Java 绑定映射<；字符串，HashMap<；字符串，字符串>&燃气轮机；HTML中文本框中的实例

我在play框架中工作，前端使用groovy脚本。我想将文本框中的值映射到相应模型对象中的

map

实例。为此，我使用了以下代码。但它们不起作用

下面给出了Html代码

    #{form @ControllerApp.review(), method:"POST"}
        <input class="new-party-address" type="hidden" value="Customer name: Pramil Address Line 1: NA " name="p.parties[added_1].strdaddress">
        <input class="new-party-address" type="hidden" value="Pramil" name="p.parties[added_1].address">
   <input type="Submit"/>
    #{/form}

public class PartyInput {
  public Map<String, HashMap<String, String>> parties = new HashMap<String, HashMap<String, String>>();
}

    public class ControllerApp extends Controller {
    public static void review(PartyInput p) {
    System.out.print(p); //null
    }
}

POST    /Controller/review     ControllerApp.review

public Map<String, HashMap<String, String>> parties = new HashMap<String, HashMap<String, String>>();

路由文件如下所示

    #{form @ControllerApp.review(), method:"POST"}
        <input class="new-party-address" type="hidden" value="Customer name: Pramil Address Line 1: NA " name="p.parties[added_1].strdaddress">
        <input class="new-party-address" type="hidden" value="Pramil" name="p.parties[added_1].address">
   <input type="Submit"/>
    #{/form}

public class PartyInput {
  public Map<String, HashMap<String, String>> parties = new HashMap<String, HashMap<String, String>>();
}

    public class ControllerApp extends Controller {
    public static void review(PartyInput p) {
    System.out.print(p); //null
    }
}

POST    /Controller/review     ControllerApp.review

public Map<String, HashMap<String, String>> parties = new HashMap<String, HashMap<String, String>>();

下面给出了Java代码

    #{form @ControllerApp.review(), method:"POST"}
        <input class="new-party-address" type="hidden" value="Customer name: Pramil Address Line 1: NA " name="p.parties[added_1].strdaddress">
        <input class="new-party-address" type="hidden" value="Pramil" name="p.parties[added_1].address">
   <input type="Submit"/>
    #{/form}

public class PartyInput {
  public Map<String, HashMap<String, String>> parties = new HashMap<String, HashMap<String, String>>();
}

    public class ControllerApp extends Controller {
    public static void review(PartyInput p) {
    System.out.print(p); //null
    }
}

POST    /Controller/review     ControllerApp.review

public Map<String, HashMap<String, String>> parties = new HashMap<String, HashMap<String, String>>();

publicmap parties=newhashmap（）；

但在java对象中，我将parties设置为null。我希望hashmpap结构为

{added_1={address=“Customer name:Pramil address Line 1:NA”，strddress=“Pramil”}

。为此，我必须做的是

请附上错误跟踪。没有错误。绑定不起作用请将html扩展到至少窗体的范围，并使用java代码
