java.lang.AbstractMethodError:org.slf4j.impl.Log4jLoggerAdapter.log（ava/lang/Object；Ljava/lang/Throwable；）V

我正在尝试使用samll Camel应用程序，但log4j相关错误即将出现。我在许多论坛上进行了检查，但不幸没有使用。请帮助我解决此问题。提前感谢

要工作，SLF4J的api版本及其绑定版本应兼容（通常为同一版本）

在运行时，使用的SLF4J绑定是1.5.8，但加载的SLF4J API是1.6/1.7版本：

SLF4J:您的SLF4J绑定请求的版本1.5.8不可用 与[1.6,1.7]兼容

您可能有一个可传递的依赖项，该依赖项会拉取SLF4J的1.6/1.7API版本。
您还可以在运行时使用的类路径中指定这个jar。 两个都选中。

---

要检查Gradle项目的依赖关系，您可以使用

Gradle app:dependencies

获取Gradle项目的依赖关系树。

我看不出问题：您的stacktrace显示

SLF4J：您的SLF4J绑定请求的版本1.5.8与[1.6,1.7]不兼容。

，它从字面上描述了这个问题。你看到为你打印的异常了吗？谢谢@Nathan，这很有用。谢谢你的回答，那么我必须使用java 8的哪个版本？我从gradle dependency+--org.slf4j:slf4j api:1.7.6 | | \--org.slf4j:jcl-over-slf4j:1.7.6 | | \--org.slf4j:slf4j api:1.7.6更新1.7.6而不是1.5.8后运行良好的hanks获得以下信息
