使用logback实现按自己的需求打印日志到自定义的文件里

作者：烛火下的乌托邦丶 时间：2022-05-12 16:56:49　

  • 定义工具类-创建对应的日志对象

  • 定义枚举类-存储定义的日志文件名称

  • logback.xml里配置对应的日志名称和日志等级

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"?>

              xsi:noNamespaceSchemaLocation="http://www.padual.com/java/logback.xsd" debug="false"
