4.1 springboot中log4j沖突規避！

參考 https://blog.csdn.net/g631521612/article/details/82381435?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-1.control&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-1.control

 

SLF4J: Class path contains multiple SLF4J bindings.

 

SLF4J: Found binding in [jar:file:/D:/apache-maven-3.6.3/localRepository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]

 

SLF4J: Found binding in [jar:file:/D:/apache-maven-3.6.3/localRepository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.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 [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

 

這是因為與logback的沖突並未解決，導致啟動失敗，根據上面的報錯信息，找到logback-classic-1.2.3.jar和slf4j-log4j12-1.7.25.jar的相應位置刪除，並在pom.xml中加入如下排除代碼：

< dependency >

< groupId > org.springframework.boot </ groupId >

< artifactId > spring-boot-starter-web </ artifactId >

<!-- 排除默認的 logback 日志，使用 log4j-->

< exclusions >

< exclusion >

< groupId > org.springframework.boot </ groupId >

< artifactId > spring-boot-starter-logging </ artifactId >

</ exclusion >

<!--<exclusion>

<groupId>org.slf4j</groupId>

<artifactId>slf4j-log4j12</artifactId>

</exclusion>-->

< exclusion >

< groupId > ch.qos.logback </ groupId >

< artifactId > logback-classic </ artifactId >

</ exclusion >

</ exclusions >

</ dependency >

 

注釋兩者其中的一個就行
