比如：我们在做CRM系统的时候，CRM系统中的字段是根据用户自己的需求来自己设定的，我们首先提供一些，必须的几个常用的字段，特别的用户是根据自己公司的建制有自己需求的字段，那我们就要在设计数据库的时候提前预留出一些字段大概也就是20个左右的字段，让客户使用。那我们针对这个预留的字段怎么获取值啊？比如用户在界面上把预留字段strFiled1设置成“公司的文化”这个字段，那我们该如何处理界面上显示的这个字段所对应的值那？这个预留的字段的名（strField1）会不会被修改成（companyWenHua）这个名字啊？估计大家都会有这样的疑问，我刚开始也是怀揣这个疑问。下面直接上代码：

在上述的源代码中：
List<CompanyColumnDefinition> companyColumns = CompanyColumnDefinitionLocalServiceUtil.searchByTableName(companyId, TableConst.CRM_Customer, true);
这一句话是不是看起来很简单，只看名字估计大家都能知道什么意思，不就是通过数据库的名字找到数据库中的所有的列吗？大家用脚指头想想，也是这个意思，第一个参数代表是公司的id。第二个参数表的名字。是你真聪明，但是后台他做的事情很多的。这个等我看过源代码再给大家补充上去，我只是猜测，不敢断言。通过注解可以实现通过数据库的表的名字能找到列的名字。
if (columnName.equals("dateField1")){
dynamicValue.put(columnName, DateUtil.formatDateNoHour(customer.getDateField1()));
｝这一行代码的意思是不是解释了大家的疑问。它是没有改变列的名字，只是修改了列的对应的内容。
