SLF4J / SLF4J-550 JPMS 下 java.lang.ClassLoader#getResource 工作差异 ============================== Here's what changed in this issue in the last few minutes. This issue has been created This issue is now assigned to you. This issue has been deleted ============================== Issue created ------------------------------ 琉璃 created this issue on 26/May/22 7:57 PM Summary: JSPM 下 java.lang.ClassLoader#getResource 工作差异 Issue Type: Story Affects Versions: 2.0.0-alpha7 Assignee: SLF4J developers list Attachments: 2022-05-27_01-55-40.jpg Components: slf4j-simple Created: 26/May/22 7:57 PM Environment: 版本 Windows 11 专业版版本 21H2 安装日期 ‎2021-‎10-‎15 操作系统版本 22000.675 java 17 2021-09-14 LTS Java(TM) SE Runtime Environment (build 17+35-LTS-2724) Java HotSpot(TM) 64-Bit Server VM (build 17+35-LTS-2724, mixed mode, sharing) Apache Maven 3.8.4 (9b656c72d54e5bacbed989b64718c159fe39b537) Maven home: C:\usr\tool\apache-maven-3.8.4 Java version: 17, vendor: Oracle Corporation, runtime: C:\usr\lib\jdk-17 Default locale: zh_CN, platform encoding: GBK OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows" <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>2.0.0-alpha7</version> </dependency> Priority: Major Reporter: 琉璃 Description: 有如下简单测试代码: There are the following simple test codes: {code:java} package cn.test.resources; import java.net.URL; public class Main { public static void main(String[] args) { URL resource = Main.class.getClassLoader().getResource(""); System.out.println(resource.getFile()); } } {code} 这是一个 maven 项目, 只有这一个文件, pom 文件仅包含 `slf4j-api` 的依赖. 如果不添加 `module-info.java` 文件, 在我的计算机上, 上述代码输出: {color:#c1c7d0}/C:/test/testJpmsResource/target/classes/{color} 如果添加了 `module-info.java` 文件, 即使没有声明 `requires org.slf4j` 我会得到下面的结果: {color:#c1c7d0}file:/C:/usr/data/maven/org/slf4j/slf4j-api/2.0.0-alpha7/slf4j-api-2.0.0-alpha7.jar!/META-INF/versions/9/{color} This is a maven project. There is only one file. The POM file only contains the dependencies of 'slf4j API' If you don't add ` module info Java file, on my computer, the above code output: {color:#c1c7d0}/C:/test/testJpmsResource/target/classes/{color} If you add ` module info Java file, even if it does not declare 'requires org Slf4j ` I will get the following results: {color:#c1c7d0}file:/C:/usr/data/maven/org/slf4j/slf4j-api/2.0.0-alpha7/slf4j-api-2.0.0-alpha7.jar!/META-INF/versions/9/{color} ---- 差异大概发生在 `jdk.internal.loader.BuiltinClassLoader#findMiscResource` , 我的疑问是是什么造成这种差异? , slf4j 的 `META-INF/versions/*` 的文件为什么会在这里返回? The difference probably occurs in `jdk.internal.loader.BuiltinClassLoader#findMiscResource`, my question is: - What makes this difference? - why does slf4j's' meta-inf / versions / * 'file return here? ============================== Issue deleted ------------------------------ Ceki Gülcü has deleted this issue on 26/May/22 8:05 PM ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)

[JIRA] Updates for SLF4J-548: Loading services (plugins) with the caller's ClassLoader

SLF4J / SLF4J-548 [Open] Loading services (plugins) with the caller's ClassLoader ============================== Here's what changed in this issue in the last few minutes. There is 1 comment. View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-548 ============================== 1 comment ------------------------------ pierre on 01/May/22 10:32 PM Hi Ceky, I have read the article [Taxonomy of class loader issues encountered when using Jakarta Commons Logging|https://articles.qos.ch/classloader.html], it seems the problem with JCL's ClassLoader stems from the fact that it uses a Child-first ClassLoader delegation model. I don't want to use a Child-first ClassLoader, I'd like to use the standard Java SDK Parent-first delegation model, but without breaking the extension of the CLASSPATH through ClassLoader inheritance. I don't know enough about Java and ClassLoader, but it seems to me that using the caller's ClassLoader or changing the current.Thread ClassLoader is the same thing. In any case currently it is not possible to load an application using Slf4j and a Service Provider other than using the JRE bootstrap's ClassLoader. (ie: java -cp myapp.jar) ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
