MVN spring-boot:运行抛出log4j错误



我是Java新手。我在执行命令mvn spring-boot: run时遇到错误。有人能帮我解决这个问题吗?截图附在这里

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/langscape/.m2/repository/org/slf4j/slf4j-simple/1.7.28/slf4j-simple-1.7.28.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/langscape/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/langscape/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.12.1/log4j-slf4j-impl-2.12.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]
Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.SimpleLoggerFactory loaded from file:/home/langscape/.m2/repository/org/slf4j/slf4j-simple/1.7.28/slf4j-simple-1.7.28.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.SimpleLoggerFactory

在依赖项中有两个主要问题:

  • 你混合spring-boot-starter-*依赖从几个不同的版本，
  • 你覆盖了一些托管依赖的版本。Spring Boot管理数百个工件的版本(参见完整列表):您不应该为这些工件指定<version>标记。

在这些更改之后，您的Spring Boot依赖项(我假设您想要Log4j 2)。x，而不是Log4j 1.2)变成:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

除此之外，在您的IDE中使用mvn dependency:tree或类似的功能来找出拉log4j(版本1.2)和logback-classic的依赖项，并排除这些传递依赖项。您有一个这样的依赖项:

<dependency>
<groupId>net.sf.okapi.steps</groupId>
<artifactId>okapi-step-tradosutils</artifactId>
<version>0.37</version>
<exclusions>
<exclusion>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</exclusion>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</exclusion>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
</exclusion>
</exclusions>
</dependency>
