AWS Elastic Beanstalk上的Spring Boot/Tomcat仅显示404页面

Question

我有一个Spring Boot应用程序,可以在Tomcat下的localhost上正常运行.当我将其打包为WAR并将其部署在Elastic Beanstalk上时,我只获得404页面.我尝试了许多不同的调整试图让它工作,但我不知所措.

我已将包装配置为WAR,IntelliJ生成工件:

<groupId>com.ideaEngine</groupId>
<artifactId>app_deployment</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <start-class>com.xxxxxxxx.WebappApplication</start-class>
    <java.version>1.8</java.version>
</properties>

我也把Tomcat包括在内

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

Elastic Beanstalk服务器是运行Tomcat 8 Java 8的64位Amazon Linux 2016.03 v2.2.0

Localhost JVM是jdk1.8.0_71.jdk

应用程序对象是:

@SpringBootApplication
public class WebappApplication {

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(WebappApplication.class);
    }

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(WebappApplication.class, args);
        System.out.println("Running............");
    }
}

我有一个测试控制器,我用它来确保一切正常:

@RestController
public class HelloController {

    @RequestMapping("/")
    public String index() {
        return "Greetings from Spring Boot!";
    }
}

...它会产生404错误.

我已将.war文件命名为Webapp.war,并将其命名为ROOT.war,并尝试在.com /和/ ROOT /和/ Webapp /中访问它

他们都生产404.

日志文件显示应用程序正在部署到服务器:

Deployment of web application directory /var/lib/tomcat8/webapps/ROOT has finished in 2,143 ms

部署后,所有文件都在/ var/lib/tomcat8/webapps/ROOT中解压缩.

META-INF/MANIFEST.MF似乎很好:清单版本:1.0实现 - 标题:xxxxxxxxxxx实现 - 版本:0.0.1-SNAPSHOT内置:cdc实现 - 供应商-Id:com.xxxxxxxxx创建者:IntelliJ IDEA Build-Jdk:1.8.0_71 Main-Class:com.xxxxxxxxx.WebappApplication

健康读作"好"

Environment health has transitioned from Info to Ok. Application update completed 58 seconds ago and took 15 seconds.

我一直在梳理有关AWS部署的所有其他问题,并且已经空洞.

再次,该应用程序在我的本地计算机上运行良好.

关于我缺少什么的任何想法？

谢谢!

所以我有一个类似的问题。我遵循了mkyong https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/的指示 ，这似乎解决了我的问题。

查看您的代码，我注意到您的WebappApplication没有扩展SpringBootServletInitializer。也许尝试像这样扩展SpringBootServletInitializer。

@SpringBootApplication
public class WebappApplication extends SpringBootServletInitializer{

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

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(WebappApplication.class, args);
        System.out.println("Running............");
    }
}
