1.在application-mvc中加入如下头文件内容：

xmlns:task="http://www.springframework.org/schema/task"
    
    http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd

2.在所需要的service或者controller类里面添加

@Resource(name = "taskExecutor")  
    private TaskExecutor taskExecutor;

3.测试

@Controller  
    public class IndexController {  
    int studentscount = 0;  
    @RequestMapping(value = "/index.html")  
        public ModelAndView goIndex() {  
            logBefore(logger, "列表Center");  
            ModelAndView mv = this.getModelAndView();  
                    taskExecutor.execute(new Runnable() {  
      
                    @Override  
                    public void run() {  
                        // TODO Auto-generated method stub  
                        // 得到所有学生人数  
                        try {  
                                              studentscount = coursesService.getStudentCount(pd);  
                        } catch (Exception e) {  
                            // TODO Auto-generated catch block  
                            e.printStackTrace();  
                        }  
      
                    }  
                });  
                      mv.addObject("studentscount", studentscount);  
                      mv.setViewName("common/index");  
                      return mv;  
    ｝
