logback无法生成日志文件

vieyahn2017 commented 3 years ago

这次遇到的是 log4j，slf4j, logback冲突问题

SLF4J: Class path contains multiple SLF4J bindings.

slf4j与logback冲突问题

jyj019 2018-10-20 22:27:23 6195 收藏 2 分类专栏：程序基础文章标签： java 异常版权 slf4j与logback冲突问题最近发现配置日志中slf4j和logback冲突，导致日志无法打出。

SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/.m2/repository/org/slf4j/slf4j-log4j12/1.7.10/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/.m2/repository/ch/qos/logback/logback-classic/1.0.13/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. 发现需要排除logback包，经过检查，发现logback包在opentsdb中。排除后解决问题。

直接粗暴的解决方法：

删除后正常，删除这个：slf4j-log4j12-1.6.1.jar

find /***/softwarepath  -iname slf4j-log4j12-1.7.30.jar -exec rm -rf {} \;

在使用maven管理jar的依赖关系的时候，经常发生jar的不同版本冲突。如何解决呢？

使用命令： mvn dependency:tree 来查看依赖关系树形结构，从中排查冲突的jar。
