java 动态 枚举_java 动态生成枚举值

在某些场景下我们需要动态生成一些枚举值，主要是通过反射生成，但是这种生成枚举值是不能switch的

1.枚举值类

public enum CodeInfoEnum {

LOCK(1L, 1L, "LOCK_TYPE", "LOCK"), UNLOCK(1L, 2L, "LOCK_TYPE", "LOCK");

public Long classId;

public Long infoId;

public String classCode;

public String infoCode;

CodeInfoEnum(Long classId, Long infoId, String classCode, String infoCode) {

this.classId = classId;

this.infoId = infoId;

this.classCode = classCode;

this.infoCode = infoCode;

}

public static CodeInfoEnum getByInfoId(Long infoId) {

return CodeInfoEnum.valueOf(infoId + "");

}

public static List getByClassId(Long classId) {

return Arrays.stream(CodeInfoEnum.values()).filter(item -> item.classId.equals(classId)).collect(Collectors.toList());
