在websphere 8.5.5.9上初始化Spring Boot

Question

i'm trying to run a Spring boot application on Webpshere 8.5.5.9

The code works fine if runned as java main on a embedded tomcat, but if i try to deploy on webpshere, the EAR starts with no error but no rest services are deployed. I don't see in server console the SPRING BOOT LOG. It's not started.

If i make a get on server context path i reveive an hello world! (ear deployed successfully) but at the address of rest service i get a 404 (File not found)

I used spring boot as BOM insted of parent because i already have a parent. My software stack is:

• Java 8
• JEE 6
• Spring boot 1.5.9 RELEASE
• Maven 3.5.X
• Websphere 8.5.5.9

Any suggestion? Thanks

START CLASS

    @SpringBootApplication
    @Configuration
    @EnableAutoConfiguration(exclude = {
        org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
        org.springframework.boot.actuate.autoconfigure.ManagementWebSecurityAutoConfiguration.class})
    public class ApplicationConfiguration extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        System.out.println("*** CONFIGURING ***");
        return application.sources(ApplicationConfiguration.class);
    }

    public static void main(String[] args) {
        //ApplicationContext ctx = 
        System.out.println("*** STARTING MAIN ***");
        SpringApplication.run(ApplicationConfiguration.class, args);
        //System.out.println(ctx);
    }

    }

CONTROLLER

@RestController
public class ExampleController {

    @GetMapping("/sayhello")
    String home() {
        return "Hello World! Test";
    }
}

A WAR is packed in a EAR Important part of POM.xml of WAR is:

Answer 1

1. Make sure Webspehere is pointing to sdk 1.7_64 or 32 Please check documention on how to change profile to use sdkname {PROFILE}\\bin>managesdk.bat -listEnabledProfile -profileName {PROFILE} -verbose see it is displaying 1.7_64 or 1.7_32

{PROFILE}\\bin>managesdk.bat -enableProfile -profileName {PROFILE} -sdkname 1.7_64 -enableServers

2. Change JVM Argument to -Dclassinfocachesize=10000

This worked for me. Please try
