完整的logback配置示例ELK整合包含生成json日志

一、依赖

由于配置中使用了json格式的日志输出，所以需要引入如下依赖

?

1

"net.logstash.logback:logstash-logback-encoder:4.11",

二、配置说明

1.日志的输出路径

?

1

< property name = "LOG_PATH" value = "phantom-log" />

2.读取spring容器中的属性，这里是获取项目名称和运行的服务器IP

?

1

2

< springProperty scope = "context" name = "appName" source = "spring.application.name" />

< springProperty scope = "context" name = "ip" source = "spring.cloud.client.ipAddress" />

3.设置日志的格式

?

1

2

< property name = "CONSOLE_LOG_PATTERN"

             value = "[%d{yyyy-MM-dd HH:mm:ss.SSS} ${ip} ${appName} %highlight(%-5level) %yellow(%X{X-B3-TraceId}),%green(%X{X-B3-SpanId}),%blue(%X{X-B3-ParentSpanId}) %yellow(%thread) %green(%logger) %msg%n" />

4.添加一个输出器，并滚动输出

?

1

< appender name = "FILEERROR" class = "ch.qos.logback.core.rolling.RollingFileAppender" >

5.指定输出的文件位置

?

1

< file >${LOG_PATH}/${appName}/${appName}-error.log</ file >

6.指定滚动输出的策略，按天数进行切分，或者文件大小超过2M进行切分

?

1

2

4

5

6

< rollingPolicy class = "ch.qos.logback.core.rolling.TimeBasedRollingPolicy" >

       < fileNamePattern >${LOG_PATH}/${appName}/${appName}-error-%d{yyyy-MM-dd}.%i.log</ fileNamePattern >

       < timeBasedFileNamingAndTriggeringPolicy class = "ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP" >

         < maxFileSize >2MB</ maxFileSize >

       </ timeBasedFileNamingAndTriggeringPolicy >

     </ rollingPolicy >

7.下面的文件中一共有四个appender, FILEERROR, FILEEWARN, FILEINFO, logstash。

其中FILEERROR, FILEEWARN, FILEINFO三个是相类似的，只是打印不同级别的日志信息。
logstash是用来生成json格式的日志文件，方便与ELK日志系统进行集成。
