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。

目录
一、日志信息及错误
二、编辑pom.xml文件进行包的调整
三、直接在IDEA依赖图中进行修改
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.Log4jLoggerFactoryat org.springframework.util.Assert.instanceCheckFailed(Assert.java:655)at org.springframework.util.Assert.isInstanceOf(Assert.java:555)at org.springframework.boot.logging.logback.LogbackLoggingSystem.getLoggerContext(LogbackLoggingSystem.java:286)at org.springframework.boot.logging.logback.LogbackLoggingSystem.beforeInitialize(LogbackLoggingSystem.java:102)at org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationStartingEvent(LoggingApplicationListener.java:220)at org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationEvent(LoggingApplicationListener.java:199)at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172)at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165)at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139)at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:127)at org.springframework.boot.context.event.EventPublishingRunListener.starting(EventPublishingRunListener.java:69)at org.springframework.boot.SpringApplicationRunListeners.starting(SpringApplicationRunListeners.java:48)at org.springframework.boot.SpringApplication.run(SpringApplication.java:302)at org.springframework.boot.SpringApplication.run(SpringApplication.java:1260)at org.springframework.boot.SpringApplication.run(SpringApplication.java:1248)at com.example.dubboconsumer.DubboConsumerApplication.main(DubboConsumerApplication.java:13)
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
<dependency><groupId>ch.qos.logback</groupId><artifactId>logback-classic</artifactId><version>1.2.3</version>
</dependency>
2、同时,在原有的包后注明不再使用slf4j-log4j12方法。
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency><dependency><groupId>com.101tec</groupId><artifactId>zkclient</artifactId><version>0.10</version><exclusions><exclusion><artifactId>slf4j-log4j12</artifactId><groupId>org.slf4j</groupId></exclusion></exclusions>
</dependency>分别改为<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions>
</dependency><dependency><groupId>com.101tec</groupId><artifactId>zkclient</artifactId><version>0.10</version><exclusions><exclusion><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions>
</dependency>
