Extending Mark Bramnik answer, It does look like you don't have logback, which is pretty weird because spring-boot-starter-webhave a dependency on spring-boot-starter-logging. Just try to add spring-boot-starter-loggingto your POM file
扩展 Mark Bramnik 的回答，看起来你没有 logback，这很奇怪，因为spring-boot-starter-web依赖于spring-boot-starter-logging. 只需尝试添加spring-boot-starter-logging到您的 POM 文件中
回答by Mark Bramnik
It looks like you're trying to use a logback logging implementation but don't have a logback jar in the classpath:
看起来您正在尝试使用 logback 日志记录实现，但类路径中没有 logback jar：
Please try adding something like this (depending on Spring Boot version there can be another actual version of logback dependency)
请尝试添加这样的东西（取决于 Spring Boot 版本，可能会有另一个实际版本的 logback 依赖项）
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.11</version>
</dependency>
Then you'll probably want to configure loggers, appenders and so forth. For more information about logging in spring boot read a chapter from official Spring Boot documentation.
然后你可能想要配置记录器、附加器等等。有关登录Spring Boot 的更多信息，请阅读Spring Boot 官方文档中的一章。

Apparently I had a broken jar in the classpath, after removing everything from .m2 and updating it worked.
显然，在从 .m2 中删除所有内容并更新它后，我的类路径中有一个损坏的 jar。
回答by nslangde
Removing everything from maven repo and updating project in eclipse worked for me.
从 maven repo 中删除所有内容并在 eclipse 中更新项目对我有用。
回答by apoorv kapil
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<!-- <version>${logback.version}</version> -->
</dependency>
Adding this logback explicitly, solved the issue in my case.
明确添加此 logback，解决了我的问题。
回答by Sobin George
This worked for me, though not very intelligent: Deleted the ch folder from within .m2 folder, and did a Run > 'Maven install' from Eclipse.
这对我有用，虽然不是很聪明：从 .m2 文件夹中删除了 ch 文件夹，并从 Eclipse 中执行了 Run > 'Maven install'。
回答by arjun ganta
Deleting ch folder in .m2 directory and update maven project in eclipse project helps me in fixing this issue.
删除 .m2 目录中的 ch 文件夹并更新 eclipse 项目中的 maven 项目有助于我解决这个问题。

Spring boot application is expecting logback classic dependency.Since its unable to find the logback-classic jar in classpath its throwing an error Caused by: java.lang.NoClassDefFoundError: ch/qos/logback/classic/turbo/TurboFilter.
Spring boot 应用程序期望 logback 经典依赖项。由于它无法在类路径中找到 logback-classic jar，因此引发错误：java.lang.NoClassDefFoundError: ch/qos/logback/classic/turbo/TurboFilter。
After adding the below dependency application started without any issues.
添加以下依赖项应用程序启动后没有任何问题。
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.11</version>
</dependency
