Spring Boot 日誌問題記錄

引言

　　本文主要記錄一下，在新建java工程時，添加依賴文件，引入須要的包，簡單寫了點代碼進行發佈的時候，遇到spring-boot啓動報錯的問題。

問題描述

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/admin/.m2/repository/org/slf4j/slf4j-log4j12/1.7.26/slf4j-log4j12-1.7.26.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/admin/.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/admin/.m2/repository/org/slf4j/slf4j-log4j12/1.7.26/slf4j-log4j12-1.7.26.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

進程已結束，退出代碼 1

　　看到錯誤「LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback」 大概的意思是 能夠remove掉logbacj解決問題。

解決方案

 

 　　修改pom.xml中，排除logback後，啓動一些正常。
