分享struts中的一个异常
我在做struts项目出现了这个异常，希望各位看看除了什么问题？
javax.servlet.ServletException: DispatchMapping[/Vehicle] does not define a handler property
在配置DynaForm时是这样配置的：
<struts-config>
<data-sources />
<form-beans>
<form-bean name="vehicleDynaForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="category" type="java.lang.String"></form-property>
<form-property name="model" type="java.lang.String"></form-property>
<form-property name="no" type="java.lang.String"></form-property>
<form-property name="price" type="java.lang.double"></form-property>
</form-bean>
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings >
<action path="/Vehicle" name="vehicleDynaForm" type="y2.ssh.vehicle.web.action.VehicleAction" >
<forward name="vehicleInfo" path="/vehicleInfo.jsp"/>
</action>
</action-mappings>
<message-resources parameter="com.vehicle.struts.ApplicationResources" />
</struts-config>

function check(){
if(document.getElementsByName["ispublic"].checked==true)
{
document.getElementsByName["ispublic"].value='是';
alert('ok');
}else
{
document.getElementsByName["ispublic"].value='否';
alert('no');
}
}
我用这个语句想给checkbox赋值，但是在action中怎么获取的总是on，而我给的值怎么就没有赋上了!希望各位帮帮我吧！谢谢了！

有两种方式：一是写过滤器，还有就是写个类来继承struts里的一个类来处理，既然你在学struts，那就讨论第二种。
写个类继承自RequestProcessor。
package com.struts;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.RequestProcessor;
public class Myrequest extends RequestProcessor()
{
@Override
public void process(HttpServletRequest arg0, HttpServletResponse arg1)
throws IOException, ServletException {
arg0.setCharacterEncoding("utf-8");
super.process(arg0, arg1);
}
}
然后再struts.config.xml里配置下
<controller processorClass="com.struts.MyRequest"></controller>
注意配置信息要紧贴配在<message-resources />上面，而不能把顺序打乱了

[Quote=引用 10 楼 zhj92lxs 的回复:]
<action path="/Vehicle" name="vehicleDynaForm" type="y2.ssh.vehicle.web.action.VehicleAction" parameter="method" >
<forward name="vehicleInfo" path="/vehicleInfo.jsp"/>
</action>
<form action="Vehicle.do?method=doAdd" method="post">
[/Quote]
正解！

我VehicleAction中的代码是：
package y2.ssh.vehicle.web.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.DynaActionForm;
import org.apache.struts.actions.DispatchAction;
import y2.ssh.vechile.biz.impl.VehicleBizImpl;
import y2.ssh.vehicle.biz.VehicleBiz;
import y2.ssh.vehicle.entity.Vehicle;
/**
* MyEclipse Struts
* Creation date: 10-30-2008
*
* XDoclet definition:
* @struts.action validate="true"
*/
public class VehicleAction extends DispatchAction {
/*
* Generated Methods
*/
/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
private VehicleBiz biz=new VehicleBizImpl();
public ActionForward doAdd(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
DynaActionForm vehicleForm=(DynaActionForm)form;
Vehicle vehicle=new Vehicle();
vehicle.setCategory(vehicleForm.getString("category"));
vehicle.setModel(vehicleForm.getString("model"));
vehicle.setNo(vehicleForm.getString("no"));
vehicle.setPrice((Double.parseDouble(vehicleForm.get("price").toString())));
biz.addVehicle(vehicle);
request.setAttribute("vehicle", vehicle);
return mapping.findForward("vehicleInfo");
}
}
提交不到这个Action中就出现异常

是不是你用了DispatchAction而没有配置parameter参数

我配置的DynaForm没有问题啊吗？
怎么总是出现上面那个异常？我以为是我的doule类型的错了，但是我改后还是出错？
