項目依賴jar衝突，手動排除方案

錯誤描述：如下

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    com.alibaba.dubbo.common.logger.LoggerFactory.setLoggerAdapter(LoggerFactory.java:86)

The following method did not exist:

    com.alibaba.dubbo.common.logger.LoggerAdapter.getLogger(Ljava/lang/String;)Lcom/alibaba/dubbo/common/logger/Logger;

The method's class, com.alibaba.dubbo.common.logger.LoggerAdapter, is available from the following locations:

    jar:file:/C:/Users/Administrator/.m2/repository/org/apache/dubbo/dubbo/2.7.6/dubbo-2.7.6.jar!/com/alibaba/dubbo/common/logger/LoggerAdapter.class
    jar:file:/C:/Users/Administrator/.m2/repository/com/alibaba/dubbo/2.4.10/dubbo-2.4.10.jar!/com/alibaba/dubbo/common/logger/LoggerAdapter.class

It was loaded from the following location:

    file:/C:/Users/Administrator/.m2/repository/org/apache/dubbo/dubbo/2.7.6/dubbo-2.7.6.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of com.alibaba.dubbo.common.logger.LoggerAdapter

 我這裏就是：同時引入了：com.alibaba.dubbo和org.apache.dubbo，項目進行日誌管理，LoggerFactory使用的時候使用的org相關的，但是需要的是com.alibaba.dubbo相關，當然在類似錯誤中也是同理，即：同時引入同類型的JAR，默認使用的不是我們想要的

解決方案：

假設我們同時引入了A，B，但不需要使用A，則在引入A的pom中exclusion就好了，一般這種都是出現在，一個是顯式引入，一個是依賴的二方包引入，在後者裏排除即可。

舉例：

pom中我們同時引入了A，B，同時A裏面引入了C，但是C和我們的B衝突了，此時只需要在A的pom中exclusion就行，如下：

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>A</artifactId>
     <version>1.0.0</version>
        <exclusions>
          <exclusion>
             <groupId>org.junit.vintage</groupId>
             <artifactId>C</artifactId>
          </exclusion>
        </exclusions>
</dependency>
