java – WireMock使用NoSuchMethodError HttpServletResponse.getHeader失败
作者：互联网
我正在尝试在我的JUnit测试中使用WireMock来模拟对外部API的调用.
public class ExampleWiremockTest {
@Rule
public WireMockRule wireMockRule = new WireMockRule(9999);
@Before
public void setUp() {
stubFor(get(urlEqualTo("/bin/sillyServlet"))
.willReturn(aResponse()
.withStatus(200)
.withBody("Hello WireMock!")
)
);
}
@Test
public void testNothing() throws URISyntaxException, IOException {
URI uri = new URIBuilder().setScheme("http")
.setHost("localhost")
.setPort(9999)
.setPath("/bin/sillyServlet")
.build();
HttpGet httpGet = new HttpGet(uri);
CloseableHttpClient httpClient = HttpClients.createDefault();
CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity entity = response.getEntity();
String body = EntityUtils.toString(entity);
assertThat(body, is("Hello WireMock!"));
}
}
代码编译但是当我运行我的测试时,WireMock会抛出一个似乎是由底层Servlet API版本中的不一致引起的HTTP 500.

我的classpath中有其他库依赖不同版本的Jetty,我想这是问题的原因.
WireMock使用Jetty 9.2.13,我对Cobertura也有传递依赖,它依赖于6.1.14
我原本试图使用以下依赖项：
<dependency>
<groupId>com.github.tomakehurst</groupId>
<artifactId>wiremock</artifactId>
<version>2.6.0</version>
</dependency>
我切换到独立的Jar版本,希望它能帮助我避免冲突,但结果完全一样.
<dependency>
<groupId>com.github.tomakehurst</groupId>
<artifactId>wiremock-standalone</artifactId>
<version>2.6.0</version>
</dependency>
解决方法:
检查你的servlet-api版本,你可能正在使用旧版本.
这两种方法都是在Servlet 3.0中添加的
> HttpServletResponse.getHeader(String name)
> HttpServletRequest.isAsyncStarted()
您可能在类路径中有Servlet 2.5(或Servlet 2.4)jar.
