如何将Spring Boot与Servlet 3.0容器集成在一起并使其在Websphere 8.5.5服务器中工作？

Question

I have a working project developed with Spring boot, spring boot security and spring data rest with Maven.

As a standalone class working fine. WAR deployment in Tomcat also working fine. I have generated an EAR out of the WAR with Maven and deployed in WAS 8.5.5 is not working.

Standalone Java class which is woking fine with embedded Tomcat also with external Tomcat 7. Same failing to start with websphere not sure is any other configuration I am missing?

    package com.marsh.forms;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.DispatcherServlet;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@EnableWebMvc
@ComponentScan
@EnableAutoConfiguration
@EnableConfigurationProperties
public class FormsRestApplication2 extends SpringBootServletInitializer {


    public static void main(String[] args) throws Exception {
        ApplicationContext ctx = SpringApplication.run(
                FormsRestApplication2.class, args);

    }   

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

    private static Class<FormsRestApplication2> applicationClass = FormsRestApplication2.class;

    @Bean
    // Magic entry
    public DispatcherServlet dispatcherServlet() {
        DispatcherServlet ds = new DispatcherServlet();
        ds.setThrowExceptionIfNoHandlerFound(true);
        return ds;
    }

}

Ear generated successful and I can see proper update in application.xml about was project with context root. War also generated fine with classes and lib metaInf info.

Manifest-Version: 1.0

Created-By: Apache Maven 3.0.4
Archiver-Version: Plexus Archiver

Couple of issues I noticed:

1. the issue is EAR deploying in server but not WAR and I don't see either spring boot starter or my classes getting loaded or publishing my spring rest data URLs:

2. This may be because of version mismatches but i am using jDK7 in all compiler, runtime and WAS 8.5.5 running in JDK7.

I have used latest spring boot version for "@ControllerAdvice(basePackageClasses = RepositoryRestExceptionHandler.class)" class is required.

Answer 1

Resolution: I could able to resolve this issue with servlet2.5 container meaning i have changed web.xml like below and followed below thread steps to make it work as i could not get quick solution to make it work with servlet 3.0 in WAS 5.5.5.0

since i have changed the container version i have also lowered the hibernate and spring boot jpa version to execute my project.
