Can't load swagger-ui.html

[nvtuan305]

When I access http://localhost:8080/swagger-ui.html, I got the below message. But accessing http://localhost:8080/v2/api-docs page return the API json content.

Unable to infer base url. This is common when using dynamic servlet registration or when the API is behind an API Gateway. The base url is the root of where all the swagger resources are served. For e.g. if the api is available at http://example.org/api/v2/api-docs then the base url is http://example.org/api/. Please enter the location manually

Thank you!

As of springfox 2.9.2 breaking changes came into:
springfox.documentation.swagger.web.SwaggerResource
springfox.documentation.swagger.web.UiConfiguration

The configs in SwaggerJsonController must be updated like:

    //https://stackoverflow.com/questions/47395549/springfox-swagger-ui-from-existing-json
    // springfox.documentation.swagger.web.SwaggerResource
    private static String swaggerResource = "[\n" +
            "  {\n" +
            "    \"name\": \"default\",\n" +
            "    \"url\": \"/v2/api-docs\",\n" +
            "    \"swaggerVersion\": \"2.0\"\n" +
            "  }\n" +
            "]";

    // springfox.documentation.swagger.web.UiConfiguration
    private static String uiConfiguration = "{\n" +
            "\"deepLinking\": true,\n" +
            "\"displayOperationId\": false,\n" +
            "\"defaultModelsExpandDepth\": 1,\n" +
            "\"defaultModelExpandDepth\": 1,\n" +
            "\"defaultModelRendering\": \"example\",\n" +
            "\"displayRequestDuration\": false,\n" +
            "\"docExpansion\": \"none\",\n" +
            "\"filter\": false,\n" +
            "\"operationsSorter\": \"alpha\",\n" +
            "\"showExtensions\": false,\n" +
            "\"tagsSorter\": \"alpha\",\n" +
            "\"validatorUrl\": \"\",\n" +
            "\"apisSorter\": \"alpha\",\n" +
            "\"jsonEditor\": false,\n" +
            "\"showRequestHeaders\": false,\n" +
            "\"supportedSubmitMethods\": [\n" +
            "\"get\",\n" +
            "\"put\",\n" +
            "\"post\",\n" +
            "\"delete\",\n" +
            "\"options\",\n" +
            "\"head\",\n" +
            "\"patch\",\n" +
            "\"trace\"\n" +
            "]\n" +
            "}";

    // springfox.documentation.swagger.web.SecurityConfiguration
    private static String securityConfiguration = "{}";

I like this example project because you do not need springfox-swagger2 as a library, it will just work with springfox-swagger-ui and my exisiting swagger.json generated by kongchens maven plugin.

http://localhost:8080/v2/api-docs is returning back the json from swagger.json but the http://localhost:8080/swagger-ui.html is giving me back 500 response
