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。

<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启用log4j日志

pom.xml

  <!--排除默认的日志 -->   <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>   <!--启用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=truelog4j.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。
