Spring Boot - NoClassDefFoundError：ch/qos/logback/classic/Level

问题描述 投票：0回答：10

我创建了一个普通的 Spring Boot 应用程序 (

1.5.9.RELEASE
)，但是当我 
Run As -> Spring Boot App
（在 Eclipse Oxygen 中）时，我得到 

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

应用程序

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CourseApiApp {

    public static void main(String[] args) 
    {
        SpringApplication.run(CourseApiApp.class, args);
    }
}

备注

我也尝试过

mvn clean package
- > 
java -jar target/boot-demo.jar
这给了我

扩展 Mark Bramnik 的答案，看起来确实没有 logback，这很奇怪，因为 

spring-boot-starter-web
依赖于 
spring-boot-starter-logging
。只需尝试将 
spring-boot-starter-logging
添加到您的 POM 文件中

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：

请尝试添加类似的内容（根据 Spring Boot 版本，可能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>

然后您可能需要配置记录器、附加程序等。有关登录 Spring Boot 的更多信息，请阅读官方 Spring Boot 文档中的一章。

这对我有用，但不是很聪明：从 .m2 文件夹中删除了 ch 文件夹，并从 Eclipse 中执行了“运行”>“Maven 安装”。

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。

Spring boot 应用程序需要 logback classic 依赖项。由于无法在类路径中找到 logback-classic jar，因此会抛出错误 引起原因：java.lang.NoClassDefFoundError：ch/qos/logback/classic/turbo/TurboFilter。

添加以下依赖项后，应用程序启动时没有任何问题。

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.11</version>
</dependency>

从 Maven 存储库中删除所有内容并在 Eclipse 中更新项目对我有用。

删除.m2目录中的ch文件夹并更新eclipse项目中的maven项目可以帮助我解决这个问题。

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <!-- <version>${logback.version}</version> -->
    </dependency>

显式添加此 logback 解决了我的问题。

对于我们来说，

java.lang.ClassNotFoundException: ch.qos.logback.classic.joran.JoranConfigurator
意味着“我已经排除了 spring-boot-starter-logging，但需要添加 
spring-boot-starter-log4j2
”或类似的东西，显然。

工作pom：

<build>
<dependencies>
    <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-log4j2</artifactId></dependency>

  <dependency>
     ...something internal
         <exclusions>
        <exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-logging</artifactId></exclusion>
      </exclusions>

根据https://docs.spring.io/spring-boot/docs/2.0.x/reference/html/howto-logging.html如果你想使用log4j而不是logback，你应该“排除“ spring-boot-starter-logging 所以我想必须从每个依赖应用程序中拒绝它的模式并不遥远。虽然有点奇怪...

所以也许发生的情况是，如果你“只是排除”，也许他们仍然引入“只是 logback”（没有 joran）作为单独的依赖项，这让 Spring Boot 感到困惑？

出现错误“NoClassDefFoundError：ch/qos/logback/classic/Level”： 添加以下依赖：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.6.4</version>
</dependency>
