model.setMrcID(entity.getMrcID());这个是什么意思

Question

在Controller中的
@ResponseBody
@RequestMapping(value="/update",method = RequestMethod.POST,produces = "application/json;charset=UTF-8")
public String update(RelatedCompany entity, HttpServletRequest request,
RedirectAttributes redirectAttributes) {
try{
AccountSession as = (AccountSession) WebUtils.getSessionAttribute(
request, SystemConst.LOGIN_USER_SESSION);

        entity.setUpdateUser(String.valueOf(as.getUserName()));
        RelatedCompany model = relatedCompanyService.getRelatedCompanyById(entity.getMrcID());

        model.setMrcID(entity.getMrcID());         

        relatedCompanyService.updateRelatedCompany(model);
        return  "success";
    } catch (Exception ex) {
        log.error(ex);
        return  "error! "+ex.getMessage();
    }
}

这个里面的entity.getMrcID()是获取的数据库的值还是页面上的值
model.setMrcID()应该是给页面赋值吧？新手不是很懂，求指点

Answer 1

entity.getMrcID()获取实体bean的id值
