springBoot框架集成log4j2框架时,使用idea开发工具,修改pom.xml文件如下:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
1 <!--添加对SpringMVC和Tomcat的依赖--> 2 <dependency> 3 <groupId>org.springframework.boot</groupId> 4 <artifactId>spring-boot-starter-web</artifactId> 5 <exclusions> <!--去除之前对老版本log4j的依赖--> 6 <exclusion> 7 <artifactId>org.springframework.boot</artifactId> 8 <groupId>spring.boot.starter-logging</groupId> 9 </exclusion> 10 </exclusions> 11 </dependency> 12 <!--添加对日志系统的支持,采用最新的log4j2框架--> 13 <dependency> 14 <groupId>org.springframework.boot</groupId> 15 <artifactId>spring-boot-starter-log4j2</artifactId> 16 </dependency>
运行程序出现如下错误:

Logging system failed to initialize using configuration from 'classpath:log4j2.xml' java.lang.IllegalStateException: Logback configuration error detected: ERROR in ch.qos.logback.core.joran.spi.Interpreter@4:13 - no applicable action for [appenders], current ElementPath is [configuration] ERROR in ch.qos.logback.core.joran.spi.Interpreter@6:47 - no applicable action for [Console], current ElementPath is [configuration[Console]] ERROR in ch.qos.logback.core.joran.spi.Interpreter@8:70 - no applicable action for [ThresholdFilter], current ElementPath is [configurationConsole] ERROR in ch.qos.logback.core.joran.spi.Interpreter@10:86 - no applicable action for [PatternLayout], current ElementPath is [configurationConsole] ERROR in ch.qos.logback.core.joran.spi.Interpreter@14:59 - no applicable action for [File], current ElementPath is [configuration[File]]
引用jar时引用了多个logback的框架,由于idea开发工具未根据pom.xml的配置自动配置依赖,未去除之前的log4j的依赖,导致无法解析节点信息。
解决办法:
1、在pom.xml文件中右击选择Diagrams,查看依赖图,找到spring.boot.starter-logging依赖,删除即可。
2、调整<dependency>顺序,pom文件依赖中的顺序问题
在引入的pom坐标下添加了如下排除的依赖。
使用
1 <exclusions> 2 <exclusion> 3 <groupId>包名</groupId> 4 <artifactId>类名</artifactId> 5 </exclusion> 6 </exclusions>
