我有一个控制器
@RestController
public class NameController {
@Autowired
private NameService nameService;
@GetMapping("/name")
public Mono<UploadParamsDto> getName(ServerHttpRequest request) {
return nameService.getNameByHost(request.getRemoteAddress().getHostName());
}
}
我有一个测试方法:
@ExtendWith(SpringExtension.class)
@WebFluxTest(NameControllerTest.class)
@ActiveProfiles("test")
class NameControllerTest {
@Autowired
private WebTestClient webClient;
@Test
void nameTest() {
webClient.get().uri("/name")
.accept(MediaType.APPLICATION_JSON)
.exchange()
.expectStatus()
.isOk();
}
}
当我运行测试以检查我的getName方法时,我得到了NPE,因为 request.getRemoteAddress()返回null,请告诉我如何模拟ServerHttpRequest吗? (我知道有MockServerHttpRequest,但我无法对其进行管理)
我的目的是使request.getRemoteAddress()。getHostName()返回模拟值。

感谢大家。 可通过以下方式工作:
@ExtendWith(SpringExtension.class)
@WebFluxTest(NameControllerTest.class)
@ActiveProfiles("test")
class NameControllerTest {
@Autowired
private ApplicationContext context;
@Test
void nameTest() {
WebTestClient webClient = WebTestClient
.bindToApplicationContext(context)
.webFilter(new SetRemoteAddressWebFilter("127.0.0.1"))
.configureClient()
.build();
webClient.get().uri("/name")
.accept(MediaType.APPLICATION_JSON)
.exchange()
.expectStatus()
.isOk();
}
}
其中SetRemoteAddressWebFilter是WebFilter:
public class SetRemoteAddressWebFilter implements WebFilter {
private String host;
public SetRemoteAddressWebFilter(String host) {
this.host = host;
}
@Override
public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
return chain.filter(decorate(exchange));
}
private ServerWebExchange decorate(ServerWebExchange exchange) {
final ServerHttpRequest decorated = new ServerHttpRequestDecorator(exchange.getRequest()) {
@Override
public InetSocketAddress getRemoteAddress() {
return new InetSocketAddress(host, 80);
}
};
return new ServerWebExchangeDecorator(exchange) {
@Override
public ServerHttpRequest getRequest() {
return decorated;
}
};
}
}

使用@WebFluxTest
运行测试并不涉及真正的服务器,您已经知道了。
但是获得NullPointerException
的感觉仍然不正确-您可以在https://jira.spring.io上对此提出问题吗?我认为您不必解决此问题,但是Spring Framework可能应该提供一些基础结构来“模拟”该信息。
