Not able to get Swagger UI with spring boot - spring-boot

Question

I am following the article at http://raibledesigns.com/rd/entry/documenting_your_spring_api_with.
Everything works fine but not able to integrate Swagger UI.
http://localhost:8080/docs/index.html
results in /error redirection.

Answer 1

I know this is an old question but maybe this will help someone with the similar problem in the future.
I followed similar tutorial to the one you mentioned and I made it work without a problem. I put my own document on how to setup a Swagger with UI in a Spring boot project couple of weeks ago. Maybe it will help you out since it is shorter and more up-to-date.
Add Maven dependencies
Stick these in your pom.xml:
<dependency>
<groupId>com.mangofactory</groupId>
<artifactId>swagger-springmvc</artifactId>
<version>1.0.2</version>
<type>jar</type>
</dependency>
Add Swagger UI
Download the Swagger UI from github. Copy the dist folder into your webapp directory and rename dist to swagger (or any name you like).
Open the index.html file inside the copied directory and change the url in the first javascript function so it points to the /api-docs endpoint:
var url = window.location.search.match(/url=([^&]+)/);
if (url && url.length > 1) {
url = decodeURIComponent(url[1]);
} else {
url = "/project-name/api-docs";
}
Configure Swagger
Create a SwaggerConfig.java class and configure swagger there:
#Configuration
#EnableSwagger
#EnableAutoConfiguration
public class SwaggerConfig {
private SpringSwaggerConfig springSwaggerConfig;
#Autowired
public void setSpringSwaggerConfig(SpringSwaggerConfig springSwaggerConfig) {
this.springSwaggerConfig = springSwaggerConfig;
}
#Bean
public SwaggerSpringMvcPlugin customImplementation() {
return new SwaggerSpringMvcPlugin(this.springSwaggerConfig)
// Root level documentation
.apiInfo(new ApiInfo("Swagger-demo JSON API", "This service provides a JSON representation the service API", null, null, null, null))
.useDefaultResponseMessages(false)
// Map the specific URL patterns into Swagger
.includePatterns("/greeting.*");
}
}
Your swagger should be up and running now. Try accessing /project-name/swagger/index.html.

Answer 2

I'm answering this with swagger2 configuration inside a gradle based spring boot application. Following are the configuration required for Swagger2.
Add Gradle Configuartion
Add Gradle dependencies inside build.gradle file
dependencies {
compile("io.springfox:springfox-swagger2:2.0.2")
compile("io.springfox:springfox-swagger-ui:2.0.2")
}
Swagger2 Confugration Class
#Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket userApi() {
return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any()).build().pathMapping("/")
.directModelSubstitute(LocalDate.class, String.class)
.genericModelSubstitutes(ResponseEntity.class)
.alternateTypeRules(newRule(
typeResolver.resolve(DeferredResult.class,
typeResolver.resolve(ResponseEntity.class, WildcardType.class)),
typeResolver.resolve(WildcardType.class)))
.useDefaultResponseMessages(false)
.globalResponseMessage(RequestMethod.GET,
newArrayList(new ResponseMessageBuilder().code(500).message("500 message")
.responseModel(new ModelRef("Error")).build()))
.securitySchemes(newArrayList(apiKey())).securityContexts(newArrayList(securityContext()))
.apiInfo(apiInfo());
}
#Autowired
private TypeResolver typeResolver;
private ApiKey apiKey() {
return new ApiKey("mykey", "api_key", "header");
}
private SecurityContext securityContext() {
return SecurityContext.builder().securityReferences(defaultAuth())
.forPaths(PathSelectors.regex("/anyPath.*")).build();
}
List<SecurityReference> defaultAuth() {
AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
authorizationScopes[0] = authorizationScope;
return newArrayList(new SecurityReference("mykey", authorizationScopes));
}
#Bean
SecurityConfiguration security() {
return new SecurityConfiguration("123456", "test-app-realm", "clientapp", "apiKey");
}
#Bean
UiConfiguration uiConfig() {
return new UiConfiguration("validatorUrl");
}
private ApiInfo apiInfo() {
ApiInfo apiInfo = new ApiInfo("DSM API", "API for DSM", "1.0.0", "termsOfServiceUrl",
"nijo#ndimensionz.com", null, null);
return apiInfo;
}
}
Add Swagger UI
Download the Swagger UI from github. Copy the dist folder into your src/main/resources/static directory and rename dist to swagger
HomeController.class
#Api(basePath = "/", value = "/", description = "Home Controller")
#Controller
public class HomeController {
#RequestMapping("/")
public String home() {
return "redirect:swagger-ui.html";
}
}
MyApplication.class
#SpringBootApplication
#ComponentScan(basePackageClasses = SwaggerConfig.class)
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}
Configure your spring boot application with dependencies and run to see the API.
the url will be http://localhost:8080/v2/swagger-ui.html
you can also customize this as above answer.

I too face same problem. I was able to see json but not swagger ui after adding dest folder aslo. In initialize class which extends SpringBootServletInitializer I added below method then it was working perfect
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SampleWebStaticApplication.class);
}
please refer link

Here is my working configuration incase it helps anyone else
#Configuration
#EnableSwagger2
#Profile({"!production"})
public class SwaggerConfiguration extends WebMvcConfigurerAdapter {
#Autowired
private ServletContext servletContext;
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.host("localhost")
.directModelSubstitute(LocalDate.class, Date.class)
.pathProvider(new RelativePathProvider(servletContext) {
#Override
public String getApplicationBasePath() {
return "/docs";
}
})
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
}
Since I am also using Spring security, I also had to add the following to my whitelist:
private String[] swaggerWhiteList = {"/v2/api-docs", "/swagger-resources/configuration/ui", "/swagger-resources", "/swagger-resources/configuration/security", "/swagger-ui.html", "/swagger.json", "/webjars/**"};
Then I could access it using the following url:
http://localhost:8080/docs/swagger-ui.html
