Question

我有一个定义如下的枚举：

public enum IntervalType {
    HOUR(3600),
    DAY(3600*24),
    WEEK(3600*24*7),
    MONTH(3600*24*30);

    public Integer value;

    IntervalType() {}

    IntervalType(Integer value) {
        this.value = value;
    }

    @JsonValue
    public Integer toValue() {
        return this.value;
    }

    @JsonCreator
    public static IntervalType getEnumFromValue(String value) {
        for (IntervalType intervalType : IntervalType.values()) {
            if (intervalType.name().equals(value)) {
                return intervalType;
            }
        }
        throw new IllegalArgumentException();
    }

    @Override
    public String toString() {
        return this.name();
    }
}

我的响应类定义如下：

@Data
@AllArgsConstructor
@NoArgsConstructor
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(JsonInclude.Include.NON_NULL)
public class IntervalType {

    @JsonProperty("interval_type")
    @Enumerated(EnumType.STRING)
    private IntervalType intervalType;
}

我正在尝试从Spring Boot应用程序中使用Response实体返回此值，并且它给出枚举的值而不是其名称。

我该怎么做才能更改响应以使其具有名称而不是枚举的值？

Answer 1

您必须添加一个以值作为参数的构造函数：

通常，您这样称呼它：

Answer 2

如果您想要枚举的名称，请使用方法 name（），即：IntervalType.DAY.name()

 /**
 * Returns the name of this enum constant, exactly as declared in its
 * enum declaration.
 *
 * <b>Most programmers should use the {@link #toString} method in
 * preference to this one, as the toString method may return
 * a more user-friendly name.</b>  This method is designed primarily for
 * use in specialized situations where correctness depends on getting the
 * exact name, which will not vary from release to release.
 *
 * @return the name of this enum constant
 */
 public final String name() {
    return name;
 }

在API响应中返回Enum的值而不是Spring Boot中的名称
