java - 无法将简单的 Spring Boot Web 应用程序部署到 OpenShift

Question

我有一个 .war 文件，当我将其复制到本地 Tomcat 9 实例中的 webapps 文件夹时，它会成功部署。不知何故，当我尝试在 Openshift 设备(Tomcat 7)上运行它时，它没有被部署。我正在采取的步骤:

0:我克隆了远程仓库。

1:我将war文件复制到git仓库中的webapps文件夹。

2:我将它推送到远程仓库并得到输出:

• 在 repo 中有一个 .pom 文件和我删除的 src 文件夹。

主要java:

@SpringBootApplication
@ComponentScan({"controllers", "rest"})
public class SimpleAppApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        ConfigurableApplicationContext ctx = SpringApplication.run(SimpleAppApplication.class, args);

    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(applicationClass);
    }

    private static final Class<SimpleAppApplication> applicationClass = SimpleAppApplication.class;

}

根 Controller :

@RestController
public class MainController {


    @RequestMapping("/")
    public String text (){
        return "ja pierdole wygral jebany!";
    }

}

编辑我检查了服务器日志，发现了很多此类错误:

目前来看四个问题:

由于OpenShift Tomcat Processing Annotations Error Deploying War

• Tomcat 版本

可以通过 pom.xml 中的属性更改 Tomcat 版本

    <properties>
        <java.version>1.7</java.version>
        <maven.compiler.source>1.7</maven.compiler.source>
        <maven.compiler.target>1.7</maven.compiler.target>
        <start-class>com.example.SimpleAppApplication</start-class>
        <tomcat.version>7.0.54</tomcat.version>
    </properties>

• OpenShift Java 版本

由于 https://developers.openshift.com/servers/tomcat/getting-started.html#other，检查 OpenShift git repo 上是否存在标记文件 .openshift/markers/java7

您可以选择添加标记 .openshift/markers/skip_maven_build 以跳过 Maven 构建。

• 加载 Controller

如果 PagesController.java 在 controllers 包中

    @Configuration
    @EnableAutoConfiguration
    @ComponentScan("controllers")
    @RestController
    public class SimpleAppApplication extends SpringBootServletInitializer {

        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application;
        }

        public static void main(String[] args) {
            SpringApplication.run(SimpleAppApplication.class, args);
        }
    }
