我试图在Tomcat 7.0.29中部署一个war。我有以下日志堆栈:

(提交了许多堆栈帧…)
有人面临同样的问题吗?
这在Tomcat中作为问题#53871向上游报告。问题似乎出在注释扫描上,Tomcat 7.0.38包含了一条更清晰的错误消息。
来自错误报告:
由于依赖关系管理问题,我部署了一个WAR文件,其中包含两个JAR文件,它们包含库的不同版本,其中版本1包含从B继承的类a,另一个版本2包含从a继承的类B。类的加载顺序使得A和B循环地相互继承,这导致populateSCIsForCacheEntry中的堆栈溢出,因为它在继承树中没有检测到循环。
这正是我案例中的问题:旧版本的dom4j
捆绑了不兼容的jaxen
版本。7.0.38中的新错误诊断准确地显示了哪些类形成了一个循环,我通过升级这些依赖关系来修复它。
我在Tomcat 7.0中也遇到了这个问题。29和Tomcat 7.0。30。但是,有了Tomcat 7.028,一切都很好,所以我怀疑这是最近引入的Tomcat问题。
在7.0.29和7.0.30中,启动Tomcat并部署war文件时遇到错误:

对我来说,当我将应用程序上下文设置为与.pom文件中的Maven atrifactId相同的名称时,IntelliJ Idea中再现了这种行为。例如,我的artifactId是"test",然后我将Application Context(编辑配置->Tomcat服务器->部署,选择分解的工件)设置为"/test"。一旦我更改了应用程序上下文,一切都正常了。
我也遇到了同样的问题。我认为这是由Tomcat 7引起的,所以当我更改为Tomcat6.0.35时,问题像一个符咒一样自行解决了。
使用Tomcat的较低版本。您使用的Tomcat版本存在问题。
解决方法:我更改了WAR的名称(pom.xml中没有finalName,并更改了工件版本),它成功了。。。。为什么?我现在才知道!
真正的解决方案?无疑是一个新的Tomcat版本。
