Maven类路径错误多个SLF4J绑定

Question

我在尝试安装MAVEN时遇到了这个错误。我尝试了排除，但不确定在pom文件中包含的位置。让我在我的pom文件中应该包括怎样和什么排除标记。我还附加了我的pom文件片段，其中包括排除'SLF4J:Class path包含多个SLF4J绑定。

SLF4J:在[jar:file:/c:/users/147188/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar！/org/slf4j/impl/staticloggerbinder.class]中找到绑定

SLF4J:在[jar:file:/c:/users/147188/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.10.0/log4j-slf4j-impl-2.10.0.jar！/org/slf4j/impl/staticloggerbinder.class]中找到绑定

SLF4J:请参阅http://www.slf4j.org/codes.html#multiple_bindings获得解释。SLF4J:实际绑定的类型为[ch.qos.logback.classic.util.ContextSelectorStaticBinder]

POM文件：

<!-- Start of required part to make log4j work -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>

Answer 1

排除默认日志记录的正确方法，并将log4j配置为日志记录。在spring boot项目中添加此依赖项，如果它还不存在

<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>

参见spring日志记录-如何。

Answer 2

1次运行

mvn dependency:tree

查看哪个包导入org.slf4j

2保留一个，排除其他

   <exclusion>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
    </exclusion>
