REST API - Swagger + Java + Jersey wrong listing path and additional apis

Question

In my project I am using Maven, Jetty, Swagger, Java and Jersey for creating REST API. I also use Swagger to create nice-looking documentation for my API.

Almost everything is ok instead three issues. At the first - this is my web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

1) How to remove api-docs from the beginnig of listingPath?

{
  "apiVersion": "1.0",
  "swaggerVersion": "1.1",
  "basePath": "http://localhost:8080/rest",
  "apis": [
    {
      "path": "/api-docs/resources",
      "description": ""
    },
    {
      "path": "/api-docs/employee",
      "description": ""
    }
  ]
}

And I want to remove /api-docs at the beginning of the path..

2) How can I remove "/api-docs/resources" from apis? I use only 'employee' class, not 'resources'.

3) If I type http://localhost:8080/rest/api-docs/employee I have my methods and '/' main URL which is empty. Can I remove it?

I've tried a lot of configurations. Am I missed something?

I've solved this in this way:

Save api-docs.json generated by Swagger to hard-drive
Edit generated JSON as you need
Copy this file to ~/src/main/webapp/swagger-ui/api-docs.json
Put http://localhost:8080/swagger-ui/api-docs.json to your discoveryUrl path in index.html of you /swagger-ui directory

This method needs from you, that you have to modify by yourself you main listing if anything change but it's safe and working solution.

My api-docs.json looks like this:

{
    "apiVersion": "1.0",
    "swaggerVersion": "1.1",
    "basePath": "http://localhost:8080/rest",
    "apis": [
        {
            "path": "/api-docs.json/employee",
            "description": ""
        }
    ]
}

and swagger-ui/index.html settings

<script type="text/javascript">
    $(function () {
        window.swaggerUi = new SwaggerUi({
            discoveryUrl:"http://localhost:8080/swagger-ui/api-docs.json",
            apiKey:"special-key",
            dom_id:"swagger-ui-container",
            supportHeaderParams: false,
            supportedSubmitMethods: ['get', 'post', 'put'],
            onComplete: function(swaggerApi, swaggerUi){
                if(console) {
                    console.log("Loaded SwaggerUI")
                    console.log(swaggerApi);
                    console.log(swaggerUi);
                }
              $('pre code').each(function(i, e) {hljs.highlightBlock(e)});
            },
            onFailure: function(data) {
                if(console) {
                    console.log("Unable to Load SwaggerUI");
                    console.log(data);
                }
            },
            docExpansion: "none"
        });

        window.swaggerUi.load();
    });

</script>
