404 on Properly mapped SpringBoot RestController

I'm experiencing a little issue that is wasting a lot of my time...

I've created, for demonstration purposes, a simple SpringBoot application using the Eclipse New > Spring Starter Project.

Here is my Application class:

package it.asirchia;

//All needed imports

@SpringBootApplication
public class Application {

    public static HashMap<Long,Book> books = new HashMap<Long, Book>();
    public static HashMap<Long,Editor> editors = new HashMap<Long, Editor>();
    public static HashMap<Long,Person> authors = new HashMap<Long, Person>();

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

Then I've created the EditorsApis Controller:

package it.asirchia.apis;

//All needed imports

@RestController
@RequestMapping(value="/editors")
public class EditorsApis {

    private static long counter = 0;

    @RequestMapping(value="/", method=RequestMethod.GET)
    public HashMap<Long, Editor> getAllEditor(){
        return Application.editors;
    }

    @RequestMapping(value="/", method=RequestMethod.POST)
    public void postNewEditor(@RequestBody Editor editor){
        Application.editors.put(counter++, editor);
    }

    @RequestMapping(value="/{editorid}", method=RequestMethod.PUT)
    public void updateEditor(@PathVariable long editorid,
                                @RequestBody Editor editor){
        Application.editors.put(editorid, editor);
    }

    @RequestMapping(value="/{editorid}", method=RequestMethod.GET)
    public Editor getEditor(@PathVariable long editorid){
        return Application.editors.get(editorid);
    }

    @RequestMapping(value="/{editorid}", method=RequestMethod.DELETE)
    public void deleteEditor(@PathVariable long editorid){
        Application.editors.remove(editorid);
    }

}

And an AuthorsApis and a BooksApis controllers that are very similar to the EditorApis one.

Of course I've created too all the three Pojos: Editor.class, Person.class and Book.class

I've started up the Eclipse embedded Spring runtime and I can see that all the paths are properly mapped:

INFO [main] s.w.s.m.m.a.RequestMappingHandlerMapping Mapped " {[/authors/],methods=[GET]}" onto public java.util.HashMap it.asirchia.apis.AuthorsApis.getAllAuthors()

And so on and so forth for all the other Rest APIs I've implemented. The last three lines of the log are:

Starting beans in phase 0

Tomcat started on port(s): 8080 (http)

Started Application in 5.547 seconds (JVM running for 6.169)

Ok, for me wverything is properly configured, up and running. But when I try to invoke 

GET /authors HTTP/1.1
Host: localhost:8080

I obtain: 

{
"timestamp": 1507286437765,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/authors"
}

And the same happens for ALL the REST APIs I've implemented. Any idea about the reason of this problem? Thank you.

The following mapping will work localhost:8080/authors/ for you.Since in your method mapping GET you have added the "/" so you should provide the trailing slash in URL also. If you want mapping like this localhost:8080/authors then follow the below code,

@RequestMapping(value={"","/"}, method=RequestMethod.GET)
public HashMap<Long, Editor> getAllEditor(){
    return Application.editors;
}

The above will accept,

1) localhost:8080/editors

2) localhost:8080/editors/

Hope this will help.

Can you just try to add a action content in value.Here only specifying only a "/".Like

 @RequestMapping(value="/updateEditor", method=RequestMethod.GET)

If you need to add any path variable,you can modify the same with following,

@RequestMapping(value="/updateEditor/{editorid}", method=RequestMethod.PUT)

Just try this method also.
