Spring異步調用（新加spring 4.0的配置）

         隨着應用系統功能的不斷新增，而某些功能的實現對實時性要求並非那麼高，可是邏輯卻很複雜、執行比較耗時，好比涉及外部系統調用、多數據源等等；此時，咱們就但願可讓這些複雜的業務邏輯放在後臺執行，而前臺與用戶的交互能夠不用等待，從而提升用戶體驗。

異步代碼：

package com.digitalchina.lbs.serve.manager;
import java.util.Date;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Component;
@Component
public class AsynManager {
             
    @Async
    public void sleep(){
        Date date=new Date();
        System.out.println("====================================執行時間："+date);
        try {
            Thread.sleep(10000);
            System.out.println("====================================執行時間："+new Date());
                     
        } catch (Exception e) {
            // TODO: handle exception
        }
                 
    }
}

調用代碼：

@Service
public class LBSService {
    //測試
    @Autowired
    private AsynManager asynManager;
        
    public void asyn(CspServiceContext serviceContext){
        System.out.println("+++++++++++asynasynasynasyn+++++++++++++"+new Date());
        asynManager.sleep();
        System.out.println("++++++++++++++++++++++++"+new Date());
        // 向框架返回數據
        Response re = new Response(new Date());
        serviceContext.setResponseData(re);
        serviceContext.setResult(Result.SUCCESS_RESULT);
    }
}
