我目前正在尝试使用log4j/slf4j和Java 11构建应用程序，但是我在运行时遇到了这个问题:
I'm currently trying to build an app with log4j/slf4j and java 11 but I'm facing this problem at runtime:

此代码的起源是我的记录器的初始化:
The code that is at the origin of this is the initialization of my logger:
private static final Logger LOGGER = LoggerFactory.getLogger(NameAsCreated.class);
我依赖于:
- org.apache.logging.log4j:log4j-api:2.11.1
- org.apache.logging.log4j:log4j-core:2.11.1
- org.apache.logging.log4j:log4j-slf4j18-impl:2.11.1
- 依赖于org.slf4j:slf4j-api:1.8.0-beta2的Maven项目
我正在使用Java版本的OSX Mojave:
I'm on OSX Mojave with Java version:
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment AdoptOpenJDK (build 11+28-201810021910)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11+28-201810021910, mixed mode)
有人对我做错了什么以及如何解决这个问题有想法吗?
Does someone have an idea of what I'm doing wrong and how I can solve this?
推荐答案
根据
Log4j支持在其某些组件中使用的JSR 223脚本语言.
Log4j provides support for JSR 223 scripting languages to be used in some of its components. ，正如Java 9中 and as said in the comments by 还请注意，模块 Note also that the module 这篇关于Log4j2/Slf4j和Java 11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！
Alan Bateman的注释中所述，您必须使用--add-modules java.scripting或module-info.java显式添加Java脚本模块.Alan Bateman from Java 9 you have to add explicitly the java scripting module either with --add-modules java.scripting or in module-info.java.jdk.scripting.nashorn是在Java 11中已弃用，并将其删除在将来的版本中.jdk.scripting.nashorn is deprecated in Java 11 and will be removed in a future release.
