LocationAwareLogger 上的 SLF4J NoSuchMethodError [英] SLF4J NoSuchMethodError on LocationAwareLogger

问题描述

这是一个以前被问过的问题，但不幸的是，似乎没有解决方案对我有用.我正面临这个异常(带有删节的堆栈跟踪):

This is a question that has been asked before, but unfortunately no solution seems to work for me. I am facing this exception (with abridged stack trace):

java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
    at org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug(SLF4JLocationAwareLog.java:133)
    at org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager$1.getConnection(ThreadSafeClientConnManager.java:221)
    at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:401)
    at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820)

在使用命令行 Maven 进行编译以及部署到 Tomcat 时都会发生这种情况.它在 IntelliJ IDEA 中运行良好.

This happens when compiling using a command line Maven and also when deploying to Tomcat. It works fine inside IntelliJ IDEA.

通常我认为这是由正在使用的 SLF4J 库的多个版本引起的.但是 Maven 依赖树在一个版本中显示了所有 slf4j 库:

Usually I would expect this to be caused by multiple versions of the SLF4J library being in use. But the Maven dependency tree shows all slf4j libraries in a single version:

..$ mvn dependency:tree | grep slf4j
[INFO] +- org.slf4j:slf4j-simple:jar:1.6.4:compile
[INFO] |  - org.slf4j:slf4j-api:jar:1.6.4:compile
[INFO] +- org.slf4j:slf4j-api:jar:1.6.4:compile
[INFO] +- org.slf4j:jcl-over-slf4j:jar:1.6.4:compile
[INFO] +- org.slf4j:slf4j-simple:jar:1.6.4:compile

我什至确保 ~/.m2/repository 中没有其他 JAR

I even ensured that there is no other JAR in ~/.m2/repository

也没有对 commons-logging 库的引用(根据依赖关系树的确认，我将它们全部排除在外.

There are no references to commons-logging libraries either (I excluded them all as confirmed by the dependency tree.

我该如何解决这个问题?我的想法快用完了.

How can I resolve this issue? I'm running out of ideas.

根据这里的要求，完整的依赖关系，首先是父 POM:

这些是在父级上设置的属性:

These are the properties set on the parent:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <org.hibernate.validator.version>4.2.0.Final</org.hibernate.validator.version>
    <org.slf4j.backend>slf4j-simple</org.slf4j.backend>
    <org.slf4j.version>1.6.4</org.slf4j.version>
    <org.springframework.version>3.0.5.RELEASE</org.springframework.version>
</properties>

不过，鉴于我最近的实验，这似乎不是与项目文件有关的问题.我试图将问题一分为二"，但几周前我找不到有效的版本.其中一些正在生产系统中运行，因此不太可能是代码更改导致此问题.

Given my recent experiments it doesn't seem to be an issue relating to the project files, though. I tried to 'hg bisect' the problem, but going back weeks I could not find a version that works. Some of these are running in production systems, so it is not likely to be a code change that causes this problem.

推荐答案

NoSuchMethodError 的 javadocs 说，

The javadocs for NoSuchMethodError say,

正常情况下，这个错误是被编译器捕捉到的；这个错误可以仅在类的定义发生不兼容更改时才会在运行时发生.

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

所以这可能是由于加载的 slf4j 版本不兼容造成的.与其查看类路径并猜测类的加载位置，不如按照 这里.

So this is probably being caused by incompatible versions of slf4j being loaded. Rather than looking at your classpath and guessing where classes are loaded, find where your class is loaded as described here.

打印出 where org.slf4j.spi.LocationAwareLogger、org.apache.commons.logging.impl.SLF4JLocationAwareLog 和 org.slf4j.Marker正在加载.

Print out where org.slf4j.spi.LocationAwareLogger, org.apache.commons.logging.impl.SLF4JLocationAwareLog and org.slf4j.Marker are being loaded from.

这篇关于LocationAwareLogger 上的 SLF4J NoSuchMethodError的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
