Spring-Boot啟動報錯java.lang.NoClassDefFoundError: ch/qos/logback/classic/turbo/TurboFilter

今天搭建項目的時候啟動報錯，java.lang.NoClassDefFoundError: ch/qos/logback/classic/turbo/TurboFilter

具體錯誤如下：

百度到的大部分是缺少包，比如解決辦法引入jar包，但是我啟動還是報錯，那我就繼續百度。

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>

其中這篇文章給我了啟發：https://blog.csdn.net/qq_35981283/article/details/73161921

我是里面的包沖突，當然按照里面的辦法我也能解決，但是略有不同。

看我的pom文件

   1、這是最開始的配置，啟動不不錯，但是無現在不用mongodb了，我就刪掉了A但是啟動就報錯
   A     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

    B    <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

后來改成如下這樣就不報錯了。

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
             <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
所以是包沖突的問題，改了就好了
