I'm getting error 404 while trying to access my spring boot app on Amazon Elastic Bean Stalk

Solution 1:

If you want Spring Boot With JSPs in Executable Jars

Keep in mind that we will ultimately place the JSP templates under src/main/resources/META-INF/resources/WEB-INF/jsp/

Note : define the template prefix and suffix for our JSP files in application.properties

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

Then your can run jar file using below command :

java -jar <your jar name>

 for your project you can below command

   java -jar  auth-1.3.5.RELEASE.jar

Solution 2:

JSP Limitations

When running a Spring Boot application that uses an embedded servlet container (and is packaged as an executable archive), there are some limitations in the JSP support.

With Jetty and Tomcat, it should work if you use war packaging. An executable war will work when launched with java -jar, and will also be deployable to any standard container. JSPs are not supported when using an executable jar. Undertow does not support JSPs. Creating a custom error.jsp page does not override the default view for error handling. Custom error pages should be used instead.

I have clone your GitHub project able to run project(if you follow below steps your problem will get solve definitely)

Step To run your project :

Step 1 : Create war package of your project

Step 2 : Run your war package using below command 

    java -jar <your war file name> 

    i.e for your project command should be like :

      java -jar  auth-1.3.5.RELEASE.war

Step 3 : Hit the URL  http://localhost:5000/

You can see the result in browser.

Nice explanation @dipak-thoke.

Just to add if anyone automating the deployment process (In my case, it was through CodeBuild And CodeDeploy), you can create Procfile and deploy the war. I have added Procfile into the root directory of the project and added it as an artifact. Hope this helps someone looking for same usage case :)

ProcFile:

web: java -jar <your_war_file>.war 

This is how my CodeBuild Buildspec looks like:

version: 0.2

phases:

  build:
    commands:
      # - command
      - ./gradlew bootWar
  post_build:
    commands:
      # - command
      - echo Build must be completed
      - mv build/libs/*.war <WarFileName>.war

artifacts:
  files:
    # - location
     - <WarFileName>.war
     - Procfile
  #name: $(date +%Y-%m-%d)
  #discard-paths: yes
  #base-directory: location
#cache:
  #paths:
    # - paths
