bug产生原因

开发中，遇到需要在项目中，引入海康开放平台demo，将代码及sdk全部引入后，pom.xml加上如下依赖。

<dependency>
     <groupId>com.hikvision.ga</groupId>
     <artifactId>artemis-http-client</artifactId>
     <version>1.1.3</version>
</dependency>

运行起来！！！
海康demo可以正常弹框如图。

但是，原来可以运行的项目不能正常启动了？？？？
出现了下面的bug。。。。。

2022-02-27 15:53:06.317 [ INFO] [main] [org.springframework.core.KotlinDetector.<clinit>(KotlinDetector.java:57)] - Kotlin reflection implementation not found at runtime, related features won't be available.

添加Kotlin 相关依赖

<dependency>
     <groupId>org.jetbrains.kotlin</groupId>
     <artifactId>kotlin-reflect</artifactId>
     <version>1.6.10</version>
     <scope>runtime</scope>
 </dependency>

添加Kotlin依赖后，bug少了一个了！！！如图

exclusion logback-classic

bug中是这样写道的：LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. 经过各种资料查询后，应该是海康demo中引用的日志依赖和我们原本项目中所应用的依赖不同导致的，可以这样解决下。
首先可以在pom.xml文件中右键，Maven–> Show Dependencies… 可以看到项目中依赖图。CTRL+F查找到logback-classic，移除该依赖属性。或可直接在pom中进行修改，如下。加入…部分内容。

  <dependency>
            <groupId>com.hikvision.ga</groupId>
            <artifactId>artemis-http-client</artifactId>
            <version>1.1.3</version>
            <exclusions>
                <exclusion>
                    <artifactId>logback-classic</artifactId>
                    <groupId>ch.qos.logback</groupId>
                </exclusion>
            </exclusions>
        </dependency>

再次运行项目，看能成功吗？？？
新的bug出现了。。。

exclusion logback-core

这一次，只需在pom.xml中继续exclusion一次就可以了！！，加入如下代码，再次运行！

 
<exclusion>
       <groupId>ch.qos.logback</groupId>
       <artifactId>logback-core</artifactId>
</exclusion>

项目成功运行！！

	   <dependency>
            <groupId>com.hikvision.ga</groupId>
            <artifactId>artemis-http-client</artifactId>
            <version>1.1.3</version>
            <exclusions>
                <exclusion>
                    <artifactId>logback-classic</artifactId>
                    <groupId>ch.qos.logback</groupId>
                </exclusion>

            </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.jetbrains.kotlin</groupId>
            <artifactId>kotlin-reflect</artifactId>
            <version>1.6.10</version>
            <scope>runtime</scope>
        </dependency>

主要是pom.xml文件的配置，需要排除log的引入不同，需要添加的全部依赖，如上。
