什么依赖于 SLF4J 依赖

Question

我运行我的项目使用 spring mvc 和 hibernate，使用 Tomcat 作为服务器。当我运行项目时，我得到了一个错误日志。
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder"
我看到了删除日志的不同解决方案。
但是我找不到任何关于需要这种依赖性的答案。这是休眠或 spring 或 tomcat。为什么需要它？

我的pom.xml

Answer 1

根据经验，使用mvn dependency:tree 命令了解依赖关系。此外，您声明了多个 spring 库，并且还声明了 hibernate 和 spring-orm 而不依赖于 Spring BOM。

可能会导致冲突或版本不兼容（运气好在编译时，运气差则在运行时）。
通过使用 spring boot dependencies bom，您可以避免这种情况，并且还可以解决您的初始问题（缺少 lib）。 Look at that :

13.2.2 Using Spring Boot without the parent POM

Not everyone likes inheriting from the spring-boot-starter-parent POM. You may have your own corporate standard parent that you need to use, or you may just prefer to explicitly declare all your Maven configuration.

If you don’t want to use the spring-boot-starter-parent, you can still keep the benefit of the dependency management (but not the plugin management) by using a scope=import dependency:
<dependencyManagement>
     <dependencies>
        <dependency>
            
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>1.3.8.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
