SLF4J的NoSuchMethodError

Question

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上下文中删除commons-logging的所有说明。 但是我继续得到同样的错误：

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？ 我花了几天的时间试图解决这个问题。

Answer 1

@Solubris，您给了我正确的指导。 根据我对您的帖子的回复，最初它没有用，因为我没有在lib文件夹中删除任何相关的slf4j.version旧jar。 因此，当我删除所有这些重复的库时，Web应用程序部署就很好了。

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文件夹并删除所有具有较早版本的slf4j相关jar。 我希望这可以节省某人无数小时的疑惑和疯狂！

Answer 2

解决问题的最佳方法是包括log4j库的源文件和研究调用链。

• 确保log4j和jcl-over-slf4j已成功部署在Tomcat上。
• 将grepcode用于log4j-api和jcl-over-lsf4j可以分析问题根并解决版本兼容性。
• 确保您的类路径中没有冲突。 使用下一个代码段，以确保您从库jars中加载了类：

例：

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

将打印此类型的字符串：

    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

Answer 3

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

这是将slf4j与logback一起使用的完整配置：

    <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logback.xml中，以通过slf4j来控制jul：

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

Answer 4

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

因此，我删除了这些，转而使用maven在存储库（... /。m2 / repository）中安装的那些文件，从而解决了问题。
