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
"net.logstash.logback:logstash-logback-encoder:4.11",
二、配置说明
1.日志的输出路径
<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
<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
<property name="CONSOLE_LOG_PATTERN"
value="[%d{yyyy-MM-dd HH:mm:ss.SSS} ${ip} ${appName} %highlight(%-5level) %yellow(%X{X-B3-TraceId}),%green(%X{X-B3-SpanId}),%blue(%X{X-B3-ParentSpanId}) %yellow(%thread) %green(%logger) %msg%n"/>
4.添加一个输出器，并滚动输出
<appender name="FILEERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">
5.指定输出的文件位置
<file>../${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
<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。
三、完整配置
