Springboot 使用logback直接将日志写入Elasticsearch
正常情况下,一般组合为elk 即日志会通过logstash写入es,但本文主要为轻量级项目直接利用appender写入es
首先需要引入包
<dependency>
<groupId>com.internetitem</groupId>
<artifactId>logback-elasticsearch-appender</artifactId>
<version>1.6</version>
</dependency>
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
<version>4.11</version>
</dependency>
添加logback-spring.xml到resource目录的根目录下
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<property name="LOGS" value="./logs"/>
<appender name="Console"
class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>
%black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%C{1.}): %msg%n%throwable
</Pattern>
</layout>
</appender>
<appender name="RollingFile"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOGS}/spring-boot-logger.log</file>
<encoder
class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
</encoder>
<rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily and when the file reaches 10 MegaBytes -->
<fileNamePattern>${LOGS}/archived/spring-boot-logger-%d{yyyy-MM-dd}.%i.log
</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<appender name="ELASTIC" class="com.internetitem.logback.elasticsearch.ElasticsearchAppender">

<!-- LOG everything at INFO level -->
<root level="info">
<appender-ref ref="RollingFile"/>
<appender-ref ref="Console"/>
<!--所有的日志都会通过ELASTIC为名的appender计入es-->
<appender-ref ref="ELASTIC"/>
</root>
<!-- LOG "com.baeldung*" at TRACE level -->
<logger name="com.baeldung" level="trace" additivity="false">
<appender-ref ref="RollingFile"/>
<appender-ref ref="ELASTIC"/>
</logger>
<logger name="es-logger" level="INFO" additivity="false">
<appender-ref ref="ELASTIC"/>
</logger>
</configuration>
在application.yml中设定日志level
logging:
level:
root: info
另外我们也可以在root部分不适用es记录日志而在需要的代码中用如下方式记录日志
package com.linkanyway.portal.controllers;
import com.linkanyway.sdk.exception.ApiResult;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author linkanyway
* @version 1.0
* @name EsLoggerController
* @description TODO
* @date 2020/12/13 13:14
*/
@RestController
@RequestMapping("log")
public class EsLoggerController {
private Logger logger = LoggerFactory.getLogger("es-logger");
@GetMapping("log")
public ApiResult<String> log()
{
logger.warn ("eslogger");
return ApiResult.success ("done!");
}
}
