URLClassLoader.addURL（URL）是否遵守META-INF / MANIFEST.MF [英] Does URLClassLoader.addURL(URL) honor the META-INF/MANIFEST.MF

问题描述

如果我的jar包含 MANIFEST.MF 中的Class-Path条目。如果我将jar添加到 URLClassLoader ，那么 Class-Path 条目中的jar也会添加到类加载器？我是否需要内省我想要添加到类加载器的jar来检测它并为每个jar调用 addURL 它们（递归地）？

If I have a jar that includes a Class-Path entry in the MANIFEST.MF. If I add the jar to a URLClassLoader, are the jars in the Class-Path entry also added to the classloader? Do I need to introspect the jars that I want to add to the classloader to detect this and call addURL for each of them (recursively)?

推荐答案

它根据sun.misc.URLClassPath的源代码从JDK 1.6开始，但它没有指定，所以请选择; - ）

It does as of JDK 1.6 according to the source code of sun.misc.URLClassPath, but it isn't specified, so take your pick ;-)
