java - Jersey 测试框架和 HK2-Guice 桥

Question

有基于 Jersey 2.23.2 和 Guice 3.0 的 REST Web 服务。要使用Guice，需要调整hk2-guice bridge (我使用的是 2.5.0-b07)。一切正常，直到我尝试使用 Jersey Test Framework 测试服务。 。无法配置 hk2-guice 桥接器进行测试。

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 `JerseyConfiguration` 类的对象 - 我也不确定我的测试是否有效，因为 web.xml 文件中定义了一些过滤器和监听器。

如何配置考虑所有过滤器、监听器和hk2-guice桥的测试？

    static Injector injector;

         GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);
         GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);
         guiceBridge.bridgeGuiceInjector(JerseyGuiceServletContextListener.injector);
    }
}

刚刚覆盖了 configureDeployment() 并修改了测试中的 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);
    }
}

& 添加 web.xml 到测试类路径。
