if (XqZyfbFormBean._UPDATE.equals(formBean.getOperation())) {   
        XqZyfbModel pojo = new XqZyfbModel();   
        pojo.setPkid(formBean.getPkid());   
        pojo.setCustname(formBean.getCustname());   
        pojo.setPtid(formBean.getPtid());   
        pojo.setProdid(formBean.getProdid());   
        pojo.setPcname(formBean.getPcname());   
        pojo.setLen(formBean.getLen());   
        pojo.setSl(formBean.getSl());   
        pojo.setDj(formBean.getDj());   
        pojo.setJhadr(formBean.getJhadr());   
        pojo.setJhdt(formBean.getJhdt());   
        pojo.setNote(formBean.getNote());   
        pojo.setCmdeptid(new Integer(getUser(request).getCmdeptid()));   
        pojo.setLinkmanid(getUser(request).getLinkmanid());   
        generalService.saveXqResourcePublish(pojo);   
        return new ModelAndView("success", model);                  
    }   
       
    //显示明细   
    if (null!=formBean.getPkid()&&formBean.getPkid().intValue()>0)   
    {   
        XqZyfbModel pojo = generalService.selectXqResourceDetail(formBean.getPkid());   
        formBean.setPkid(pojo.getPkid());   
        formBean.setCustname(pojo.getCustname());   
        formBean.setPtid(pojo.getPtid());   
        formBean.setProdid(pojo.getProdid());   
        formBean.setPcname(pojo.getPcname());   
        formBean.setLen(pojo.getLen());   
        formBean.setSl(pojo.getSl());   
        formBean.setDj(pojo.getDj());   
        formBean.setJhadr(pojo.getJhadr());   
        formBean.setJhdt(pojo.getJhdt());   
        formBean.setNote(pojo.getNote());                  
    }   

对于如上代码,formBean中的属性与页面的属性一一对应,pojo与数据库table表中的字段一一对应,这样设计后却出现上面的干嘎代码,因为formBean中的大多数属性和pojo的大多数属性是相同的,但是有一些不同!能够有更简单的办法避免上面的尴尬的代码出现呢?本来想考虑使用反射,但是这么频繁的使用会否带来性能问题.
