如何模拟restTemplate getForObject

Question

package rest;

@PropertySource("classpath:application.properties")
@Service
public class RestClient {

    private String user;
    // from application properties
    private String password;
    private RestTemplate restTemplate;

    public Client getClient(final short cd) {

        restTemplate.getInterceptors().add(new BasicAuthenticationInterceptor(user, password));

        Client client = null;

        try {
            client = restTemplate.getForObject("http://localhost:8080/clients/findClient?cd={cd}",
                    Client.class, cd);
        } catch (RestClientException e) {

            println(e);
        }

        return client;
    }

    public RestTemplate getRestTemplate() {
        return restTemplate;
    }

    public void setRestTemplate(final RestTemplate restTemplate) {
        this.restTemplate = restTemplate;
    }
}

package test;
@PropertySource("classpath:application.properties")
@RunWith(MockitoJUnitRunner.class)
public class BatchRestClientTest {


    @Mock
    private RestTemplate restTemplate;

    @InjectMocks
    private RestClient restClient;

    private MockRestServiceServer mockServer;

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void getCraProcessTest() {
        Client client=new Client();
        client.setId((long) 1);
        client.setCd((short) 2);
        client.setName("aaa");

        Mockito
            .when(restTemplate.getForObject("http://localhost:8080/clients/findClient?cd={cd},
                    Client.class, 2))
            .thenReturn(client);

        Client client2= restClient.getClient((short)2);
        assertEquals(client, client2);
    }

    public RestTemplate getRestTemplate() {
        return restTemplate;
    }

    public void setRestTemplate(RestTemplate restTemplate) {
        this.restTemplate = restTemplate;
    }

    public RestClient getRestClient() {
        return restClient;
    }

    public void setRestClient(RestClient restClient) {
        this.restClient = restClient;
    }
}

它返回null，而不是预期的客户端，对象类的resttemplate工作正常。我只想写测试。我是漏掉了什么还是做错了测试？谢谢你的指导。

改为使用以下内容：

Mockito.when(restTemplate.getForObject(
    "http://localhost:8080/clients/findClient?cd={id}",
    Client.class,
    new Object[] {(short)2})
).thenReturn(client);

第三个参数是varargs。因此，在测试中需要包装成对象[]，否则Mockito无法匹配它。请注意，这将在您的实现中自动发生。
