Question

我正在使用boot-starter-parent版本2.0.4.RELEASE将spring应用程序转换为spring-boot。当我使用构建 mvn install，运行顺利，但是当我尝试使用命令mvn spring-boot:run -Dspring.profiles.active=dev运行该应用程序时，出现此异常： ClassNotFoundException：org.slf4j.impl.StaticLoggerBinder

这是我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this question的建议，并使用新旧版本的logback（核心和经典）依赖项，并添加了“ slf4j-log4j12”和“ slf4j-simple”，但仍然得到了例外。堆栈跟踪为：

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

尝试如下更改每个依赖项的版本。

<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>

希望这会有所帮助。
