无法调用请求(Rest调用)
无法调用请求(Rest调用)
提问于 2015-10-13 05:16:44
我有rest服务(PUT)，我打算对它进行单元测试。我使用RestEasy进行Rest调用。
这是我的资源：
@Path("/my_person")
public class MyResource {
private MyDAO myDao;
@Inject
public MyResource(MyDao myDao) {
this.myDao = myDao;
}
@PUT
@Timed
@Path("purchase_number/{purchaseNumber}/amount/{amount}/number_of_items")
@Produces(MediaType.APPLICATION_JSON)
public Response getItems(@PathParam("purchaseNumber") String purchaseNumber,
@PathParam("amount") String amount) {
return Response.ok(String.format("{\"items\": %d}", myDao.getItems(purchaseNumber, amount))).build();
}
}myDao.getItems返回一个整数。
我的Test类如下：
@RunWith(MockitoJUnitRunner.class)
public class MyResourceTest {
@Mock
private MyDao myDao;
@InjectMock
private MyResource myResource;
private TJWSEmbeddedJaxrsServer server;
private ResteasyClient resteasyClient;
@Before
public void startServer() throws IOException {
resteasyClient = new ResteasyClientBuilder().build();
server = new TJWSEmbeddedJaxrsServer();
server.setPort(PORT);
server.setBindAddress("localhost");
server.getDeployment().getResources().add(myResource);
server.start();
}
@After
public void stopServer() {
if (server != null) {
server.stop();
server = null;
}
}
@Test
public void testWhenValidInputGiven() {
String purchaseNumber = "A57697DF";
String amount = "340";
when(myDao.getItems(purchaseNumber, amount)).thenReturn(10);
Response response = resteasyClient.target("http://localhost:9980/my_person/purchase_number/{purchaseNumber}/amount/{amount}/number_of_items").request().buildPut(Entity.entity("{}", MediaType.APPLICATION_JSON))).invoke();
String text = response.getEntity().toString();
assertEquals(200, resp.getStatus());
assertEquals("{\"items\": 10}", text);
}
}我在String text = response.getEntity().toString()得到以下错误，因为实体对象为空。那么这是否意味着它根本没有创建请求呢？

您是否尝试过将/放在方法路径@Path("/purchase_number/{purchaseNumber}/amount/{amount}/number_of_items")的前面
我认为框架误解了你的路径和期望的my_personpurchase_number/。检查你的响应状态码，看看是否真的得到了200或404。

这个问题的解决方案是我使用
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>而不是
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>jaxrs-api</artifactId>
<version>3.0.10.Final</version>
</dependency>两者都有javax.ws.rs.core.Response类。
