托管Spring Boot应用

Question

I could not host my spring boot app to Amazon Web Services: Elastic Beanstalk. I did follow some video tutorials and stack overflow posts. still helpless. I want to host my war file to AWS and run it successfully. Here is my pom.xml and other stuff. it works well in the local. but after deploying to aws it does not work. the health status shown is severe.

Answer 1

There are a couple of things wrong in your pom.xml

1. mixing version of Spring Boot 1.5.2 and 1.5.9 (never mix versions of a framework).
2. Inclusion JPA 1.0 API whereas you use a JPA 2.0 provider
3. Generally AWS BeanStalk want your app to run on port 5000.

For 1 remove the <version> tag in your conflicting dependency and/or change the version of Spring Boot to the matching version.

Remove the JPA 1.0 API.

AWS expects your application to run on port 5000. Either specify this in the application.properties to be the port or specify a environment variable SERVER_PORT with value 5000 in your AWS environment. See Deploying a Spring Boot Application on AWS and especially the section on how to specify the port.
