运行 jar 时无法将资源作为流读取

Question

我正在使用 NanoHTTPD 作为我的应用程序服务器，并且在 IDE 中一切正常。当我运行相同的代码形式 jar（使用 maven-assembly-plugin 生成）时，资源未加载。我的应用服务器代码：public class HintTestAppServer extends NanoHTTPD {private HintTestAppServer() throws IOException {    super(8000);    start(NanoHTTPD.SOCKET_READ_TIMEOUT, false);    System.out.println("Running on port " + super.getListeningPort() + "\n");}public static void main(String[] args) {    try {        new HintTestAppServer();    } catch (IOException ioe) {        System.err.println("Couldn't start server:\n" + ioe);    }}@Overridepublic Response serve(IHTTPSession session) {  //below line always return null fot the buffered input stream    BufferedInputStream bufferedInputStream = (BufferedInputStream)            Thread.currentThread().getContextClassLoader().getResourceAsStream("web/" + session.getUri());    String mimeType;    try {        mimeType = URLConnection.guessContentTypeFromStream(bufferedInputStream);    } catch (IOException e) {        e.printStackTrace();        return newFixedLengthResponse("ERROR");    }    try {        return newFixedLengthResponse(Response.Status.OK, mimeType, bufferedInputStream, bufferedInputStream.available());    } catch (IOException e) {        e.printStackTrace();        return newFixedLengthResponse("ERROR");    }}}我的 pom.xml 程序集插件：            <plugin>            <groupId>org.apache.maven.plugins</groupId>            <artifactId>maven-assembly-plugin</artifactId>            <version>3.1.1</version>            <configuration>                <descriptorRefs>                    <descriptorRef>jar-with-dependencies</descriptorRef>                </descriptorRefs>                <archive>                    <manifest>                        <addClasspath>true</addClasspath>                        <mainClass>server.HintTestAppServer</mainClass>                    </manifest>                </archive>            </configuration>

Answer 1

找出解决方案是：

InputStream in = this.getClass().getClassLoader().getResourceAsStream("web" + session.getUri());
