推荐答案

您应该在Form对象中具有一个值，该值包含单选按钮的数据.在转发到JSP之前，您需要在Form中预先填充它(或者如果它始终默认为Form的值，则在Form的构造函数中将其默认).

You should have a value in your Form object that holds the data for your radio button. You'll need to pre-fill that in your Form before forwarding to the JSP (or default it in the Form's constructor if it will always default to that value).

Action.java

form.setRadioValue("123");

View.jsp

<html:radio property="radioValue" value="123" />  // <-- this radio will be checked
<html:radio property="radioValue" value="456" />  // <-- this radio will not be checked
