枚舉的內容可以使用map的方式

package com.chinamobile.framework.common.enums;import org.springframework.util.CollectionUtils; import org.springframework.util.StringUtils;import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map;@SuppressWarnings("unused") public interface BaseEnum {String getKey();String getValue();static <E> boolean isKeyExists(Class<E> enumClass, String key) {if (StringUtils.isEmpty(key)) {return false;}List<String> keys = getKeyList(enumClass);if (CollectionUtils.isEmpty(keys)) {return false;}return keys.contains(key);}static <E> boolean isValueExists(Class<E> enumClass, String value) {if (StringUtils.isEmpty(value)) {return false;}List<String> values = getValueList(enumClass);if (CollectionUtils.isEmpty(values)) {return false;}return values.contains(value);}static <E> List<String> getKeyList(Class<E> enumClass) {List<String> list = new ArrayList<>();if (!BaseEnum.class.isAssignableFrom(enumClass)) {return list;}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;list.add(ce.getKey());}return list;}static <E> List<String> getValueList(Class<E> enumClass) {List<String> list = new ArrayList<>();if (!BaseEnum.class.isAssignableFrom(enumClass)) {return list;}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;list.add(ce.getValue());}return list;}static <E> List<Map<String, String>> getMapList(Class<E> enumClass) {List<Map<String, String>> mapList = new ArrayList<>();if (!BaseEnum.class.isAssignableFrom(enumClass)) {return mapList;}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;Map<String, String> map = new HashMap<>();map.put("key", ce.getKey());map.put("value", ce.getValue());mapList.add(map);}return mapList;}static List<Map<String, String>> getMapList(BaseEnum... enumData) {List<Map<String, String>> mapList = new ArrayList<>();for (BaseEnum ed : enumData) {Map<String, String> map = new HashMap<>();map.put("key", ed.getKey());map.put("value", ed.getValue());mapList.add(map);}return mapList;}static Map<String, String> getMap(BaseEnum enumData) {Map<String, String> enumMap = new HashMap<>();enumMap.put("key", enumData.getKey());enumMap.put("value", enumData.getValue());return enumMap;}static <E> String key2Value(Class<E> enumClass, String key) {if (!BaseEnum.class.isAssignableFrom(enumClass)) {return "";}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;if (ce.getKey().equals(key)) {return ce.getValue();}}return "";}static <E> List<String> key2Value(Class<E> enumClass, List<String> keys) {if (CollectionUtils.isEmpty(keys)) {return new ArrayList<>();}List<String> values = new ArrayList<>();for (String key : keys) {values.add(key2Value(enumClass, key));}return values;}static <E> E key2Enum(Class<E> enumClass, String key) {if (!BaseEnum.class.isAssignableFrom(enumClass)) {return null;}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;if (ce.getKey().equals(key)) {return e;}}return null;}static <E> List<E> key2Enum(Class<E> enumClass, List<String> keys) {if (CollectionUtils.isEmpty(keys)) {return new ArrayList<>();}List<E> enums = new ArrayList<>();for (String key : keys) {enums.add(key2Enum(enumClass, key));}return enums;}static <E> String value2Key(Class<E> enumClass, String value) {if (!BaseEnum.class.isAssignableFrom(enumClass)) {return "";}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;if (ce.getValue().equalsIgnoreCase(value)) {return ce.getKey();}}return "";}static <E> List<String> value2Key(Class<E> enumClass, List<String> values) {if (CollectionUtils.isEmpty(values)) {return new ArrayList<>();}List<String> keys = new ArrayList<>();for (String value : values) {keys.add(value2Key(enumClass, value));}return keys;}static <E> E value2Enum(Class<E> enumClass, String value) {if (!BaseEnum.class.isAssignableFrom(enumClass)) {return null;}for (E e : enumClass.getEnumConstants()) {BaseEnum ce = (BaseEnum) e;if (ce.getValue().equals(value)) {return e;}}return null;}static <E> List<E> value2Enum(Class<E> enumClass, List<String> values) {if (CollectionUtils.isEmpty(values)) {return new ArrayList<>();}List<E> enums = new ArrayList<>();for (String value : values) {enums.add(value2Enum(enumClass, value));}return enums;}}

下面是繼承的示例

public enum OracleErrorTypeEnum implements BaseEnum {DemandTask("DemandTask","需求調查任務"),DemandReport("DemandReport","需求調查填報"),DemandSummary("DemandSummary","需求調查匯總"),NEEDS_SURVEY( "NEEDS_SURVEY","需求調查業務");private String key;private String value;/*構造函數*/private OracleErrorTypeEnum(String key, String value) {this.key = key;this.value = value;}public String getKey() {return key;}public void setKey(String key) {this.key = key;}public String getValue() {return value;}public void setValue(String value) {this.value = value;}}
