Spring MVC 3.0.0应用程序不会在Weblogic Server 11gR1上引导--ClassCastException

And*_*Law 4 java deployment spring spring-mvc weblogic11g

我有一个基于Spring MVC(3.0.0.RELEASE)的应用程序,我需要部署到Oracle Weblogic Server 11gR1.它在Spring TC Server上运行良好.当我部署应用程序WAR文件时(通过STS/Eclipse"服务器"视图或"自动部署"文件夹,或通过Web管理员手动),我得到以下异常:

在weblogic.xml中(修复了我无数早期的问题 - 类路径完全被搞砸了,我在Spring的"getBeanDefinitionDefaults(...)"中遇到了"NoSuchMethodError"问题,这个问题捆绑在我的WAR的WEB-INF/lib目录中).

调查显示,javax.xml.parsers.DocumentBuilderFactory来自xml-apis-1.0.b2.jar是由maven从commons-digester,dom4j和jdom引入的.简而言之,我需要它来运行我的Spring App.

我已经检查过了(并仔细检查过)并且我没有将我的战争捆绑在weblogic类中,所以我不是自己动手拍摄自己.

我也在java.net论坛上看过这篇文章:http://forums.java.net/jive/thread.jspa？messageID = 216363 - Log4J解决方法不起作用(我认为是因为问题的根源是不是Log4J)和oracle.com上的这个bug修复说明(搜索"CR172469")http://download-llnw.oracle.com/docs/cd/E13222_01/wls/docs81/notes/resolved_sp03.html 这似乎什么也不做.

我不明白的是,我告诉Weblogic更喜欢我的WEB-INF/lib中的jar,我需要的jar就在那里,错误来自Spring,而不是Weblogic(即我不是强迫服务器本身使用它无法处理的jar.)

因为我不确定它的相关性,所以我暂时没有将更多的Spring配置添加到这个问题中.如果这会有所帮助,请告诉我,我会添加它.

希望有人能提供帮助.

您的应用程序几乎肯定不会包含任何javax.*类本身 - 这些通常由应用程序服务器处理.如果你这样做,你最终会ClassCastExceptions像这样.

你需要阻止maven拖入类似的东西xml-apis-1.0.b2.jar,它不属于你的应用程序.

如果你解决了这个问题,那么你就不必担心特定于weblogic的类加载器设置了.

  • 谢谢@skaffman这很有效.选择性地使用"mvn dependency:tree"帮助我掌握了从哪里来的东西.然后我使用<dependency> <exclusions> <exclusion>和<scope>标签来获取我在WAR文件中想要的东西. (2认同)
