单选框/复选框表示boolean 后台使用boolean接收

是否两个选项的单选框，后台使用boolean接收，value值使用 on/off或 1/0都可以转成boolean
<td>是否需要用户所在地信息</td>
			<td><input type="radio" name="needUserLocation" value="on" 
			<#if sysInfoCFG.needUserLocation> checked</#if> 
			> 是
			<input type="radio" name="needUserLocation" value="off" 
			<#if !sysInfoCFG.needUserLocation> checked</#if> 
			> 否
			</td>
将value改成其它值后台会转换报错
value="on2"
org.springframework.validation.BeanPropertyBindingResult: 1 errors

单个复选框也可以按boolean形式 只要value是
on/off或 1/0即可
<input type="checkbox" name="needUserLocation" value="1" 
			<#if sysInfoCFG.needUserLocation> checked</#if>
