Mavenjar包冲突的事情解决（亲测效果好、实力佐证）版权声明

1.今天Pom已将依赖项添加到Jar包冲突。
在启动项目时，它将被打包。jar包冲突的问题。在下面SpringBoot以项目为例。
我在Pom.xml已将依赖项添加到文件：

2.启动项目时将报告错误。

3.仔细查看此处报告的错误。
关于日志的两个冲突，我自己使用了它们。log4j，结果是另一个slf4j

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/wangdong/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.7/log4j-slf4j-impl-2.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/wangdong/.m2/repository/ch/qos/logback/logback-classic/1.1.11/logback-classic-1.1.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]

4.定位冲突slf4j在哪里。
通过以下内容查找：

/Users/wangdong/.m2/repository/ch/qos/logback/logback-classic/1.1.11/logback-classic-1.1.11.jar

5.看看下面的红线框jar包裹是刚刚推出的吗
放置刚刚介绍的Maven项目注释，在指南下重新编译包。

6.在第四部分找到了这两个jar包消失，这意味着刚刚添加的依赖项已创建。jar包冲突的问题。

7.所以现在就开始排除依赖。

8.这必须纳入相应的依赖关系
groupId和artifactId请务必遵循IDEA提示符写得正确。

写完9.后，你会发现冲突包不见了，它会得到解决。

最后，再次启动项目，它将获得成功。
