我正在尝试使用 sfl4j 和 log4j 在 Spring 中构建应用程序。我阅读并完成了有关从 spring-context 中删除 commons-logging 的所有说明。但是我不断收到同样的错误：

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListenerjava.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V

有人可以帮忙吗？我花了几天时间试图弄清楚这一点。

@Solubris，您给了我正确的指示。根据我对您帖子的回复，它最初不起作用，因为我没有删除仍然在 lib 文件夹中的任何相关的 slf4j.version 旧 jar。因此，当我删除所有这些重复的库时，Web 应用程序部署得很好。

对于遇到相同问题的任何人，请遵循 Solubris 解决方案，然后...确保检查您的 lib 文件夹并删除任何具有旧版本的 slf4j 相关 jar。我希望这可以为人们节省无数小时的疑惑和疯狂！

我在 /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/ex 中找到了以下文件 slf4j-api-1.5.6.jar
slf4j-log4j12-1.5.6.jar

因此，我删除了这些以支持 maven 在存储库（.../.m2/repository）中安装的那些，从而解决了问题。

解决问题的最佳方法是为您的 log4j 库和研究调用链包含源文件。

  • 确保 log4j 和 jcl-over-slf4j 成功部署在 Tomcat 上。
  • 对 log4j-api和jcl-over-lsf4j使用grepcode来分析问题根源并解决版本兼容性问题。
  • 确保您的类路径中没有冲突。使用下一个片段确保您从库 jar 中加载了类：

例子：

    Class klass = String.class;
    URL location = klass.getResource('/'+klass.getName().replace('.', '/')+".class");

将打印这种类型的字符串：

    jar:file:/Users/taky/.gradle/caches/artifacts-14/filestore/com.google.inject/guice/3.0/jar/9d84f15fe35e2c716a02979fb62f50a29f38aefa/guice-3.0.jar!/com/google/inject/internal/InjectorImpl.class

您缺少 slf4j api 的依赖项：

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>${slf4j.version}</version>
    </dependency>

这定义了 slf4j 的 api（接口），其他依赖项实现了 api。

我建议使用 logback 作为实现： http: //logback.qos.ch/reasonsToSwitch.html

这是使用带有 logback 的 slf4j 的完整配置：

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>${slf4j.version}</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>log4j-over-slf4j</artifactId>
        <version>${slf4j.version}</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>${slf4j.version}</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jul-to-slf4j</artifactId>
        <version>${slf4j.version}</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.0.6</version>
    </dependency>

最后，您需要将其添加到您的 logback.xml 以通过 slf4j 引导 jul：

<!-- support for jul through logback: http://logback.qos.ch/manual/configuration.html#LevelChangePropagator -->
<contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator"/>
