spring - 包含在 openshift tomcat 上手动部署的 spring boot 应用程序的 WAR 不起作用

Question

我创建了一个 Spring Boot 应用程序，然后创建了一个 war。

在我的本地服务器上，应用程序可以正常运行。

我将此应用程序重命名为 ROOT.war，使用 git 将其放入 webapps 目录并重新启动服务器，从而将此应用程序添加到 JBOSSEWS 盒中。

但是我总是找不到404。

tomcat 日志是:

确保您的主类 Application 扩展了 SpringBootServletInitializer

Initialize the servlet

By converting this into a WAR file with no XML files, you need a different signal to the servlet container on how to launch the application.

import org.springframework.boot.context.web.SpringBootServletInitializer;

public class HelloWebXml extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}

HelloWebXml is a pure Java class that provides an alternative to creating a web.xml. It extends the SpringServletInitializer class. This extension offers many configurable options by overriding methods.
