我收到上面的错误.
我要做的是编写一个接收未知数量名称的应用程序,然后在新页面上打印出来.这应该是一个保龄球得分应用程序,但现在我只想得到一个名单.这个想法是让每个名字进入一个玩家对象,然后存储在玩家arraylist中.如果有人可以提供帮助,我将不胜感激.
这是我的控制器代码：
package multiplayergame;
import java.util.ArrayList;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;
@Controller
@SessionAttributes
public class MultiplayerController {
int score;
int roll;
Game game = new Game();
GameProperties gameProps = new GameProperties();
int playerNo = 0;
ArrayList
这包含每个玩家的详细信息：
package multiplayergame;
public class PlayerGame {
private int score;
private int pins;
private String name;
private int roll;
private int nOfPlayers;
private int playerNo;
Game game = new Game();
public Game getGame() {
return game;
}
public void setGame(Game game) {
this.game = game;
}
public int getScore() {
return score;
}
public void setScore(int score) {
this.score = score;
}
public int getPins() {
return pins;
}
public void setPins(int pins) {
this.pins = pins;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getRoll() {
return roll;
}
public void setRoll(int roll) {
this.roll = roll;
}
public int getnOfPlayers() {
return nOfPlayers;
}
public void setnOfPlayers(int nOfPlayers) {
this.nOfPlayers = nOfPlayers;
}
public int getPlayerNo() {
return playerNo;
}
public void setPlayerNo(int playerNo) {
this.playerNo = playerNo;
}
}
这是所有游戏属性的代码,例如得分等.
package multiplayergame;
import java.util.ArrayList;
public class GameProperties {
private int score;
private int pins;
private String name;
private int roll;
private int nOfPlayers;
PlayerGame player;
private ArrayList
以下是我的JSP文件,输出优先：
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
这是主页：
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
更改此< c：forEach var =“player”items =“players”> to< c：forEach var =“player”items =“${players}”>
作为你引用的“玩家”字符串.它试图在字符串中找到属性名称.
