springboot集成日誌組件

如何管理微服務日誌

 通過logback拓展組件，將所有微服務日誌蒐集到es，按天建索引，通過kibana展示

1.引入maven依賴

<dependency>
	<groupId>com.internetitem</groupId>
	<artifactId>logback-elasticsearch-appender</artifactId>
	<version>1.6</version>
</dependency>

 2.引入logback.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <appender name="ELASTIC" class="com.internetitem.logback.elasticsearch.ElasticsearchAppender">
	<url>http://${log.hostname:-localhost}:${log.port:-8080}/_bulk</url>
        <index>logs-%date{yyyy-MM-dd}</index>
        <type>log</type>
        <loggerName>es-logger</loggerName> <!-- optional -->
        <errorLoggerName>es-error-logger</errorLoggerName> <!-- optional -->
        <connectTimeout>30000</connectTimeout> <!-- optional (in ms, default 30000) -->
        <errorsToStderr>false</errorsToStderr> <!-- optional (default false) -->
        <includeCallerData>false</includeCallerData> <!-- optional (default false) -->
        <logsToStderr>false</logsToStderr> <!-- optional (default false) -->
        <maxQueueSize>104857600</maxQueueSize> <!-- optional (default 104857600) -->
        <maxRetries>3</maxRetries> <!-- optional (default 3) -->
        <readTimeout>30000</readTimeout> <!-- optional (in ms, default 30000) -->
        <sleepTime>250</sleepTime> <!-- optional (in ms, default 250) -->
        <rawJsonMessage>false</rawJsonMessage> <!-- optional (default false) -->
        <includeMdc>false</includeMdc> <!-- optional (default false) -->
        <maxMessageSize>100</maxMessageSize> <!-- optional (default -1 -->
        <authentication class="com.internetitem.logback.elasticsearch.config.BasicAuthentication" /> <!-- optional -->

</configuration>

3 修改logback配置的兩種方式

第一種：修改logback配置文件中的localhost爲es的ip，8080爲es的http端口，defaultApp爲自己的微服務名稱

第二種：啓動jar包時指定配置，java -Dlog.hostname=es的ip -Dlog.port=es的http端口 -Dspring.application.name=服務名 -jar xxx.jar
