我正在创建一个基于 Jersey + Spring + Hibernate 的 REST API。部署后一切正常。
我尝试使用 RestAssured 添加一些集成测试,我想从嵌入式 Jetty(强制性规范)开始,但它总是会出现此错误(有关详细堆栈跟踪,请参见下文):
20-04-2013 | 19:14:43 | WARN | (Slf4jLog.java:76) | failed jersey-servlet: java.lang.IncompatibleClassChangeError: Implementing class
20-04-2013 | 19:14:43 | WARN | (Slf4jLog.java:76) | failed org.mortbay.jetty.webapp.WebAppContext@192ffd75{/test-core,src/main/webapp}: java.lang.IncompatibleClassChangeError: Implementing class
20-04-2013 | 19:14:43 | ERROR | (Slf4jLog.java:87) | Error starting handlers
正如错误所说,这可能与我的 SpringServlet 有关,但是我似乎无法解决这个问题。

最后是将启动我的码头服务器的类(在 JUnit 测试中扩展的 WithJetty 类)的方法:
@BeforeClass
public static void startJetty() throws Exception {
server = new Server(8070);
WebAppContext context = new WebAppContext();
context.setDescriptor("src/main/webapp/WEB-INF/web.xml");
context.setWar("src/main/webapp");
context.setParentLoaderPriority(true);
context.setContextPath("/testing-core");
server.setHandler(context);
server.setStopAtShutdown(true);
server.start();
}
实际的测试用例非常基本:
public class UserResourceTest extends WithJetty {
@Test
public void test() throws Exception {
Assert.assertEquals(200, given().log().all().get(RSConstants.PATH_UNSECURED + "/test").getStatusCode());
}
}

我已经在互联网和 stackoverflow 上搜索了可能的解决方案,但我发现所有这些都与 GAE 有关(我没有使用)
非常感谢您的帮助!
