Question

所以我有这段代码：

public class AccountService {

private Map<String, Account> accounts = DatabaseClass.getAccounts();


public AccountService(){
    Account acc = new Account();
    acc.setNickname("1");
    acc.setPassword("2");
    accounts.put("1", acc);
}
public List<Account> getAllAccounts(){
    return new ArrayList<Account>(accounts.values());
}

public Account addAccount(String nickname, Account acc){
    accounts.put(nickname, acc);
    return acc;
}

public Account validateAccount(String nickname, String password){
    Account acc = new Account(nickname,password);
    if (accounts.containsValue(acc)){
        acc.setNickname("true");
        acc.setPassword("true");
    }
    return acc;
}


public class AccountResource {

AccountService accountservice = new AccountService();


@GET
public List<Account> getAllAccounts(){
    return accountservice.getAllAccounts();

}

@POST
@Path("/{nickname}")
public Account addAccount(@PathParam("nickname") String nickname,Account acc){
    return accountservice.addAccount(nickname,acc);

}


@GET
@Path("/{nickname}/{password}")
public Account validateAccount(@PathParam("nickname")String nickname, @PathParam("password") String password){
return accountservice.validateAccount(nickname , password);
}



public class DatabaseClass {

private static Map<String, Playlist> playlists = new HashMap<String, Playlist>();
private static Map<String, Account> accounts = new HashMap<String, Account>();


public static Map<String,Account> getAccounts (){
    return accounts;    
}

}

我试图查看地图（帐户）是否包含与acc具有相同参数的对象。 constainsValue的部分对我不起作用。有什么建议？我已添加新对象以使用值1和2进行映射。

我已经替换了这段代码：

public Account validateAccount(String nickname, String password){
Account acc = new Account(nickname,password);
if (accounts.containsValue(acc)){
    acc.setNickname("true");
    acc.setPassword("true");
}
return acc;

}

有了这个：

public Account validateAccount(String nickname, String password){
    Account acc = new Account(nickname,password);
    Account a= new Account();
    if (accounts.containsKey(nickname)){
        a = accounts.get(nickname);
        if(acc.getNickname().equals(a.getNickname()) && acc.getPassword().equals(a.getPassword())){
            acc.setNickname("true");
            acc.setPassword("true");
        }
    }
    return acc;
}

这解决了我的问题。感谢

我可以在地图中搜索对象吗？
