我正在学习教程https://spring.io/guides/gs/actuator-service/

当我尝试运行应用程序时，我得到：

未能实例化所报告的异常: ch/qos/logback/core/joran/spi/JoranException at org.slf4j.LoggerFactory.bind(LoggerFactory.java:150) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:124) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:412) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:357) at org.apache.commons.logging.impl.SLF4JLogFactory.getInstance(SLF4JLogFactory.java:155)在org.apache.commons.logging.impl.SLF4JLogFactory.getInstance(SLF4JLogFactory.java:132) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:273) at org.springframework.boot.SpringApplication.(SpringApplication.java:189) at hello.HelloWorldConfiguration.main(HelloWorldConfiguration.java:11) at : java.lang.ClassNotFoundException: ch.qos.logback.core.joran.spi.JoranException at java.net.URLClassLoader.findClass(URLClassLoader.java:381)在java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) .线程"main“java.lang.NoClassDefFoundError中的更多异常: ch/qos/logback/core/joran/spi/JoranException at org.slf4j.LoggerFactory.bind(LoggerFactory.java:150) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java：在org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:412) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:357) at org.apache.commons.logging.impl.SLF4JLogFactory.getInstance(SLF4JLogFactory.java:155) at org.apache.commons.logging.impl.SLF4JLogFactory.getInstance(SLF4JLogFactory.java:132) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:273) at org.springframework.boot.SpringApplication.(SpringApplication.在hello.HelloWorldConfiguration.main(HelloWorldConfiguration.java:11)引起的: java.lang.ClassNotFoundException: ch.qos.logback.core.joran.spi.JoranException at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) .

我的pom文件如下所示：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
  </build>

</project>

我对如何解决这个问题感到不知所措。我试过打扫和重建，甚至重新进口。我看过类似的问题，如这，但似乎没有任何效果。

让程序运行的唯一方法是将父pom更改为1.3.1.RELEASE版本，但我不想使用这个版本，也不想使用1.4.1.RELEASE。

任何帮助都将不胜感激。

下面是mvn依赖项:tree

更新

如果我加上

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>1.7.5</version>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>

  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>1.7.5</version>
  <scope>runtime</scope>
</dependency>

我得到了

下面的行动对我很有帮助

运行mvn dependency:purge-local-repository以删除所有依赖项并强制重新下载。
然后做一个mvn clean verify

我添加了这个依赖项并解决了问题。

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

如果发生这错误，您只需使用logback-经典版本。

您需要找到log4j并添加类路径。
