泽西岛给出运行时错误java.lang.NoClassDefFoundError:org/glassfish/jersey/server/ResourceConfig [英] Jersey gives runtime error java.lang.NoClassDefFoundError: org/glassfish/jersey/server/ResourceConfig

问题描述

我将球衣服务定义为:

private static HttpServer createHttpServer() throws IOException {
    final ResourceConfig resourceConfig = new ResourceConfig(Api.class);

    return JdkHttpServerFactory.createHttpServer(URI, resourceConfig);

}

这可以编译.但是，当我尝试运行它时，它会抛出java.lang.NoClassDefFoundError:

This compiles fine. But when I try to run it it throws java.lang.NoClassDefFoundError:

        Exception in thread "main" java.lang.NoClassDefFoundError: org/glassfish/jersey/server/ResourceConfig
        at EmbeddedHTTPServer.createHttpServer(Unknown Source)
        at EmbeddedHTTPServer.main(Unknown Source)
    Caused by: java.lang.ClassNotFoundException: org.glassfish.jersey.server.ResourceConfig
        at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

这些是库:

$ ls lib
commons-collections-3.2.1.jar  jsoup-1.8.3.jar
commons-dbcp-1.4.jar           logback-classic-1.1.3.jar

jersey-container-jdk-http.jar  rome-utils-1.5.1.jar
jersey-server.jar              slf4j-api-1.7.12.jar
json.jar

Env:

1. Ubuntu
2. Oracle JDK 1.8
3. JAX-RS 2

有什么主意吗?

谢谢.

推荐答案

似乎Jersey仅在lib文件夹中的jar才能正确编译，而在运行时则需要ext文件夹中的jar.

It appears Jersey compiles properly with only jars in lib folder but at runtime jars in ext folder are required.

从JAX-RI捆绑包中将jar添加到ext文件夹后，问题解决了.

After adding jars in ext folder from the JAX-RI bundle issue resolved.
