简单的异步操作处理；本用例使用的spring mvc框架，进行异步处理

首先设置web.xml:将是否支持异步设置为true

       
     
      SpringMVC
        
     
      org.springframework.web.servlet.DispatcherServlet
        
           
      
       contextConfigLocation
            
      
       classpath:spring-mvc.xml
         
        
     
      1
        
        
     
      true
     
    

spring-mvc.xml

service业务逻辑：

public interface ITaskService {    @Async    void asyncDemo();}

@Service@EnableAsyncpublic class TaskServiceImpl implements ITaskService {    @Async    @Override    public void asyncDemo() {        try {            System.out.println("异步执行开始:"+new Date());            Thread.sleep(10 * 1000);            System.out.println("异步执行完毕:"+new Date());        } catch (InterruptedException e) {            e.printStackTrace();        }    }}

controller调用：

@Controller@RequestMapping("/asyncTestDemo")public class AsyncTestDemo {    @Autowired    private ITaskService taskService;    @RequestMapping(params = "async")    @ResponseBody    public Map async(HttpServletRequest request) {        Map map = new HashMap();        map.put("code","201");        taskService.asyncDemo();        map.put("code","200");        return map;    }}
