added a simple spring boot java app example

[johnscancella]

A very simple hello world using java and spring boot

[afeld]

This seems like a lot for a Hello World app...was a lot of it auto-generated or something?

@jcscottiii Being our resident Java expert, mind taking a look?

[jmcarp]

There are a few spring examples in https://github.com/cloudfoundry-samples. Speaking of which, could we contribute our examples to cloudfoundry-samples instead of managing our own project?

[afeld]

Nice! Had no idea that existed. #22

[LinuxBozo]

@afeld, couple of files were definitely autogenerated by gradle, the build runner. The core of the app itself is only 2 files, Main.java and HelloWorldController.java, and the test HelloWorldControllerTest.java

[afeld]

@johnscancella Thoughts about your implementation, vs. something like https://github.com/cloudfoundry-samples/hello-spring? Maybe we transfer this pull request there instead...?

[LinuxBozo]

@afeld The difference between this example, and the example at cloudfoundry-samples could set off a holy war.. Maven vs Gradle. ;-)

Also, this example is Spring Boot, the other is Spring MVC. Both Spring, but slightly different. Boot is current gen tech, and can configure/integrate MVC.

[DavidEBest]

Given that some of the files are generated, is it necessary to include the gradlew and gradlew.bat files?

[jcscottiii]

@DavidEBest yeah you need those two. essentially, if you don't have gradle installed locally yourself, you can just run the one for your OS and it'll be fine

[jcscottiii]

two options:

1. you can remove the .accept(MediaType.APPLICATION_JSON) part
2. or you also check the ContentType .andExpect(content().contentType()

[jcscottiii]

@johnscancella this looks good. :) just need you to also include the files from the gradle/wrapper folder

[johnscancella]

@afeld Yeah it is a bit verbose, but I didn't want anyone to have to install gradle. If you(or @jmcarp, @LinuxBozo, @jcscottiii) think that is an ok requirement to install gradle I can remove them.
@jcscottiii thanks for the compliments, updated as you suggested.

[johnscancella]

Ohh and @LinuxBozo yes definitely holy war when it comes to maven vs. gradle. I much prefer gradle, but if you think it will make a difference I can try and generate a maven pom file.

[afeld]

This works—we can always iterate, and maybe transfer this to a spring-boot-gradle repository under @cloudfoundry-samples.

[afeld]

Thanks @johnscancella for the contribution, and thanks everyone for the input!

[johnscancella]

no problem, glad I could help. +1 on merging with the cloudfoundry-samples at some point
