Grizzly和Jersey独立罐子

Question

我正在尝试使用Maven shade插件将Grizzly打包为Jersey作为单个jar.但我总是得到消息No container provider supports the type class org.glassfish.grizzly.http.server.HttpHandler

代码在Eclipse中运行良好,但在打包的jar中不行:

public class Main {

private static URI getBaseURI() {
    return UriBuilder.fromUri("http://localhost/").port(9998).build();
}

public static final URI BASE_URI = getBaseURI();

protected static HttpServer startServer() throws IOException {
    System.out.println("Starting grizzly...");
    ResourceConfig rc = new PackagesResourceConfig("share.test");
    rc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
    return GrizzlyServerFactory.createHttpServer(BASE_URI, rc);
}

public static void main(String[] args) throws IOException {
    HttpServer httpServer = startServer();
    System.in.read();
    httpServer.stop();
}    
}

这是完整的例外

我正在使用maven构建jar包

<build>
 <plugins>
  <plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-shade-plugin</artifactId>
   <version>1.5</version>
   <configuration>
   <transformers>
   <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
     <manifestEntries>
      <Main-Class>share.test.Main</Main-Class>
      <Build-Number>1</Build-Number>
     </manifestEntries>
    </transformer>
  </transformers>
 </configuration>
<executions>
 <execution>
  <phase>package</phase>
   <goals>
    <goal>shade</goal>
   </goals>
 </execution>
</executions>
</plugin>
</plugins>
</build>

我是否需要更改阴影插件以包含其他内容？

Answer 1

错误看起来插件没有正确合并来自不同罐子的META-INF /服务记录 - 如果在几个罐子的META-INF/services目录中有多个具有相同名称的文件,则需要合并,而不是替换一个由另一个.检查是否是这种情况.
