问题 I'm working on project on IntelliJ IDEA and I want to add support to Extensible Applications in my java application. The way to do it is, creating a jar file in this jar file there should be a META-INF/services directory, inside this directory, I need to add a file whose name contains the same name as the fully-qualified name of the interface which provides the service, and in that file it should have the fully-qualified name of the implementations of that interface. This is the encrypt and

问题 I would like to be able to indicate an enum type as an interface implementation and then load all enums as separate instances/implementations of the interface via the ServiceLoader API. An example of this use case would be to allow downstream users of my API to specify custom values, but provide an enum with standard/common implementations. My interface only requires a String name() , so any enum implements it already. For example, the CopyOption interface in the Java NIO APIs, with the

问题 I have a question about how the serviceloader changed in Java 9 based on this scenario Scenario Project gert Class Main package gert; import java.io.ByteArrayInputStream; import java.io.InputStream; import java.nio.charset.StandardCharsets; import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBException; import javax.xml.bind.Unmarshaller; public class Main { static public void test() throws JAXBException { InputStream is = new ByteArrayInputStream("<Classes RUNTIME_INCLUDE_JARS=\"\">

问题 I just read about Java 9 module system and I'd like to ask about ServiceLoader. Is there any way how to add service implementation when the application is already started? How about removing some service implementation? Use case: I will have some application that calculates something. The calculation algorithm will be defined in some service(Java 9 module). Are there any steps that can be done to replace this algorithm without stopping the application? When will I replace the jars is it just

问题 I am writing a web app in Eclipse. I am trying to use the ServiceLoader class to load some plugins. The docs for ServiceLoader say I need to place a file in META-INF/services. I have placed the file in the WebContent/META-INF/service folder but when I run the JUnit test via Eclipse it does not find any plugins. Is this the correct location for the file? Also, how can I get more debug info from ServiceLoader such as the folders it is searching for the file in? 回答1: The META-INF/services should
