后台form

package com.myunion.front.struts.form;

import org.apache.struts.action.ActionForm;


public class RegistFormComfig  extends ActionForm {
    
    private String usernumber ;
    private String usercard;

    public String getUsernumber() {
        return usernumber;
    }

    public void setUsernumber(String usernumber) {
        this.usernumber = usernumber;
    }

    public String getUsercard() {
        return usercard;
    }

    public void setUsercard(String usercard) {
        System.out.println("usercard:"+usercard);
        this.usercard = usercard;
    }

    public String getUser_Account() {
        return User_Account;
    }

    public void setUser_Account(String user_Account) {
        System.out.println("user_Account:"+user_Account);
        User_Account = user_Account;

        User_Password = user_Password;
    }


    public String getUser_Age() {
        return User_Age;
    }

    public void setUser_Age(String user_Age) {
        User_Age = user_Age;
    }

    public String getUser_Shen() {
        return User_Shen;
    }

    public void setUser_Shen(String user_Shen) {
        User_Shen = user_Shen;
    }

    public String getUser_Town() {

    }

    public void setUser_Email(String user_Email) {
        User_Email = user_Email;
    }

    public String getUser_Question() {
        return User_Question;
    }

    public void setUser_Question(String user_Question) {
        User_Question = user_Question;
    }

    public String getUser_Answer() {
        return User_Answer;
    }

    public void setUser_Answer(String user_Answer) {
        User_Answer = user_Answer;
    }

    public String getAuthcode() {
        return authcode;
    }

    public void setAuthcode(String authcode) {
        this.authcode = authcode;
    }

    public String getUser_RePassword() {
        return User_RePassword;
    }

    public void setUser_RePassword(String user_RePassword) {
        User_RePassword = user_RePassword;
    }

    public String getCheckbox() {
        return checkbox;

    }

    public String getIdentifier() {
        return identifier;
    }

    public void setIdentifier(String identifier) {
        this.identifier = identifier;
    }

    @Override
    public String toString() {
        return  "usernumber:"+ usernumber + " usercard:"+usercard+" User_Account:"+User_Account+" User_Password:"+ User_Password
        +" User_Age:"+User_Age+" User_Shen:"+User_Shen +" User_Town:"+ User_Town+" User_City:"+User_City
        +" User_Email:"+User_Email+" User_Question:"+User_Question+" User_Answer:"+User_Answer+" authcode:"+authcode+" checkbox:"+checkbox;
    }

    
}

 后台显示

usernumber:aaaaaaa usercard:1111111111111 User_Account:null User_Password:null User_Age:null User_Shen:null User_Town:null User_City:null User_Email:null User_Question:null User_Answer:null authcode:ADSF checkbox:checkbox

为什么只能获得4个值

<action
      path="/RegistComfig"
      scope="request"
      name="RegistFormComfig"
      type="com.myunion.front.struts.action.RegisterComfig" >
      </action>

 <form-bean name="RegistFormComfig" type="com.myunion.front.struts.form.RegistFormComfig" />

兄弟，我想起来了

get请求时把参数放在HTTP协议头上，大小好像是256；

而post请求是放在HTTP协议体上，几乎可以无限大，只要HTTP支持即可。

希望对你有帮助！
