可以考虑使用 JavaFX 自带的 javafx.util.Pair 。但是如果你是项目是SpringBoot的话，可能会遇到运行正常但是打包为jar包的时候找不到包的错误。这个时候可以考虑复制Pair的内容到自己的工具类包下，而非去引入JavaFX 。

Pair.java

import java.io.Serializable;

/**
 * <p>A convenience class to represent name-value pairs.</p>
 * @since JavaFX 2.0 (javafx.util.Pair;)
 */
public class Pair <K,V> implements Serializable {

    /**
     * Key of this <code>Pair</code>.
     */
    private K key;

    /**
     * Gets the key for this pair.
     * @return key for this pair
     */
    public K getKey() { return key; }

    /**
     * Value of this this <code>Pair</code>.
     */
    private V value;

    /**
     * Gets the value for this pair.
     * @return value for this pair
     */
    public V getValue() { return value; }

    /**
     * Creates a new pair
     * @param key The key for this pair
     * @param value The value to use for this pair
     */
    public Pair( K key,  V value) {
        this.key = key;
        this.value = value;
    }

    /**
     * <p><code>String</code> representation of this
     * <code>Pair</code>.</p>
     *
     * <p>The default name/value delimiter '=' is always used.</p>
     *
     *  @return <code>String</code> representation of this <code>Pair</code>
     */
    @Override
    public String toString() {
        return key + "=" + value;
    }

    /**
     * <p>Generate a hash code for this <code>Pair</code>.</p>
     *
     * <p>The hash code is calculated using both the name and
     * the value of the <code>Pair</code>.</p>
     *
     * @return hash code for this <code>Pair</code>
     */
    @Override
    public int hashCode() {
        // name's hashCode is multiplied by an arbitrary prime number (13)
        // in order to make sure there is a difference in the hashCode between
        // these two parameters:
        //  name: a  value: aa
        //  name: aa value: a
        return key.hashCode() * 13 + (value == null ? 0 : value.hashCode());
    }

     */
    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o instanceof Pair) {
            Pair pair = (Pair) o;
            if (key != null ? !key.equals(pair.key) : pair.key != null) return false;
            if (value != null ? !value.equals(pair.value) : pair.value != null) return false;
            return true;
        }
        return false;
    }
}

使用例子

        List<Pair<Integer, String>> enumsList = new ArrayList<Pair<Integer, String>>();
        for (ChannelTypeEnums channelTypeEnums : ChannelTypeEnums.values()) {
            enumsList.add(new  Pair<Integer, String>(channelTypeEnums.getCode(),channelTypeEnums.getMsg()));
        }
