一种枚举的定义方式java

public enum LogLevel {
    HIGH("高危"),MEDIUM("中危"),LOW("低危"),INFO("信息");
    private String desc;

    LogLevel(String desc) {
        this.desc = desc;
    }

    public static Map<String, String> map() {
        Map<String, String> map = new HashMap<>();
        LogLevel[] values = LogLevel.values();
        for (LogLevel logLevel : values) {
            map.put(logLevel.name(), logLevel.desc);
        }
        return map;
    }

    public static String getDesc(String name) {
        if (StringUtils.isEmpty(name)) {
            return null;
        }
        Map<String, String> map = map();
        if(!map.containsKey(name)){
            return null;
        }
        LogLevel logLevel = LogLevel.valueOf(name);
        if (logLevel == null) {
            return null;
        }
        return logLevel.desc;


    }
}
