我正在尝试将我的java war部署到弹性beanstalk实例，并且无法超越以下错误：
502 Bad Gateway
路线发生了这种情况：http://sample-env.24xzv8dhr2.us-east-1.elasticbeanstalk.com/
我完全确定这是正确的路线，因为它可以在本地工作。这是我的Java代码
@Controller
public class JSONController {
@ResponseStatus(HttpStatus.OK)
@RequestMapping(value = "/", method = RequestMethod.GET) public void ping()
{
System.out.println("System Working As Designed!");
}
....
这是我的日志：

入境/出境应该没问题：

尝试更正此AWS Elastic Beanstalk错误，我们将不胜感激。健康检查也失败了说“健康状况下降”。
