In this guides,PUT, PATCH, and DELETE REST calls to either replace, update, or delete existing records.
But in the case ,if the field does not exist,insert one ;Else update the field,How to do it?

I am getting the following error on running the complete package:

2017-06-11 12:54:12.973 INFO 25961 --- [ main] org.mongodb.driver.cluster : No server chosen by WritableServerSelector from cluster description ClusterDescription{type=UNKNOWN, connectionMode=SINGLE, serverDescriptions=[ServerDescription{address=localhost:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.ConnectException: Connection refused (Connection refused)}}]}. Waiting for 30000 ms before timing out

I suspect it is related to this stackoverflow post: https://stackoverflow.com/questions/31933821/cant-connect-to-local-monogodb-from-java.

So essentially your code has a race condition between the mongodb database and the code (which is an error that is not always reproducible, as it depends on the speed and operating environment of the users computer). I have had the same issue with your other mongodb tutorial and so will be opening an issue there as well. It looks like to solve this it will require a refactor, but as I am new to java it is something that I cannot do on my own. Please fix!

I'm guessing intro section of the README

This guide walks you through the process of creating an application that accesses graph-based data through a hypermedia-based RESTful front end.

should change to

This guide walks you through the process of creating an application that accesses document-based data through a hypermedia-based RESTful front end.

Though the application code is not changed and we work with the generated one. The block of text describing the annotation is there and there is not mentioned what it is about or to what file it belongs. I suggest to tidy it up a little bit.

Hi,

I'm trying to expose resource IDs in my project by using RepositoryRestConfiguration#exposeIdsFor(). It wasn't working in my larger application, so I came all the way back to the starter project to see if I'd messed something up somehow.

But I'm still not able to see IDs in the JSON responses with the following custom configuration:

@Configuration
public class CustomRepositoryRestMvcConfiguration extends SpringBootRepositoryRestMvcConfiguration {

  @Override
  protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
    config.exposeIdsFor(Person.class);
  }
}

Application.java:

@SpringBootApplication
@Import(CustomRepositoryRestMvcConfiguration.class)
public class Application {

  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

Am I doing something obviously wrong here? All the examples I've found online indicate that this should work. Maybe I've found a regression, but I doubt it.

I hope this repo is the right place to report this issue, but apologies if it isn't.

Thanks in advance for any help!

An ongoing task is to keep the Spring Boot version current in the build files:

To do so, update the following files:

complete/build.gradle
complete/pom.xml
initial/build.gradle
