springBoot启动报错log4j冲突的解决方案

springBoot启动报错log4j冲突

先上一段报错内容

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/log4j-slf4j-impl-2.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/logback-classic-1.1.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
......
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:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/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

springBoot 本地报错，查了一番，是logback搞得鬼，打开pom依赖树，搜索logback，发现在spring-boot-starter-web下有间接依赖上logback-classisc，搜索大神们的解答，就是在有这个依赖的dependency中除去他就行了。

        org.springframework.boot
        spring-boot-starter-web
        
                
                    ch.qos.logback
                   logback-classic
                
           

SpringBoot启用log4j日志

pom.xml

   
  
      org.springframework.boot
      spring-boot-starter
      
          
              org.springframework.boot
              spring-boot-starter-logging
          
      
  
     
  
    org.springframework.boot
    spring-boot-starter-log4j
    1.2.8.RELEASE
  

log4j.properties

log4j.rootLogger=debug, ServerDailyRollingFile, stdout 
log4j.appender.ServerDailyRollingFile=org.apache.log4j.DailyRollingFileAppender 
log4j.appender.ServerDailyRollingFile.DatePattern='.'yyyy-MM-dd 
log4j.appender.ServerDailyRollingFile.File=C\://logs/notify-subscription.log 
log4j.appender.ServerDailyRollingFile.layout=org.apache.log4j.PatternLayout 
log4j.appender.ServerDailyRollingFile.layout.ConversionPattern=%d - %m%n 
log4j.appender.ServerDailyRollingFile.Append=true

log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} %p [%c] %m%n

log4j.properties放在resources目录下，这个log4j是随便配的。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
