ClassNotFoundException: org.slf4j.impl.StaticLoggerBinder

Question

我正在使用boot-starter-parent版本将spring应用程序转换为spring-boot：2.0.4.RELEASE。当我使用 mvn 安装，它运行良好，但是当我尝试使用命令运行应用程序时：mvn spring-boot:run -Dspring.profiles.active=dev，我收到此异常： ClassNotFoundException： org.slf4j.impl.StaticLoggerBinder

以下是我的pom中的依赖项：

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
<version>2.0.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.24</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.3.0-alpha4</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.3.0-alpha4</version>
</dependency>
</dependencies>

我尝试遵循这个问题的建议，并使用新版本和旧版本的 logback(核心和经典)依赖项，并添加"slf4j-log4j12"和"slf4j-simple"，但仍然得到异常。堆栈跟踪是：

java.lang.NoClassDefFoundError： org/slf4j/impl/StaticLoggerBinder at org.springframework.boot.logging.logback.LogbackLoggingSystem.getLoggerContext (LogbackLoggingSystem.java：285) at org.springframework.boot.logging.logback.LogbackLoggingSystem.beforeInitialize (LogbackLoggingSystem.java：102) at org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationStartingEvent (LoggingApplicationListener.java：191) at org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationEvent (LoggingApplicationListener.java：170) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener (SimpleApplicationEventMulticaster.java：167) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent (SimpleApplicationEventMulticaster.java：139) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent (SimpleApplicationEventMulticaster.java：122) at org.springframework.boot.context.event.EventPublishingRunListener.start (EventPublishingRunListener.java：68) at org.springframework.boot.SpringApplicationRunListeners.start (SpringApplicationRunListeners.java：48) at org.springframework.boot.SpringApplication.run (SpringApplication.java：316) at org.springframework.boot.SpringApplication.run (SpringApplication.java：1258) at org.springframework.boot.SpringApplication.run (SpringApplication.java：1246) at com.hbo.esp.MyApplication.main (MyApplication.java：17) at sun.reflect.NativeMethodAccessorImpl.invoke0 (Native Method)

Answer 1

尝试更改每个依赖项的版本，如下所示。

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.25</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.2.3</version>
</dependency>

希望这有帮助。
