在项目中枚举的名称（name）和值(value)需要相互之间转化，翻译它的名称或者值

主要使用的类ConvertEnum

ConvertEnum类

package com.elvesfish.ms.common.denum; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; import lombok.extern.slf4j.Slf4j; /** * @author: elvesfish * @date: 2019/5/22 */ @Slf4j public class ConvertEnum<T extends Enum<T>> { public static <T extends Enum<T>> String nameToValue(String name, Class<T> clazz) { return nameToValueCommon(name, clazz, "getName", "getValue"); } public static <T extends Enum<T>> String nameToValue(String name, Class<T> clazz, String getName, String getValue) { return nameToValueCommon(name, clazz, getName, getValue); } public static <T extends Enum<T>> String valueToName(String value, Class<T> clazz) { return nameToValueCommon(value, clazz, "getValue", "getName"); } public static <T extends Enum<T>> String valueToName(String value, Class<T> clazz, String getValue, String getName) { return nameToValueCommon(value, clazz, getValue, getName); } public static <T extends Enum<T>> String[] namesToValues(String[] names, Class<T> clazz) { String[] result = new String[names.length]; return Arrays.stream(names).map(p -> nameToValue(p, clazz)).collect(Collectors.toList()).toArray(result); } public static <T extends Enum<T>> String[] namesToValues(String[] names, Class<T> clazz, String getName, String getValue) { String[] result = new String[names.length]; return Arrays.stream(names).map(p -> nameToValue(p, clazz, getName, getValue)).collect(Collectors.toList()).toArray(result); } public static <T extends Enum<T>> String[] valuesToNames(String[] values, Class<T> clazz) { String[] result = new String[values.length]; return Arrays.stream(values).map(p -> valueToName(p, clazz)).collect(Collectors.toList()).toArray(result); } public static <T extends Enum<T>> String[] valuesToNames(String[] values, Class<T> clazz, String getValue, String getName) { String[] result = new String[values.length]; return Arrays.stream(values).map(p -> valueToName(p, clazz, getValue, getName)).collect(Collectors.toList()).toArray(result); } public static <T extends Enum<T>> List<String> namesToValuesByList(List<String> names, Class<T> clazz) { return names.stream().map(p -> nameToValue(p, clazz)).collect(Collectors.toList()); } public static <T extends Enum<T>> List<String> namesToValuesByList(List<String> names, Class<T> clazz, String getName, String getValue) { return names.stream().map(p -> nameToValue(p, clazz, getName, getValue)).collect(Collectors.toList()); } public static <T extends Enum<T>> List<String> valuesToNamesByList(List<String> values, Class<T> clazz) { return values.stream().map(p -> valueToName(p, clazz)).collect(Collectors.toList()); } public static <T extends Enum<T>> List<String> valuesToNamesByList(List<String> values, Class<T> clazz, String getValue, String getName) { return values.stream().map(p -> valueToName(p, clazz, getValue, getName)).collect(Collectors.toList()); } public static <T extends Enum<T>> String nameToValueCommon(String name, Class<T> clazz, String getName, String getValue) { T t = getStringByTypeCode(clazz, getName, name); //获取定义的方法 String typeCodeVal = ""; if (t != null) { try { Method targetMethod = clazz.getDeclaredMethod(getValue); //获取传过来方法的 typeCodeVal = targetMethod.invoke(t).toString(); } catch (NoSuchMethodException e) { log.error("NoSuchMethodException", e); } catch (IllegalAccessException e) { log.error("IllegalAccessException", e); } catch (InvocationTargetException e) { log.error("InvocationTargetException", e); } } return typeCodeVal; } public static <T extends Enum<T>> T getStringByTypeCode(Class<T> clazz, String getTypeCodeMethodName, String typeCode) { T result = null; try { //Enum接口中没有values()方法，我们仍然可以通过Class对象取得所有的enum实例 T[] arr = clazz.getEnumConstants(); //获取定义的方法 Method targetMethod = clazz.getDeclaredMethod(getTypeCodeMethodName); String typeCodeVal = null; //遍历枚举定义 for (T entity : arr) { //获取传过来方法的 typeCodeVal = targetMethod.invoke(entity).toString(); //执行的方法的值等于参数传过来要判断的值 if (typeCodeVal.equals(typeCode)) { //返回这个枚举 result = entity; break; } } } catch (IllegalAccessException e) { log.error("IllegalAccessException", e); } catch (IllegalArgumentException e) { log.error("IllegalArgumentException", e); } catch (InvocationTargetException e) { log.error("InvocationTargetException", e); } catch (NoSuchMethodException e) { log.error("NoSuchMethodException", e); } catch (SecurityException e) { log.error("SecurityException", e); } return result; } }

项目中定义的枚举CurrentEnum

package com.elvesfish.ms.common.denum; public enum CurrentEnum { /** * 在用 */ USEING("在用", "1"), /** * 历史版本 */ HISTORY("历史版本", "2"); private String name; private String value; public String getName() { return name; } public String getValue() { return value; } CurrentEnum(String name, String value) { this.name = name; this.value = value; } }

周期枚举 

package com.elvesfish.ms.common.denum; public enum CycleEnum { /** * 年 */ YEAR("年", "1"), MONTH("月", "2"), DAY("日", "3"), SEASON("季", "4"), WEEKS("周", "5"), CUSTOM("自定义", "6"); private String name; private String value; public String getName() { return name; } public String getValue() { return value; } CycleEnum(String name, String value) { this.name = name; this.value = value; } }
