread{
  @Override
  public void run(){
    while(true){
       System.out.println("random stuff");
    }
  }
}

当我运行此代码时，它陷入c2.run(); 下一行不执行；我在这里想要实现的是连续打印随机内容并渲染 home.jsp 页面
我做错了什么，如何解决这个问题？？？

使用Spring框架时不需要直接使用Threads。它有一个很棒的Task Execution and Scheduling应该使用的抽象。这样你想要的就可以实现。

@Controller
public class C1{
     @AutoWired
     C2 c2;

     @RequestMappting("/")
     public String home(){
        c2.run();
        System.out.println("something");
        return "home";
     }        
}

@Component
@Scope
public class C2{

  @Async
  public void run(){
    while(true){
       System.out.println("random stuff");
    }
  }
}

@Configuration
@EnableAsync
public class AppConfig implements AsyncConfigurer {

 @Override
 public Executor getAsyncExecutor() {
     ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
     executor.setCorePoolSize(7);
     executor.setMaxPoolSize(42);
     executor.setQueueCapacity(11);
     executor.setThreadNamePrefix("MyExecutor-");
     executor.initialize();
     return executor;
 }

 @Override
 public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
     return MyAsyncUncaughtExceptionHandler();
 }

}
