@Autowired在可运行内部无法正常工作

Question

我有一个可运行的任务，正在尝试自动接线，但是当我这样做时，该任务无法运行。当我为可运行范围外的田地自动接线时，它工作正常。为什么会这样呢？除了在内部自动装配外，是否还有其他更清洁的方法可以在可运行内部获取自动装配字段的新实例？

这是我的可运行方法

Runnable task = new Runnable() {

                @Autowired
                ICruxPanelClientService CruxPanelClientService;

                public void run (){
            CruxPanelClientService.setCruxWebServiceBaseURL("http://10.41.181.23:8080");
            CronCruxModel m = new CronCruxModel();
            m = model1.get(model_var);
            System.out.println("EXECUTING");
            System.out.println(m.getService_status() + " ---------EXEexecution");
            System.out.println(m.getCat_name() + "Executing Name ");
        //  time = m.getService_time();
            UpdateCategoryRequest updateCategoryRequest = new UpdateCategoryRequest();
            CategoryModel categoryModel = new CategoryModel();
            categoryModel.setColor(m.getCat_color());
            categoryModel.setIcon(m.getCat_icon());
            categoryModel.setIconWhite(m.getCat_icon_white());
            categoryModel.setName(m.getCat_name());
            categoryModel.setId(m.getCat_id());
            categoryModel.setKey(m.getCat_catkey());
            categoryModel.setIndexOrder(m.getCat_indexOrder());
            updateCategoryRequest.setCategory(categoryModel);
            CruxPanelClientService.updateCategory(updateCategoryRequest);
            GetServiceDataIdByCategoryIdRequest request1 = new GetServiceDataIdByCategoryIdRequest();    
            request1.setId(m.getCat_id());
            GetServiceDataIdByCategoryIdResponse response1 = CruxPanelClientService.getServiceDataIdByCategoryId(request1);
            ArrayList<ServiceModel> service = new ArrayList<ServiceModel>();
            service = response1.getServiceModels();

            JSONArray json = new JSONArray();
            if(m.getService_order_succ_msg()==null)
            {
                json = new JSONArray();
            }
            else {

                 json = new JSONArray(m.getService_order_succ_msg());
            }
            String message = m.getService_order_succ_msg();

            for (int j=0;j<service.size();j++)
            {   
                UpdateServiceMasterRequest req = new UpdateServiceMasterRequest();
                ServiceModel s = new ServiceModel();
                s=service.get(j);
                ;
                JSONObject obj = new JSONObject();

                if(json.length()==0 ) 
                {
                    String ms = null;
                    s.setOrderSuccessMessage(ms);
                    req.setServiceModel(s);

                }

                else {

                    String message1 = json.get(j).toString();

                    if(message1.equals(null) || message1.equals("")) {
                        String ms = null;
                        s.setOrderSuccessMessage(ms);
                        req.setServiceModel(s);

                    }
                    else {
                        s.setOrderSuccessMessage(message1);

                        req.setServiceModel(s);

                    }
                }
                CruxPanelClientService.updateServiceMaster(req);

            }
            m.setService_status("executed");
            UpdateCronCruxRequest q = new UpdateCronCruxRequest();
            q.setCronCruxModel(m);
            CruxPanelClientService.updateCronCrux(q);

                }
            };`

@Autowire不能用于匿名类（因为您调用的是new，而不是 Spring ），您可以在外部类中自动装配一个字段，然后在您的Runnable.

或者创建Runnable一个完整的类（不是匿名的）并使其成为一个bean（和自动装配，例如使用id）

问题是spring无法控制可运行对象的创建。有两种可能的解决方案：

1. 将可运行的创建放入某些服务，存储库，控制器，组件或spring曾经处理的内容：

例：

@Service
public class SomeService {

    @Autowired
    private ICruxPanelClientService cruxPanelClientService;

    public Runnable newRunnable() {

        return new Runnable() {

            public void run() {
                cruxPanelClientService <- will be visible here and injected
            }
        }
    }

}

2. 使用原型范围创建可运行为Bean

例：

@Configuration
public class Runnableconfiguration {

    @Bean
    @Scope("prototype")
    public Runnable newRunnbale(final ICruxPanelClientService cruxPanelClientService) {
        return new Runnable() {
            public void run() {
                cruxPanelClientService <- will be visible here
            }
        }
    }
}
