Как мой тест JUnit может найти мой источник данных Tomcat?

Question

Я пытаюсь проверить мои REST Services. Я использую JerseyTest Jersey2 и предоставленную инфраструктуру JDK HttpServer. Мне нужны тесты для доступа к источнику данных, который определен в META-INF/context.xml. Службы развернуты на Tomcat.

Как добавить ContextConfig к ResourceConfig, чтобы он работал?

Это код настройки, который в данный момент не работает. Кажется, что контекст не регистрируется.

@Override
protected Application configure() {
    ResourceConfig rc = new ResourceConfig(OfficeSpaceService.class);
    rc.property("contextConfigLocation", "src/main/webapp/META-INF/context.xml");

    return rc;
}

И это тестовый код:

@Test
public void getSpacesTest() {
    Response response = 
        target("v1/space/")
        .request()
        .get(Response.class);

    int status        = response.getStatus();
    MediaType mt      = response.getMediaType();
    String spacesJson = response.readEntity(String.class);

    //Assertions here.
}

И это исключение, когда служба пытается найти источник данных:

Есть один из способов:

ResourceConfig rc = new ResourceConfig(OfficeSpaceService.class);
rc.property("contextConfig",new ClassPathXmlApplicationContext(
new String[]{"src/main/webapp/META-INF/context.xml"},
ContextLoader.getCurrentWebApplicationContext()));
