问题 Is there a way to bundle the JRE with jlink if not all or even none of the application's dependencies are yet modularized? I do understand that this does not lead to trimmed runtimes but still, I want to bundle a JRE with my application, even untrimmed. 来源： https://stackoverflow.com/questions/53314512/jigsaw-bundling-jre-with-automatic-modules

问题 I want to switch from Oracle JDK 8 to Open JDK 11 using Eclipse 2018-12. I have the following situation: In my Eclipse workspace I have a main maven project called example with some maven dependencies my_dependency_1, my_dependency_2 that are also maven projects in the same workspace. Currently, only example is modular (and thus contains a module-info.java ). The other projects are non-modular and are included in the pom.xml as well as required (automatic) modules in the module-info.java of

问题 When trying to launch the JavaFX "Hello world" sample, the native libraries are not found -- or, they are rejected. The symptom is a "No toolkit found" exception. There seems to be some specificity to macOS, as signing is mentioned at some point. What I did (on macOS 10.14.6): Installed Java 12 from https://adoptopenjdk.net Downloaded the JavaFX 12 SDK for macOS from http://gluonhq.com/download/javafx-12-0-2-sdk-mac. Unzipped it as $WRK_DIR/javafx-sdk-12.0.2 Downloaded the JavaFX "hello world

问题 I tried to find any mention of handling of compression in new Java HTTP Client but failed. Is there a built-in configuration to handle for e.g. gzip or deflate compression? I would expect to have a BodyHandler for e.g. something like this: HttpResponse.BodyHandlers.ofGzipped(HttpResponse.BodyHandlers.ofString()) but I don't see any. I don't see any configuration in HttpClient either. Am I looking in the wrong place or was this intentionally not implemented and deferred to support libraries?

问题 I have an application, that uses Spring Boot and Spring Data JPA with annotation-only based configuration for its persistence layer. I've started migrating this application to the latest Spring Boot version (2.1.x) along with Java (OpenJDK) 11. After configuring the module descriptors, the application starts up, but when Spring reaches the point where it wants to build up the persistence layer, the application stops with the following exception: Caused by: javax.persistence

问题 I'm new to the Java 11 HttpClient and would like to give it a try. I have a simple GET request that return JSON and I would like to map the JSON response to a Java class called Questionnaire . I understand that I can turn the response out of box into a String or an input stream like this HttpRequest request = HttpRequest.newBuilder(new URI(String.format("%s%s", this.baseURI, "/state"))) .header(ACCEPT, APPLICATION_JSON) .PUT(noBody()).build(); HttpResponse<String> response = this.client.send

问题 OS: Linux Mint 18.3, Eclipse "2019-06". Gradle wrapper using Gradle 5.4. Yesterday I spent about 4 hours trying to put together a project in Eclipse which would actually run and display a JavaFX Scene when using Java 11. I managed it in the end due to help from here. But this was just a bog-standard "Java project" in Eclipse. What I actually need to do is develop a Gradle project, using Groovy as the main language. Again, from the same gentleman, José Pereda, I found this answer. This does a

问题 Hi I am new with java modules so this might be a dumb question. I was trying to sign my jar file with keystore and got the following error. user@Ubuntu:libs(master)$ jarsigner -keystore keyStoreFileName Test.jar alias Enter Passphrase for keystore: jarsigner: unable to sign jar: java.util.zip.ZipException: duplicate entry: module-info.class I couldn't find any documentation of how to avoid this. So I did jar -tf to check the content of the jar and yes, it does have multiple module-info.class
