泽西测试框架和HK2-吉塞桥 [英] Jersey Test Framework & HK2-Guice bridge

问题描述

存在基于泽西岛2.23.2&的REST Web服务. Guice 3.0.要使用Guice，必须调整 hk2-guice桥( m使用2.5.0-b07).一切正常，直到我尝试使用 Jersey测试框架.无法配置hk2-guice桥进行测试.

There are REST web service based on Jersey 2.23.2 & Guice 3.0. To use Guice it is necessary to adjust the hk2-guice bridge (I'm using 2.5.0-b07). Everything works fine until I have tried to test the service using Jersey Test Framework. Can't configure hk2-guice bridge for tests.

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，只是返回new JerseyConfiguration()(请参见下文)，因为JerseyConfiguration的构造函数期望ServiceLocator的对象.

I can't configure test in SomeTest.configure() just returning new JerseyConfiguration() (see below) because JerseyConfiguration's constructor expected ServiceLocator's object.

即使有可能返回"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侦听器.

Even if it were possible to return an object of class `JerseyConfiguration` - I'm not sure that my test would work because some filters and listener are defined in the web.xml file.

如何在考虑所有过滤器，侦听器和hk2-guice网桥的情况下配置测试?

JerseyGuiceServletContextListener类:

Class JerseyGuiceServletContextListener:

public class JerseyGuiceServletContextListener extends GuiceServletContextListener {
    static Injector injector;

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

JerseyServletModuleConfig类:

Class JerseyServletModuleConfig:

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

JerseyConfiguration类:

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);
    }
}

推荐答案

仅覆盖configureDeployment()&修改了configure()测试中的方法

just overrode configureDeployment() & modified configure() methods in test

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);
    }
}

&添加web.xml以测试类路径.

& add web.xml to test classpath.
