问题：

无法访问Openshift上已部署的Spring Boot应用程序（war）的endpoint

富钧
2023-03-14

我正在同时试验Spring boot和openshift，不幸的是，我遇到了一个我无法找到的问题。

我用Spring启动的初始值设定项创建了一个应用程序。创建了几个Rest控制器（你好，世界喜欢）

这是我的应用程序（主）

@Configuration 
@ComponentScan 
@EnableAutoConfiguration 
public class Application extends SpringBootServletInitializer {

Logger logger = LoggerFactory.getLogger(Application.class);

public static void main(String[] args) {
    Class[] sources = {Application.class};
    SpringApplication.run(sources, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    // Customize the application or call application.sources(...) to add sources
    return application.sources(Application.class);
}

/* It retrieves all the beans that were created either by your app or were automatically added thanks to Spring Boot. It sorts them and prints them out. */
@Bean
public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
    return args -> {

        StringBuilder builder = new StringBuilder();

        builder.append("Let's inspect the beans provided by Spring Boot:\n");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames) {
            builder.append(beanName);
            builder.append("\n");
        }

        logger.info(builder.toString());
    };
}
}

我可以在本地启动应用程序（通过智能和冬虫）。我可以看到应用程序日志记录并访问所有endpoint，没有任何问题。

pom.xml是这样的：

因此，根据我的理解，WAR文件是根据Openshift（minishift）中的LOGS正确创建和部署的：

正如您在日志中看到的，应用程序似乎被正确加载了。Application类上的日志记录报告加载的beans的列表(为了简洁起见，我将其缩短了)。Spring boot还记录endpoint的注册，但是当我试图访问minishift公开的登录页面时，我得到了标准的wildfly登录页面，当我试图查询控制器时，web服务器返回404 not found。

关于哪里出错了/我应该如何调试它，有什么提示吗？

免责声明:提前道歉，我对Spring boot和Openshift没有经验:)如果你需要其他信息，请让我知道。

应用程序未部署在 Web 服务器的根目录上。在文件夹 /src/主/网络应用/WEB-INF/ 中，我不得不为 JBoss 添加一个名为 jboss-web 的部署描述符.xml
