使用Spring启动将RESTful服务部署到AWS

Question

我正在尝试将一个简单的Spring Boot RESTful服务部署到AWS beanstalk。我正在使用mvn clean包来获得战争。这是我的代码：

 //@SpringBootApplication
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {

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

package hello;

import java.util.concurrent.atomic.AtomicLong;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();

@RequestMapping("/greeting")
public Greeting greeting(@RequestParam(value = "name", defaultValue = "World") String name) {
    return new Greeting(counter.incrementAndGet(), String.format(template, name));
}

@RequestMapping("/hello/{name}")
String hello(@PathVariable String name) {
    return "Hello, " + name + "!";
}
}

但是当我尝试访问（load-balancer-url）/ hello / World时，我收到404错误。对我做错的任何帮助？谢谢。

Spring Boot | Create a deployable war file

来自文档：

  

生成可部署的war文件的第一步是提供一个   SpringBootServletInitializer子类并覆盖其配置   方法。这利用了Spring Framework的Servlet 3.0支持和   允许您在应用程序启动时配置您的应用程序   servlet容器。通常，您更新应用程序的主类   扩展SpringBootServletInitializer：

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

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

}

Answer 2

您也可以使用ElasticBeanstalk安装它。 首先，您需要战争文件。转到应用程序文件夹，然后按照以下步骤使用Maven进行打包。

mvn package -DskipTests

（在Windows计算机中，复制mvnw.cmd并将副本命名为mvnw.bat）

完成打包任务后，您将在“目标”文件夹中找到您的projectname-snapshot.war。

将war文件上传到Beanstalk之后，点击配置更多选项 并转到软件部分，只需将SERVER_PORT设置为5000，如下所示。设置后，点击创建环境。
