Jersey2，Hk2dependency injection（自动）给出AbstractMethodError：org.jvnet.hk2.internal.DynamicConfigurationImpl.addIdempotentFilter

坚持这个问题一段时间。 我正在尝试集成Tomcat 9，JDK 10，Jersey 2.23，HK2（用于DI）以及自动dependency injection。 我已经按照本教程 ，但得到以下错误，我搜索了很多，但没有找到任何东西。

我已经使用依赖来生成“META-INF / hk2-locator / default”，它正在生成。

依赖

 org.glassfish.hk2 hk2-metadata-generator 2.4.0

自动DI代码

 import java.io.IOException; import javax.ws.rs.core.Feature; import javax.ws.rs.core.FeatureContext; import org.glassfish.hk2.api.DynamicConfigurationService; import org.glassfish.hk2.api.MultiException; import org.glassfish.hk2.api.Populator; import org.glassfish.hk2.api.ServiceLocator; import org.glassfish.hk2.utilities.ClasspathDescriptorFileFinder; import org.glassfish.hk2.utilities.DuplicatePostProcessor; import org.glassfish.jersey.ServiceLocatorProvider; //This class will cause the HK2 framework to scan your classpath for inhabitants files that are created using the hk2-inhabitant-generator. public class MyDiscoverableFeature implements Feature { @Override public boolean configure(FeatureContext context) { ServiceLocator locator = ServiceLocatorProvider.getServiceLocator(context); DynamicConfigurationService dcs = locator.getService(DynamicConfigurationService.class); Populator populator = dcs.getPopulator(); try { populator.populate(new ClasspathDescriptorFileFinder(this.getClass().getClassLoader()), new DuplicatePostProcessor()); } catch (IOException | MultiException ex) { System.out.println("exception occurred " + ex); } return true; } } public class ResourceConfiguration extends ResourceConfig { public ResourceConfiguration() { // register(ControllerTest.class); // register(new MyBinder()); this.packages(true, "com.walmart.services.*"); // for auto scan register(MyDiscoverableFeature.class); } } 

我有一个用org.jvnet.hk2.annotations.Contract（@Contract）注释的接口“IUserService”，带有用org.jvnet.hk2.annotations.Service（@Service）注释的implmentation“UserServiceImpl”

我有一个控制器类：

 @Path("/sayHello") public class ControllerTest { @Inject private IUserService service; @Inject private ServicesTest service2; @GET @Path("/{name}") @Produces(MediaType.TEXT_PLAIN) public String method(@PathParam("name") String msg) { return service.method() + msg; } @GET @Path("/v2/{name}") @Produces(MediaType.TEXT_PLAIN) public String method2(@PathParam("name") String msg) { return service.method() + msg; } } 

以及下面的依赖项

    javax javaee-api 8.0      org.glassfish.jersey.core jersey-server ${jersey2.version}   org.glassfish.hk2 hk2-utils   org.glassfish.hk2 hk2-api   org.glassfish.hk2.external javax.inject      org.glassfish.jersey.core jersey-common ${jersey2.version}   org.glassfish.hk2 hk2-utils   org.glassfish.hk2 hk2-api   org.glassfish.hk2.external javax.inject     org.glassfish.jersey.containers jersey-container-servlet ${jersey2.version}   org.glassfish.hk2.external javax.inject       org.glassfish.jersey.inject jersey-hk2 2.27    org.glassfish.jersey.media jersey-media-json-jackson ${jersey2.version}     org.glassfish.hk2 hk2-metadata-generator 2.4.0   

更新

我删除依赖冲突后立即修复上述问题。

但是现在，我的其余资源根本没有被检测到，所以我的rest资源上有404错误。

但是，如果我在“ResourceConfiguration”//注册（ControllerTest.class）中取消注释这一行; 然后它开始出现。

但我不想为每个singelrest资源做这个（不实用）请帮助解决这个问题

@PaulSamsotha; 如你所提到的那样改变;

 this.packages(true, "com.walmart.services.*"); 

至

 this.packages(true, "com.walmart.services"); 

在服务器启动时给出以下错误;

这是完整的错误;

不知道它的原因但是一旦我删除“。*”，在服务器启动时我得到以下错误。

此外，我发现上面的行没有任何意义，即使我完全删除它与控制器的寄存器一切正常。
