部署到Weblogic 11g的Spring Boot App无法启动

Question

我在将一个Spring Boot应用程序部署到Weblogic 10.3.3服务器时遇到了一些问题.我拼命地交叉手指,希望以前有人见过这个问题.我使用Weblogic的管理控制台来执行部署(这看起来很顺利),但是当我尝试启动应用程序时,我从Weblogic收到错误:

使用spring-boot-legacy和web.xml将应用程序部署为WAR文件.它在Tomcat 6/7/8上运行良好.这是我的相关配置文件:

web.xml中

weblogic.xml中

<wls:weblogic-web-app

跟踪堆栈跟踪,看起来Spring Boot的BeanDefinitionLoader类尝试加载源类(在我的情况下,只是com.example.Application),但是因为它没有将它看作类,资源或包而失败.在这里查看BeanDefinitionLoader类:BeanDefinitionLoader.java(第187行),看来我的Application类应该作为Class加载.就像我提到的,它在Tomcat中运行得很好,而不是在Weblogic中.

是否存在一些我缺少的Weblogic特定内容？它可能是文件编码问题吗？我错过了我的web.xml中的内容吗？

谢谢你的时间!

更新#1

在谷歌和StackOverflow用尽事情之后,我将其添加spring.main.sources: com.example.Application到了我的application.yml.它没有效果.

我目前的预感是我的web.xml 中的contextAttribute参数可能与我的问题有关.只是不确定我还能改变它.思考？

启动是否需要比Weblogic 10.3.3 Server支持的servlet版本更高的版本？这个版本是不是有点老了？？
