java-module

问题 I've created what I'm pretty sure is a modular jar file. But if possible, I'd like to double check. Given a jar file, is there a way to determine what modules the compiler would find within it? 回答1: The alternative is to use the jar --describe-module ( -d for short), e.g.: jar --file=myjar.jar --describe-module 回答2: You can list the modules within the jar using the following java tool command:- java -p yourModular.jar --list-modules Edit : You shall preferably make use of the jar command lin

问题 I am using ASM 7.0 in a short Java 11 project, which convert a class file to a text using the following code: final var charset = StandardCharsets.UTF_8; final ByteArrayOutputStream bos = new ByteArrayOutputStream(); try (var pw = new PrintWriter(bos, false, charset)) { final org.objectweb.asm.ClassVisitor traceClassVisitor = new TraceClassVisitor(null, new org.objectweb.asm.util.Textifier(), new PrintWriter(bos)); new ClassReader(stream.getStream()).accept(traceClassVisitor, ClassReader.SKIP

问题 Recently I was converting a spring boot(2.1.3 version) dummy project into a spring boot muti module project on java 11. To make it work I have to explicitly add --add-modules=java.instrument as run time vm argument. Please find the related so question here Spring boot multi module project with java 11 throws cannot access class org.springframework.cglib.core.ReflectUtils Then I checked the default modules of my installed jdk using —list-modules and I can see that java.instrument in that.

问题 I'm trying Java 10 development with Spring Boot 2 and I encounter some issues. The application is a simple webapp based upon Spring Boot 2.

问题 My question: How do I set a module path for gradle build ? I've become comfortable working with Java modules from the command line. I do a frequent exercise in Powershell which results in these source files. └───src ├───appMod │ │ module-info.java │ │ │ └───appPack │ Entry.java │ └───greetMod │ module-info.java │ └───greetPack Hello.java appMod/module-info module appMod { requires greetMod; } appMod/appPack.Entry package appPack; import greetPack.Hello; public class Entry { public static void

问题 Let's consider the following situation. There are three layers. BootLayer (moduleA) | |_______Child1(moduleB) | |__________ Child2(moduleC) Child1 is the child of the BootLayer, Child2 is the child of the Child1. Child1 and Child2 was created by the same code: ClassLoader parentClassLoader = ClassLoader.getSystemClassLoader(); ModuleLayer layer = parentLayer.defineModulesWithOneLoader(cf, parentClassLoader); As you see the parent class loader of both child layers is SystemClassLoader. However
