我在PostgreSQL DB中有一个表,如下所示:

 Client | Rate | StartDate|EndDate     
 A      | 1000 | 2005-1-1 |2005-12-31
 A      | 2000 | 2006-1-1 |2006-12-31
 A      | 3000 | 2007-1-1 |2007-12-31  
 B      | 5000 | 2006-1-1 |2006-12-31  
 B      | 8000 | 2008-1-1 |2008-12-31  
 C      | 2000 | 2006-1-1 |2006-12-31  

如何得到这个结果？

 Client | Rate | StartDate|EndDate    |Pre Rate | Pre StartDate |Pre EndDate    
 A      | 1000 | 2005-1-1 |2005-12-31 |         |               |             
 A      | 2000 | 2006-1-1 |2006-12-31 | 1000    | 2005-1-1      |2005-12-31            
 A      | 3000 | …

我刚刚将我的Eclipse从Galileo更新为Juno.我创建了一个新的工作区并导入了一个基于Java Spring MVC的项目.当我打开它时,它开始"加载描述符",然后弹出一条错误消息:在"为mta_pfm加载描述符"期间发生内部错误.如果我使用Galileo打开它,则没有错误.我试图在Juno中禁用XML文件的验证,但它不起作用.我现在不知道如何修复它.请帮忙.谢谢

Spring MVC应用程序需要执行一个需要几分钟的密集计算工作.客户端希望以异步方式运行此作业.但是在我对方法启用@Async注释后(参见代码1)并获得错误(参见代码2).我的web.xml和web-appliaiton-context.xml也在下面给出.我试图找到解决方法来解决这个问题,但失败了.请帮忙.

代码1:

@Service
public class AsyncServiceImpl implements AsyncServiceInt{

    protected int pertArrSize = 1000;
    @Autowired
    protected TblvDao tblvDao1 = null;

    @Override
    @Async
    public void startSlowProcess(Integer scenarioId) throws SecurityException, IllegalArgumentException, IOException, ClassNotFoundException, NoSuchFieldException, IllegalAccessException {
        batchUpdateSummaryPertSim(scenarioId);

    }

    public void batchUpdateSummaryPertSim(Integer scenarioId) throws SecurityException, IllegalArgumentException, IOException, ClassNotFoundException, NoSuchFieldException, IllegalAccessException
    {
        double[] summaryArry = new double[pertArrSize];
        summaryArry = summaryPertSim_env(scenarioId, summaryArry);
    }
