Question

有基于Jersey 2.23.2＆amp ;;的REST Web服务。 Guice 3.0。要使用Guice，必须调整hk2-guice bridge（我使用2.5.0-b07）。在我尝试使用Jersey Test Framework测试服务之前，一切正常。无法为测试配置hk2-guice网桥。

我的测试：

public class SomeTest extends JerseyTestNg.ContainerPerClassTest {

    @Override
    protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
        return new GrizzlyWebTestContainerFactory();
    }

    @Override
    protected Application configure() {
        return super.configure(); // cant't configure
    }

    @Test
    public void test() {
        Assert.assertEquals(1, 1);
    }
}

我无法在SomeTest.configure()中配置测试只返回new JerseyConfiguration()（见下文），因为JerseyConfiguration的构造函数需要ServiceLocator的对象。

即使可以返回类“JerseyConfiguration”类的对象 - 我也不确定我的测试是否可行，因为在web.xml文件中定义了一些过滤器和监听器。

如何在考虑所有过滤器，监听器和hk2-guice桥的情况下配置测试？

build.gradle的依赖关系部分：

def jerseyVersion = '2.23.2'
def hk2Version = '2.5.0-b07'
def giuceVersion = '3.0'

dependencies {
    compile "javax.servlet:javax.servlet-api:3.1.0"
    //jersey
    compile "org.glassfish.jersey.core:jersey-server:${jerseyVersion}"
    compile "org.glassfish.jersey.containers:jersey-container-servlet:${jerseyVersion}"
    //hk2
    compile "org.glassfish.hk2:guice-bridge:${hk2Version}"
    //guice
    compile "com.google.inject:guice:${giuceVersion}"
    compile "com.google.inject.extensions:guice-servlet:${giuceVersion}"
}

类JerseyGuiceServletContextListener：

public class JerseyGuiceServletContextListener extends GuiceServletContextListener {
    static Injector injector;

    @Override
    protected Injector getInjector() {
        injector = Guice.createInjector(new JerseyServletModuleConfig());
        return injector;
    }
}

类JerseyServletModuleConfig：

class JerseyServletModuleConfig extends ServletModule {
    @Override
    protected void configureServlets() {
        bind(HeyResource.class).in(Scopes.SINGLETON);
    }
}

Class JerseyConfiguration：

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(JerseyGuiceServletContextListener.injector);
    }
}

刚刚覆盖configureDeployment()＆amp;测试中修改了configure()方法

public class SomeTest extends JerseyTestNg.ContainerPerClassTest {

    @Override
    protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
        return new GrizzlyWebTestContainerFactory();
    }

@Override
    protected Application configure() {
        return new ResourceConfig()
                .packages("com.example.ws")
                .register(GensonCustomResolver.class);
    }

    @Override
    protected DeploymentContext configureDeployment() {
        Application application = configure();

        return ServletDeploymentContext.builder(application)
                .addListener(JerseyGuiceServletContextListener.class)
                .addFilter(GuiceFilter.class, "guiceFilter")
                .addFilter(ServletContainer.class, "jerseyFilter", new HashMap<String, String>(){{
                    put("javax.ws.rs.Application", JerseyConfiguration.class.getCanonicalName());
                }})
                .build();
    }

    @Test
    public void test() {
        Assert.assertEquals(1, 1);
    }
}

＆安培;添加web.xml以测试类路径。
