java.lang.IllegalStateException Spring MVC

Question

嗨，我正在运行一个spring MVC应用程序，但是由于java.lang.IllegalStateException我

无法运行它。

IllegalStateException：既不是BindingResult也不是普通目标对象

for bean名称“unixmodel11”可作为请求属性使用

public class TroubleController{

@RequestMapping(value = "/index", method = RequestMethod.GET)

public ModelAndView welcomePage(Model model) {

    return new ModelAndView("index","unixModel11", new UnixModel());  


}
    @RequestMapping(value = "/loginUNIX", method = RequestMethod.POST)

   public String checkUnix(@ModelAttribute("unixModel11")UnixModel 

unixModel,ModelMap model）{

Model.AddAttribute（“username”,unixModel.getusername（））；

      model.addAttribute("host", unixModel.getHost());

      model.addAttribute("port", unixModel.getPort());

      return "result";

   }

}

无数的麻烦

<tr>

    <td><form:label path="host">Host Name</form:label></td>

    <td><form:input path="host" /></td>

</tr>

<tr>

    <td><form:label path="userName">User Name</form:label></td>

    <td><form:input path="userName" /></td>

</tr>

<tr>

    <td><form:label path="port">Port Number</form:label></td>

    <td><form:input path="port" /></td>

</tr>

<tr>

    <td colspan="2">

        <input type="submit" value="Submit"/>

    </td>

</tr>

包com.myriad.ihc.bean；

公共类UnixModel{

专用字符串主机；

专用字符串用户名；

专用整数端口；

return host;

}

public void setHost（字符串主机）{

this.host = host;

}

return userName;

this.userName = userName;

公共整数getPort（）{

return port;

}

public void setPort（整数端口）{

this.port = port;

}

}

我还在jsp页面中添加了commandName作为

Form：Form method=“Post”action=“loginunixs”commandname=“unixmodel11”
