首先我们看上面的错误日志

Logging system failed to initialize using configuration from 'classpath:log4j2-dev.xml'java.lang.IllegalStateException: Logback configuration error detected: |
如果只看这两句的话我们可能会认为是我们的日志文件log4j2-dev.xml配置错了，或者路径找不到，其实不然。正解是我们pom文件配置的有问题，jar包存在冲突，下面来看下我们的pom文件吧
pom.xml

上面的pom文件是最初报错时的配置文件，看上面的配置文件貌似没有问题，我们需使用log4j2日志的starter也已经引入了，但是这里我们需要注意一点就是我们在引入spring-boot-starter-web包的时候他里面默认使用了logback日志，这样就会产生日志包的冲突，其实不只是starter-web包默认引入的logback还有很多的包默认引入的logback包，看下图
上图中是这个pom文件的jiar包结构示意图，log4j2部分就是我们新引入的spring-boot-starter-log4j2包，上图中我通过黄线画出了现在系统中所有logback的引入，可以看出所有引用，这里涉及到几个包，分别是web包，mybatis包，jdbc包。那我们现在要解决jar包冲突的问题是不是需要每个包下都排除默认引用的logger日志呢，理论上是完全没有问题的，但是那样岂不是很费事，2种解决办法。

解决办法2
那我只导用了web包，不想导入spring-boot-starter能不能解决呢？

看见第二个解决办法，问题是不是来了。很多包都默认使用的logback,你单独排除了web包是不是还会出现这个问题，
答 ： 是的会出现，这里就需要知道pom文件的加载顺序了，pom文件的加载顺序也是从上至下执行，那么我们就需要把web包放到pom文件中的第一位，在向下执行的时候也会排除所有的默认logger了。
上面就是两种解决办法。希望能给大家一个参考，也希望大家多多支持服务器之家。
