JAX-RS 2.0 - How to get entity from Response object
提问by Bartek Andrzejczak
I'm using JAX-RS 2.0 with Dropwizard 0.8.0-rc1 and I really can't figure out how to pull my entity from javax.ws.rs.core.Responseobject. response.getEntity()gives me ByteArrayOutputStream. I can create two requests - one that gives me headers and links and the other that gives me my response entity, but it seems like a stupid, wasteful and unclear thing to do. Is there a way for getting entity from response object?
我正在将 JAX-RS 2.0 与 Dropwizard 0.8.0-rc1 一起使用，但我真的不知道如何从javax.ws.rs.core.Response对象中拉出我的实体。response.getEntity()给我ByteArrayOutputStream。我可以创建两个请求——一个给我标题和链接，另一个给我我的响应实体，但这似乎是一件愚蠢、浪费和不清楚的事情。有没有办法从响应对象中获取实体？
My current test code is as follows:
我目前的测试代码如下：
public class GroupsResourceTest {
public static String CONFIGURATION_FILE = "src/test/resources/test-conf.yml";
@ClassRule
public final static DropwizardAppRule<BpmConsoleConfiguration> RULE =
new DropwizardAppRule<>(BpmConsoleApplication.class, CONFIGURATION_FILE);
static Client client;
@BeforeClass
public static void initClient(){
client = new JerseyClientBuilder(RULE.getEnvironment()).build("client");
client.register(HttpAuthenticationFeature.basic(User.ADMIN.login, User.ADMIN.password));
}
@Test
public void shouldGetGroups() {
//when
WebTarget resource = target("/groups");
List<String> groups = resource.request().get(new GenericType<>(List.class)); //first request
Response response = resource.request().get(); //second request
Link self = response.getLink("self");
//then
assertThat(self.getUri().getPath()).isEqualTo("/groups");
assertThat(groups).contains(User.ADMIN.login);
}
public WebTarget target(String path){
String url = String.format("http://localhost:%d%s", RULE.getLocalPort(), path);
return client.target(url);
}
}

You can use:
您可以使用：
public abstract <T> T readEntity(Class<T> entityType)- Read the message entity input stream as an instance of specified Java type using a MessageBodyReader that supports mapping the message entity stream onto the requested type.
public abstract <T> T readEntity(Class<T> entityType)- 使用支持将消息实体流映射到请求类型的 MessageBodyReader 将消息实体输入流作为指定 Java 类型的实例读取。
