java - 部署到 Weblogic 11g 的 Spring Boot 应用程序无法启动

Question

我在将 Spring Boot 应用程序部署到 Weblogic 10.3.3 服务器时遇到了一些问题。我拼命地祈祷，希望有人以前见过这个问题。我使用 Weblogic 的管理控制台来执行部署(这似乎很顺利)，但是当我尝试启动应用程序时，我从 Weblogic 收到错误消息:

应用程序使用 spring-boot-legacy 和 web.xml 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

</servlet-mapping>

weblogic.xml

<wls:weblogic-web-app

通过堆栈跟踪，似乎 Spring Boot 的 BeanDefinitionLoader 类试图加载源类(在我的例子中，只是 com.example.Application)但失败了，因为它没有看到它作为类、资源或包。在此处查看 BeanDefinitionLoader 类:BeanDefinitionLoader.java (第 187 行)，看来我的应用程序类应该作为类加载。就像我提到的，它在 Tomcat 中运行良好，但在 Weblogic 中却不行。

是否缺少某些特定于 Weblogic 的内容？会不会是文件编码问题？我的 web.xml 中是否缺少某些内容？

感谢您的宝贵时间!

更新#1

在用尽 Google 和 StackOverflow 进行尝试后，我将 spring.main.sources: com.example.Application 添加到我的 application.yml 中。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。只是不确定我还能把它改成什么。想法？

检查您构建的 war 是否使用与正在运行的 Weblogic 服务器相同的 Java 版本。例如，如果它是 1.6，则在运行 gradle build 之前将 JAVA_HOME 设置为您的 1.6 JDK。
