使用JUnit测试Apache CXF JAX-WS服务

Question

我在组合Apache CXF 2.7.6、Spring 3.1.4和JUnit 4.8时遇到了一个问题。我尝试了多种场景，但总是以以下异常结束：

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'client': FactoryBean threw exception on object creation; nested exception is java.lang.NoSuchMethodError: org.apache.cxf.common.classloader.ClassLoaderUtils.loadClass(Ljava/lang/String;Ljava/lang/Class;Ljava/lang/Class;)Ljava/lang/Class;

我的test-application-context.xml非常简单：

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<jaxws:client id="client" serviceClass="sk.package.definitions.some.SomeService" address="http://localhost:9080/some/SomeService" />

我的测试用例是这样的：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/test-application-context.xml" })
public class SomeServiceTestCase {
@Autowired
ApplicationContext context;
private SomeService someService;

@Test
public void testGetOffer() {
    someService = (SomeService) context.getBean("client");
  }
}

我使用这三个CXF依赖项：

<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-api</artifactId>
<version>2.7.6</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>2.7.6</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>2.7.6</version>
<scope>compile</scope>
</dependency>

谢谢你的建议，

您有不同版本的CXF工件的混合吗？

看看这个：https://issues.apache.org/jira/browse/CXF-5132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13709765#comment-13709765

我认为异常是由cxf公共实用程序引起的。cxf-common实用程序中有一个类org.apache.cxf.common.classloader.ClassLoaderUtils，它与cxf-api中的类org.apache.cxf.common.classloader.ClassLoaderUtils冲突

尝试删除cxf公共实用程序的依赖项，看看它是否能在
