springboot 使用logback啟動報警報錯的解決

springboot logback啟動報警報錯

報錯信息如下：

16:06:07,484 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]
16:06:07,484 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]
16:06:07,485 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback.xml] at [file:/C:/Users/Administrator/Desktop/***/***/target/classes/logback.xml]
16:06:07,638 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set
16:06:07,646 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender]
16:06:07,653 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [consoleAppender]

先說解決方法：

把日志文件名稱改為-spring結尾就不報警瞭!!! logback-spring.xml

tips(springboot日志使用logback):

Spring Boot官方推薦優先使用帶有-spring的文件名作為你的日志配置（如使用logback-spring.xml，而不是logback.xml），如果想自定義文件名，可以通過logging.config屬性指定自定義的名字：

logging.config=classpath:my-logging-config.xml

官方start包中已經默認集成瞭slf4j和logback不用導入任何日志依賴

推薦使用logback，性能優於log4j

設置logback彩色日志

<property name="log.consolePattern" value="%highlight(%date{yyyy-MM-dd HH:mm:ss.SSS}) %boldYellow([%thread]) %highlight([%-5level])  %boldCyan([%replace(%caller{1}){'\t|Caller.{1}0|\r\n', ''}]) %msg%n"/>

<!-- 控制臺設置,主要是上方pattern修改就可以，其他地方可以用不同pattern -->
<appender name="CONSOLE_APPENDER" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>${log.consolePattern}</pattern>  <!-- 控制臺日志輸出格式 -->
        <charset>utf8</charset>
    </encoder>
</appender>

springboot多環境開發日志

<!-- 測試環境+開發環境. 多個使用逗號隔開 -->
<springProfile name="test,dev">
 <logger name="工程包路徑" level="info" />
</springProfile>
<!-- 生產環境. -->
<springProfile name="prod">
 <logger name="工程包路徑" level="ERROR" />
</springProfile>

springboot使用logback會遇到的坑

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.apache.logging.slf4j.Log4jLoggerFactory loaded from file:/C:/Users/fyk/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.7/log4j-slf4j-impl-2.7.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.apache.logging.slf4j.Log4jLoggerFactory

在spring boot中導入logback jar包會與spring-boot-starter-web沖突，應該是springboot中已經包含瞭這個包，

   <dependency>
   <groupId>ch.qos.logback</groupId>
   <artifactId>logback-classic</artifactId>
   <version>1.2.3</version>
  </dependency>

去掉這個導入就好瞭！

以上為個人經驗，希望能給大傢一個參考，也希望大傢多多支持WalkonNet。
