查看已弃用类的JavaDocs：

Take a look into JavaDocs of deprecated classes:

* @deprecated as of 1.4 in favor of
 * {@link org.springframework.boot.test.context.SpringBootTest} with

 */
...
@Deprecated
public @interface WebIntegrationTest {

* @deprecated as of 1.4 in favor of {@link SpringBootTest} or direct use of
* {@link SpringBootContextLoader}.
*/
...
@Deprecated
public @interface SpringApplicationConfiguration {

 * @deprecated as of 1.4 in favor of
 * {@link org.springframework.boot.test.web.client.TestRestTemplate}
 */
@Deprecated
public class TestRestTemplate extends RestTemplate {
