SpringBoot專案中怎麼保存控制台日誌

SpringBoot 控制台日誌的保存配置

情境：SpringBoot專案中需要把控制台日誌保存下來。

實作方法：

1.在設定檔application-prod.yml

設定如下：

logging:
  config: classpath:logback-spring-prod.xml

2.logback-spring-prod.xml

這個檔案是記錄控制台列印日誌保存的路徑配置如下：

<?xml version="1.0" encoding="UTF-8"?>
 
<!-- 分级别异步文件日志输出配置 -->
<configuration>
    <!-- 日志级别 -->
    <property name="logLevel" value="INFO"></property>
    <!-- 日志地址 -->

注意：

<property name="logPath" value="/usr/server/shop/logs/"></property>

中日誌存放的路徑在/usr/server/shop/logs /下存放。

SpringBoot專案怎麼保存服務的執行階段日誌

這個問題相對很簡單，只需要完成兩個步驟

設定log4j輸出日誌的檔案

在pom中需要引用lombok依賴,版本跟隨你的springboot夫版本即可

<dependency>
 <groupId>org.projectlombok</groupId>
 <artifactId>lombok</artifactId>
 <optional>true</optional>
</dependency>

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds"
	debug="false">
	<contextName>StudentContext</contextName>
	<property name="log.path" value="./logs" />
	<!--输出到控制台 -->
	<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
		<encoder>
			<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] %logger{76}.%M\(%line\) - %msg%n</pattern>

		</encoder>
	</appender>
	<!-- 全部日志 -->

		</encoder>
	</appender>
	<!-- 输出到warn -->
	<appender name="warn" class="ch.qos.logback.core.rolling.RollingFileAppender">

		<filter class="ch.qos.logback.classic.filter.LevelFilter"><!-- 只打印WARN日志 -->
			<level>WARN</level>

		</filter>
	</appender>

		<filter class="ch.qos.logback.classic.filter.LevelFilter"><!-- 只打印ERROR日志 -->

	</appender>
	<root level="info">
		<appender-ref ref="console" />
		<appender-ref ref="all" />
		<appender-ref ref="warn" />
		<appender-ref ref="error" />
	</root>
</configuration>

log4j輸出日誌的文件，將其放在resources下即可，注意fileNamePattern這個標籤中的東西換成標識你微服務作用的，像我寫的學生管理系統，所以用的是student

在application指定此設定檔的位置

logging:
  level:
    com.netflix.discovery.shared.resolver.aws.ConfigClusterResolver: WARN
  config: classpath:logback-common.xml
