在 TomEE 7.1.0 中部署 Spring-boot Web 项目

Question

我从 STS 创建了一个简单的基于 Spring Boot Web 的项目，这是我的 pom 文件。

我已经打包成一个war文件并在TomEE中进行部署，我得到了错误。

不知道出了什么问题......

我们在将 Spring Boot 应用程序作为战争部署到 TomEE 7.1.0 时遇到了类似的问题。容器，我们通过 META-INF/context.xml 中的条目解决了它，用于应用程序战争。

<?xml version='1.0' encoding='utf-8'?>
<Context path="/app/service">
  <Loader delegate="true"/>
</Context>

https://tomcat.apache.org/tomcat-8.0-doc/config/loader.html

属性=委托

如果您希望类加载器遵循标准的 Java2 委托模型，则设置为 true，并在查看 Web 应用程序之前尝试从父类加载器加载类。设置为 false（默认值）以让类加载器先查看 Web 应用程序内部，然后再要求父类加载器查找请求的类或资源。

https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

因此，从 Web 应用程序的角度来看，类或资源加载按以下顺序查看以下存储库：

1. JVM 的引导类
2. /WEB-INF/Web 应用程序的类
3. /WEB-INF/lib/*.jar 您的 Web 应用程序
4. 系统类加载器类
5. 通用类加载器类

如果 Web 应用程序类加载器配置为 <Loader delegate="true"/>，则顺序变为：

1. JVM 的引导类
2. 系统类加载器类
3. 通用类加载器类
4. /WEB-INF/Web 应用程序的类
5. /WEB-INF/lib/*.jar 您的 Web 应用程序
