Rocketmq日志收集與logback集成Demo

官方文檔有簡潔的例子，這里就做一個簡單補充和實踐

1. 直接上logback-boot.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <!-- 文件輸出格式 -->
    <property name="PATTERN" value="%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n"/>
    <!-- 生產日志文件路徑 -->
    <property name="LOG_FILE_PATH" value="/home/tomapp/manager/logs"/>
    <!-- 開發環境 -->
    <springProfile name="dev">
        <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>${PATTERN}</pattern>
            </encoder>
        </appender>
        <logger name="com.tzxylao.manager" level="debug"/>
        <root level="info">
            <appender-ref ref="CONSOLE"/>
        </root>
    </springProfile>
    <!-- 生產環境 -->
    <springProfile name="prod">
        <!-- 每天產生一個文件 -->
        <appender name="PROD_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

            <!-- 文件路徑 -->
            <file>${LOG_FILE_PATH}/manager.log</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- 文件名稱 -->
                <fileNamePattern>${LOG_FILE_PATH}/manager.%d{yyyy-MM-dd}.log</fileNamePattern>
                <!-- 文件最大保存歷史數量 -->
                <MaxHistory>100</MaxHistory>
            </rollingPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>${PATTERN}</pattern>
            </layout>
        </appender>
        <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>${PATTERN}</pattern>
            </encoder>
        </appender>
        <appender name="mqAppender1" class="org.apache.rocketmq.logappender.logback.RocketmqLogbackAppender">
            <tag>TagA</tag>
            <topic>TopicTest</topic>
            <producerGroup>please_rename_unique_group_name</producerGroup>
            <nameServerAddress>47.101.45.25:9876</nameServerAddress>
            <layout>
                <pattern>%date %p %t - %m%n</pattern>
            </layout>
        </appender>

        <appender name="mqAsyncAppender1" class="ch.qos.logback.classic.AsyncAppender">
            <queueSize>1024</queueSize>
            <discardingThreshold>80</discardingThreshold>
            <maxFlushTime>2000</maxFlushTime>
            <neverBlock>true</neverBlock>
            <appender-ref ref="mqAppender1"/>
        </appender>

        <logger name="com.tzxylao.manager" level="debug"/>
        <root level="info">
            <appender-ref ref="PROD_FILE"/>
            <appender-ref ref="CONSOLE"/>
            <appender-ref ref="mqAppender1"/>
        </root>

    </springProfile>

</configuration>

• 這里有我本來的日志輸出，rocketmq的輸出主要是appender為mqAppender1、mqAsyncAppender1的這兩個，最后放入root節點就可以了
• 官方文檔路徑：https://rocketmq.apache.org/docs/logappender-example/
• 這里要起作用，必須把nameServerAddress，rocketmq服務地址配上
• 可能出錯的地方就是找不到對應的類了，這里給出我的引用pom

<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-client</artifactId>
    <version>4.3.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-logappender</artifactId>
    <version>4.3.0</version>
</dependency>

測試

1. 編寫個簡單的消費端服務，就拿官方的例子加上服務地址就行了

2. 好了，現在啟動消費端，再啟動配置了rocketmq日志的服務端

• 這是生產端打印
  

• 這是消費端打印
  

好了，日志收集后怎么用，自己發揮想象吧~~
