springBoot啟動報錯log4j沖突

先上一段報錯內容

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 本地報錯，查了一番，是logback搞得鬼，打開pom依賴樹，搜索logback，發現在spring-boot-starter-web下有間接依賴上logback-classisc，搜索大神們的解答，就是在有這個依賴的dependency中除去他就行了。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
                <exclusion>
                    <groupId>ch.qos.logback</groupId>
                   <artifactId>logback-classic</artifactId>
                </exclusion>
           </exclusions>
</dependency>

SpringBoot啟用log4j日志

pom.xml

  <!--排除默認的日志 --> 
  <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter</artifactId>
      <exclusions>
          <exclusion>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-logging</artifactId>
          </exclusion>
      </exclusions>
  </dependency>
   <!--啟用log4j日志 -->  
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j</artifactId>
    <version>1.2.8.RELEASE</version>
  </dependency>

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目錄下，這個log4j是隨便配的。
