Maven类路径错误多个SLF4J绑定

Question

尝试进行MAVEN INSTALL时出现此错误。我尝试排除，但不确定pom文件中的位置。让我在pom文件中应如何以及应使用哪些排除标签。我还将我的pom文件片段附加在其中，以包括排除项SLF4J：类路径包含多个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]

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中找到绑定.jar！/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J：有关说明，请参见http://www.slf4j.org/codes.html#multiple_bindings。SLF4J：实际绑定的类型为[ch.qos.logback.classic.util.ContextSelectorStaticBinder]

POM文件：

Answer 1

1次

mvn dependency:tree

查看哪个包导入org.slf4j

2保留一个，排除另一个

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

Answer 2

排除默认日志记录的正确方法，并配置 log4j 进行日志记录。在 Spring Boot 项目中添加这个依赖项，如果它还没有的话

<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>
