CXF失败，单元测试中出现不兼容ClassChangeError异常



我有一个使用Spring-3.2.X和cxf-2.7.5的应用程序

我正在将cxf导入我春季的应用程序上下文中，如下所示：

<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:cxf.xml" />

然而，当我运行测试时，我会出现以下异常：

阅读java.lang.IncompatibleClassChangeError的原因是什么？它看起来像IncompatibleClassChangeError-意味着我的类路径上可能有冲突的库版本。我无法从堆栈跟踪中判断出哪个类/库正在被复制。

如果你还在这里，谢谢你的阅读
我做错了什么
为什么CXF/Spring不能启动，我该如何修复它？

更新：
运行调试器后，出现问题的类似乎是：org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl
，它位于cxf-rt-ws-policy-2.7.5
据我所知，这是那个罐子的唯一位置，它只包含一次。

JHades更新
当我最初运行报告时，Log4J和Log4J的额外内容重叠JavaMail-1.5和geronimo-JavaMail_1.4_spec。我已经解决了这些用法。

报告结果：

>>>> Jar overlap report: 

Total number of classes with more than one version: 0

Jhades和mvn dependency:tree -Ddetail=true都表明cxf-rt-ws-policy与其他cxf-jar版本一样，是2.7.5。

所以我发现我的IDE intellij dea把我的构建搞砸了
我想既然我配置了maven，它就只是在引擎盖下运行纯maven
在我的IDE中，我为Axis2-1.6.0配置了一个已安装的目录，以便在我的maven依赖项之前使用。Axis-2是我的应用程序的旧版本遗留下来的，它包含许多依赖项的副本，包括名为Neethi的东西，我看到它在CXF中列出了其他地方作为此错误的潜在来源。

似乎正在加载的类org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl的版本无效。

您可以使用这个命令(来自JHades，我制作的一个工具)检查WAR，看看是否有任何重复的类，请参阅这里的重复类报告：

java -jar jhades-standalone-report.jar path/to/war/webapp.war

报告应该给出这样的内容：

>>>> Jar overlap report:
poi-3.5-FINAL-20090928.jar overlaps with poi-3.7-20101029.jar - total overlapping classes: 990
xercesImpl-2.7.0.jar overlaps with xercesImpl-2.9.1.jar - total overlapping classes: 867
xalan-2.6.0.jar overlaps with xalan-2.7.1.jar - total overlapping classes: 711
bcel-5.2.jar overlaps with xalan-2.7.1.jar - total overlapping classes: 361
xml-apis-2.9.1.jar overlaps with xml-apis.jar - total overlapping classes: 301
jasperreports-applet-3.7.1.jar overlaps with jasperreports-javaflow-3.7.1.jar - total overlapping classes: 254
jasperreports-3.7.1.jar overlaps with jasperreports-applet-3.7.1.jar - total overlapping classes: 254
...
Total number of classes with more than one version: 6169

还可以查询类的所有版本和当前使用的版本的类路径：

System.out.println("All versions of AssertionBuilderRegistryImpl:" + getClass().getClassLoader().getResources("org/apache/cxf/ws/policy/AssertionBuilderRegistryImpl.class"));
System.out.println("Currently used version of AssertionBuilderRegistryImpl:" + getClass().getClassLoader().getResource("org/apache/cxf/ws/policy/AssertionBuilderRegistryImpl.class"));

有两种可能性：要么存在多个版本，要么只有一个是正确的。在这种情况下，排除maven中版本错误的jar。

如果只存在一个版本，那么它就是错误的版本，请使用mvn dependency:tree -Ddetail=true查找包含它的原因，并更新pom以加载正确的版本。
