我的JerseyTest课程有一个奇怪的问题。
当执行我的测试代码并在org.glassfish.jersey.message.internal.ReaderInterceptorExecutor的第203行放置断点时,我看到我的读者不在读者工作者中。但是,如下所示,我在ResourceConfig中注册了此MessageBodyReader。
以下提供所有相关代码。
@Provider
@Produces({V1_JSON})
@Consumes({V1_JSON})
public class JsonMessageBodyHandlerV1
implements
MessageBodyWriter<Object>,
MessageBodyReader<Object> {
...
}
是的,isReadable
会返回 true 。
调试时,我发现代码会点击writeTo
,但不会 readFrom
。
public class TestLocationResource extends JerseyTest {
public static class LocationResourceHK2Binder extends AbstractBinder {
@Override
protected void configure() {
// Singleton bindings.
bindAsContract(LocationDao.class).in(Singleton.class);
// Singleton instance bindings.
bind(new FakeLocationDao()).to(LocationDao.class);
}
}
@Test
public void basicTest() {
LocationListV1 actualResponse = /**/
/**/target(LocationResourceV1.PathFields.PATH_ROOT)
/* */.path(LocationResourceV1.PathFields.SUBPATH_LIST)
/* */.request(V1_JSON)
/* */.header(HEADER_API_KEY, "abcdefg")
/* */.get(LocationListV1.class);
assertEquals(10, actualResponse.getLocations().size());
}
@Override
protected Application configure() {
enable(TestProperties.LOG_TRAFFIC);
enable(TestProperties.DUMP_ENTITY);
ResourceConfig rc = new ResourceConfig();
rc.registerClasses(LocationResourceV1.class, JsonMessageBodyHandlerV1.class);
rc.register(new LocationResourceHK2Binder());
return rc;
}
}
(从this example拉出来。)
public class LocationResourceV1 implements ILocationResourceV1 {
...
@Inject
private LocationDao daoLoc;
private final LocationTranslator translator = new LocationTranslator();
@Override
public LocationListV1 listV1(String apiKey) {
return translator.translate(daoLoc.query(LocationFilters.SELECT_ALL));
}
...
@VisibleForTesting
public void setLocationDao(LocationDao dao) {
this.daoLoc = dao;
}
}
(请注意,@ GET等Web服务注释位于界面中。)

任何人都知道我做错了什么?
答案 0 :(得分:3)
第一个堆栈跟踪来自您的客户端,因为您没有在那里注册您的消息体提供者(因此无法找到它)。 JerseyTest#configure方法应该用于仅配置服务器端。还有另一种名为JerseyTest#configureClient的方法,旨在用于客户端。如果要使用自定义提供程序,则需要覆盖这两种方法。
第二个堆栈跟踪来自您的LocationResourceHK2Binder
。由
bindAsContract(LocationDao.class).in(Singleton.class);
你告诉HK2 LocationDao
类应该被实例化为单例,而HK2会将它注入LocationDao
类型。您可能希望更改活页夹以使用以下内容:
bind(new FakeLocationDao()).to(LocationDao.class);
