클래스 JerseyGuiceServletContextListener :

build.gradle에서

종속성 섹션 10

클래스 JerseyServletModuleConfig :

package com.example.core; 

import com.google.inject.Scopes; 
import com.google.inject.servlet.ServletModule; 
import com.example.ws.HeyResource; 
import org.glassfish.jersey.servlet.ServletContainer; 

import java.util.Map; 
import java.util.TreeMap; 

class JerseyServletModuleConfig extends ServletModule { 
    @Override 
    protected void configureServlets() { 
     Map<String, String> servletContainerParams = new TreeMap<>(); 
     servletContainerParams.put("javax.ws.rs.Application", JerseyConfiguration.class.getCanonicalName()); 
     bind(ServletContainer.class).in(Scopes.SINGLETON); 
     filter("/*").through(ServletContainer.class, servletContainerParams); 
     bind(HeyResource.class).in(Scopes.SINGLETON); 
    } 
} 

클래스 JerseyConfiguration는 : 버전 2.22.1 뉴저지 모든 것을

package com.example.core; 

import com.google.inject.Injector; 
import org.glassfish.hk2.api.ServiceLocator; 
import org.glassfish.jersey.server.ResourceConfig; 
import org.jvnet.hk2.guice.bridge.api.GuiceBridge; 
import org.jvnet.hk2.guice.bridge.api.GuiceIntoHK2Bridge; 

import javax.inject.Inject; 
import javax.servlet.ServletContext; 

class JerseyConfiguration extends ResourceConfig { 
    @Inject 
    public JerseyConfiguration(ServiceLocator serviceLocator, ServletContext servletContext) { 
     packages("com.example.ws"); 
     GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator); 
     GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class); 
     guiceBridge.bridgeGuiceInjector((Injector) servletContext.getAttribute(Injector.class.getName())); 
    } 
} 

완벽하게 작동합니다.

나는 그것이 guice 다리 버전에서 다룰 수있는 문제를 생각했다. 필자는 2.4.0-b31 버전을 org.glassfish.jersey.core : jersey-server의 다양한 hk2 종속성에 사용되는 2.4.0-b34 버전으로 대체했습니다. - 도움이되지 않았습니다. 클래스 FilterUrlMappingsProviderImpl에

설명 클래스 FilterUrlMappingsProviderImpl 위의 링크는이 FilterRegistration 클래스 개체를 가져 불가능하다는 것을 분명해진다.

어떤 문제가있을 수 있습니까? 그녀의 결정에 대해 당신은 무엇을 조언 할 수 있습니까? 감사합니다. .
