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。

一、日志信息及错误 1、完整日志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

2、可以通过日志信息发现,两个jar包中的方法产生了冲突。
C:/Users/zhanggong004/.m2/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
C:/Users/zhanggong004/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class
当前使用的是org里的包,正常的日志打印需要的是logback的包
二、编辑pom.xml文件进行包的调整 1、根据一中的报错情况,我们在项目对应的pom.xml中增加了包,包的版本以实际情况设置>
>ch.qos.logback >
>logback-classic>
>1.2.3 >
>
2、同时,在原有的包后注明不再使用slf4j-log4j12方法。
>
>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>
>
