小编给大家分享一下如何使用logback实现按需求打印日志到自定义的文件里，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

1、工具类 LoggerUtils

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class LoggerUtils {
    public static <T> Logger Logger(Class<T> clazz) {
        return LoggerFactory.getLogger(clazz);
    }
    /**
     * 打印到指定的文件下
     *
     * @param desc 日志文件名称
     * @return
     */
    public static Logger Logger(LogFileName desc) {
        return LoggerFactory.getLogger(desc.getLogFileName());
    }
}

2、枚举类 LogFileName

import org.apache.commons.lang3.StringUtils;
public enum LogFileName {
    //配置到logback.xml中的logger name="getNextHh"
    GET_NEXT_HH("getNextHh"),
    GET_AGAIN_HH("getAgainHh"),
    GET_AI_ACTION("getAiAction"),
    TRAIN_ERROR("trainError"),
    USER_ERROR("userError"),
    PAY_ERROR("payError"),
    REVIEW_ERROR("reviewError"),
    WX_ERROR("wxError"),
    SYSTEM_ERROR("systemError"),
    PAY_DEBUG("payDebug");
    private String logFileName;
    LogFileName(String fileName) {
        this.logFileName = fileName;
    }
    public String getLogFileName() {
        return logFileName;
    }
    public void setLogFileName(String logFileName) {
        this.logFileName = logFileName;
    }
    public static LogFileName getAwardTypeEnum(String value) {
        LogFileName[] arr = values();
        for (LogFileName item : arr) {
            if (null != item && StringUtils.isNotBlank(item.logFileName)) {
                return item;
            }
        }
        return null;
    }
}

3、logger.xml, 按需配置即可

<?xml version="1.0" encoding="UTF-8"?>
