这是一个之前被问过的问题,但不幸的是,似乎没有任何解决方案对我有用。我正面临这个异常(使用精简堆栈跟踪):
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$1.getConnection(ThreadSafeClientConnManager.java:221)
at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:401)
at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820)
使用命令行Maven进行编译时以及部署到Tomcat时会发生这种情况。它在IntelliJ IDEA中运行良好。
通常我希望这是由正在使用的SLF4J库的多个版本引起的。但Maven依赖树在单个版本中显示所有slf4j库:
..$ 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
我甚至确保〜/ .m2 / repository
中没有其他JAR没有对commons-logging库的引用(我将它们全部排除在依赖树之外。
如何解决此问题?我的想法已经不多了。

鉴于我最近的实验,它似乎并不是与项目文件有关的问题。我试图'hg bisect'这个问题,但回去几周我找不到一个有效的版本。其中一些在生产系统中运行,因此不太可能是导致此问题的代码更改。

NoSuchMethodError的javadoc说,
通常,编译器会捕获此错误;这个错误可以 只有在类的定义发生不兼容的情况下才会在运行时发生。
所以这可能是由于加载的slf4j版本不兼容造成的。而不是查看类路径并猜测加载类的位置,而不是按照here所述的方式查找类的加载位置。
打印出加载org.slf4j.spi.LocationAwareLogger
,org.apache.commons.logging.impl.SLF4JLocationAwareLog
和org.slf4j.Marker
的位置。

一种解决方案。
验证eclipse目录:configuration \ org.eclipse.equinox.simpleconfigurator \ bundles.info
slf4j没有更多
答案 2 :(得分:1)
做
mvn clean dependency:tree -DskipTests;
删除“org.slf4j”的所有依赖项,除了一个(最高的一个“)

我们遇到了类似的问题,结果发现我们在类路径中有两个不兼容的slf4j jar版本。 类路径具有以下2个不兼容的版本。从类路径中删除较低版本后,问题得到解决。
slf4j-api-1.6.1.jar
SLF4J-log4j12-1.6.1.jar
slf4j-api-1.5.11.jar
slf4j-log4j12-1.5.11.jar
答案 4 :(得分:1)
我有相同的错误消息,但是解决方案对我来说是不同的。我必须删除,以摆脱来自maven pom的依赖:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.6.1</version>
</dependency>
此后错误消失,一切对我都有用。

我的pom文件中有石英调度程序,其中包括slf4j,所以我将其排除在外:
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
并且工作了!
答案 6 :(得分:0)
解决了!!!
我依赖于另一个使用JavaDoc
插件的项目。
JavaDoc
插件内部使用Maven-core
,Maven-core-2.2.1
使用jcl-over-slf4j: 1.5.6
。
Maven-core
是父级jar。
现在,由于这个JCL
jar,我正面临着这个问题。
因此,我将其从lib
weblogic
文件夹(或您可能使用的任何服务器)中删除。
和ALAS !!问题解决了。
注1: - 您还可以使用Maven的<exclusion>
标记从JavaDoc
(或任何其他插件)中删除此依赖关系以解决此问题。
注2: - 使用POM中的Dependency Hierarchy
标签查看是否存在任何此类旧SLF4J
个罐子。并删除休息,只保留一个版本。
希望有所帮助......
答案 7 :(得分:0)
当您具有使用相同传递依赖项的依赖项时,通常会发生这种情况。这意味着您的2个依赖项(或您的应用程序和传递依赖项)都在内部使用不同版本的SLF4J。但是你的应用程序只能同时使用该类的单个版本,所以它必须选择(不知道这里的规则......随机?)
要解决此问题,您通常需要执行mvn dependency:tree
以查看哪些使用不同版本的SLF4J。
添加此依赖项解决了我的问题
