Creating an executable using maven for spring

Question

I'm trying to make an executable jar of a spring application. However whenever I try to run it using java -jar jar file, I get the error:

Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

I'm running using

mvn clean compile assembly:single

When I use Eclipse to run the server, it runs fine. Here is my pom file:

I know this has been answered on other threads, but none of them worked for me, I tried creating an executable jar file from eclipse, but that had other issues.

You did try things ? Like what ? Tell us so that we dont repeat them. Did you read [this](http://stackoverflow.com/questions/21783391/spring-boot-unable-to-start-embeddedwebapplicationcontext-due-to-missing-embedd) ? And [this](http://stackoverflow.com/questions/34022580/spring-boot-error-unable-to-start-embeddedwebapplicationcontext-due-to-missing) ? What about [this](https://github.com/spring-projects/spring-boot/issues/861) one ? I have no idea what these things are but I know setting `@EnableAutoConfiguration` solved it for a lot of people. We are not a Googling service, use it urself. — UDKOX, May 15 '16 at 02:31
You tried those ? Which ones ? Add them to the post. We won't try to help if you don't tell us what you already tried. `I tried creating an executable jar file from eclipse, but that had other issues.` What issues ? Did you try to fix them ? Invest some time before asking. — UDKOX, May 15 '16 at 02:37
@kryger Yes, from a different answer, running mvn sprin-boot:run ran the web server. I had to change my java version from 1.8 to 1.7 due to some of my code. I want to package it into a jar so that it can run on a different server without any additional packages. — spearmunkie, May 16 '16 at 02:42

I will firstly run the command from command line to verify if the application can run from command line.

mvn spring-boot:run

Normally, I build the fat jar by running

mvn clean install

And then take the .jar file from #WORKING_DIR#/target folder. Hope this can shed some light for your debugging.

Thank Ro Yo Mi for your information. I haven posted my answers to StackOverflow recently and hence don't know much about the rule. – DoT May 16 '16 at 03:43
