如何解决这个slf4j异常，未找到日志方法

我越来越关注SLF4J异常，我试过从pom.xml中删除slf4j依赖关系，仍然存在，任何人都可以帮忙？如何解决这个slf4j异常，未找到日志方法

例外情况如下：。。。

答案取决于你想要做什么。你想使用slf4j进行日志记录吗？如果是这样，删除它是相当适得其反。显然你的一个依赖使用apache commons logging，但是找不到它的实现。所以*如果你想通过slf4j/logback登录，你必须添加你在你的pom中排除的jcl-over-slf4j依赖。它确保所有jcl事件都通过slf4j进行路由。 – sheltem

是的，我想使用slf4j进行日志记录，因为我得到的错误，该方法没有发现异常，所以我冲浪了互联网，发现错误可能是由于slf4j的多个依赖项，所以我排除所有依赖项slf4j，我仍然我得到这个错误。我有以下的疑问，你可以请澄清.. 因为我想使用slf4j进行日志记录，我也加入了依赖，但由于我得到异常可能是由于多个slf4j版本依赖关系，我认为其他依赖正在下载。我应该排除其他依赖或不？ – Shivagoy

Hi Sheltem，你能帮我解决这个异常吗？因为我被这个异常严重困住了。 – Shivagoy

我假设你正在使用Maven 3.x的因此，添加<dependencyManagement>部分，将POM中配置SLF4J的实际版本（这会去你的父POM所以所有模块使用这些替代）：

<properties> 
    <slf4j.version>1.7.5</slf4j.version> 
</properties> 

<dependencyManagement> 
    <dependencies> 
     <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-api</artifactId> 
     <version>${slf4j.version}</version> 
     </dependency> 
     <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>jcl-over-slf4j</artifactId> 
     <version>${slf4j.version}</version> 
     </dependency> 
     <!-- Since slf4j is a bridge, you need an implementation of it that would 
     redirect all calls to slf4j or JCL. Following is to perform logging using 
     the basic implementation, choose your preferred implementation 
     (it seems you were using logback). --> 
     <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-simple</artifactId> 
     <version>${slf4j.version}</version> 
     <scope>runtime</scope> 
     </dependency> 
    </dependencies> 
</dependencyManagement>

然后，在你的模块的POM，使用在主<dependencies>部分的依赖关系如下（我建议也从其他依赖删除排除时，Maven应该能够选择正确的版本，因为你已经覆盖它）：

<dependencies> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-api</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>jcl-over-slf4j</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-simple</artifactId> 
    </dependency> 
    <!-- Other dependencies --> 
    ... 
</dependencies>

现在执行一个mvn clean install从您的项目的根源。
