SpringBoot启动报错：LoggerFactory is not a Logback LoggerContext but Logback is on the classpath

这个问题是slf4j包冲突所产生的问题，本博调试过程借鉴了下面链接所述博客，但情况与其不尽相同，博客将通过两种方式进行包的排除。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/zhanggong004/.m2/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/zhanggong004/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/C:/Users/zhanggong004/.m2/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory

当前使用的是org里的包，正常的日志打印需要的是logback的包

   ch.qos.logback
   >logback-classic
   1.2.3

   org.springframework.boot
   >spring-boot-starter-web



    com.101tec
    >zkclient
    0.10
    
        
            >slf4j-log4j12
            org.slf4j
        
    


  分别改为


     org.springframework.boot
     >spring-boot-starter-web
     
          
               org.slf4j
               >slf4j-log4j12
          
     



    com.101tec
    >zkclient
    0.10
    
        
            >slf4j-log4j12
