添加数据时候自动更新时间,注意添加数据时,要设置最大主键 时间的工具类:CommonUtil 人的工具类: ContextUtil ScmCompanyAccount scmCompanyAccount=new ScmCompanyAccount(); //设置最大主键 scmCompanyAccount.setAccountId(new Long(CTCSequenceUtil.genEntitySequenceNo(ScmCompanyAccount.class))); //设置默认登录人和登录时间 long loginId = ContextUtil.getUserView().getLoginId(); scmCompanyAccount.setCreateOper(loginId); scmCompanyAccount.setCreateDate(CommonUtil.getDateTime()); dataWrap.setData(scmCompanyAccount); responseData.setAjaxDataWrap("dataWrap", dataWrap); 保存时更新数据,该判断写在保存方法中 if (updateList != null && updateList.size()>0){ for(ScmCompanyAccount entity:updateList){ //设置默认登录人和登录时间 long loginId = ContextUtil.getUserView().getLoginId(); entity.setModifyOper(loginId); entity.setModifyDate(CommonUtil.getDateTime()); } JPAUtil.update(updateList);
