logback 日志处理

今天项目上接到一个需求 要求改日志信息

BL##告警级别#告警编码#告警对象#告警产生时间#主机名|IP#业务系统名称#子系统名称#模块名称#实例名称#告警类别#告警内容#业务相关方#详细信息##LB

开头结尾 加个配置拼上去就行了

设置ip及地址

package com.ztesoft.hjreport.hjreportconfig.utils;

import ch.qos.logback.classic.pattern.ClassicConverter;
import ch.qos.logback.classic.spi.ILoggingEvent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.net.InetAddress;
import java.net.UnknownHostException;

public class LogIpConfig extends ClassicConverter {
    private static final Logger LOGGER = LoggerFactory.getLogger(LogIpConfig .class);
    @Override
    public String convert(ILoggingEvent event) {
        try {
            return InetAddress.getLocalHost().getHostAddress();
        } catch (UnknownHostException e) {
            LOGGER.error("获取日志Ip异常", e);
        }
        return null;
    }
}

%ip

主机名称

package com.ztesoft.hjreport.hjreportconfig.configuration;

import ch.qos.logback.core.PropertyDefinerBase;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class GetLogBackHostNameConfiguration extends PropertyDefinerBase {

    @Override
    public String getPropertyValue() {

        try {
            return InetAddress.getLocalHost().getHostName();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        return null;
    }

}

${HOST_NAME}

告警级别

Output just one letter for the level

Instead of printing TRACE, DEBUG, WARN, INFO or ERROR for the level, you may want to print just T, D, W, I and E. You could write a custom converter [^ 自定义转换器] for this purpose, or simply make use of format modifiers (just discussed) to shorten the level value to a single character. The appropriate conversion specifier would be "%.-1level".

http://logback.qos.ch/manual/layouts.html#customConversionSpecifier

package com.ztesoft.hjreport.hjreportconfig.utils;

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.pattern.ClassicConverter;
import ch.qos.logback.classic.spi.ILoggingEvent;

public class MySampleConverter extends ClassicConverter {

  long start = System.nanoTime();

  @Override
  public String convert(ILoggingEvent event) {
    Level level = event.getLevel();
    long nowInNanos = System.nanoTime();
    if(level.levelStr.equals("WARN")){
       return "WARNING";
    }
    if(level.levelStr.equals("ERROR")){
      return "SERIOUS";
    }
    return level.levelStr;
  }

}

主要的日志级别

/**
 * The OFF is used to turn off logging.
 */
public static final Level OFF = new Level(OFF_INT, "OFF");

/**
 * The ERROR level designates error events which may or not
 * be fatal to the application.
 */
public static final Level ERROR = new Level(ERROR_INT, "ERROR");

/**
 * The WARN level designates potentially harmful situations.
 */
public static final Level WARN = new Level(WARN_INT, "WARN");

/**
 * The INFO level designates informational messages
 * highlighting overall progress of the application.
 */
public static final Level INFO = new Level(INFO_INT, "INFO");

/**
 * The DEBUG level designates informational events of lower
 * importance.
 */
public static final Level DEBUG = new Level(DEBUG_INT, "DEBUG");

/**
 * The TRACE level designates informational events of very low
 * importance.
 */
public static final Level TRACE = new Level(TRACE_INT, "TRACE");

/**
 * The ALL is used to turn on all logging.
 */
public static final Level ALL = new Level(ALL_INT, "ALL");

修改后的结果 (logback.xml)
