How to have custom context Path for Swagger Url in OpenApi3 Springboot Application

I am migrating from springfox to OpenApi3 in my Springboot project as we have a requirement to upgrade to latest springboot with version 2.7.0
I need to configure custom contextPath for different environments like below
dev - https://qa.swagger.com/dev/api/myApp/swagger-ui/index.html
qa - https://qa.swagger.com/api/myApp/swagger-ui/index.html
uat - https://uat.swagger.com/api/myApp/swagger-ui/index.html#/

// SwaggerConfig class
#Configuration
#Profile({ "local", "dev", "qat", "uat" })
public class SwaggerConfig {
#Bean
public OpenAPI openAPI() {
return new OpenAPI().info(info());
}
private Info info() {
return new Info()
.title(title)
.version(version)
.license(new License().name(licenseName).url(licenseUrl));
}
}
//application.properties
spring.application.name=myApp
server.servlet.context-path=/api/${spring.application.name}
With the above configuration, I am able to run swagger using below url and getting all required response from controller apis
http://localhost:8082/api/myApp/swagger-ui/index.html#/
For configuring the Swagger url for other environments,I tried to create a listener configuration class like below which didn't work
#Component
public class SwaggerListener implements ApplicationListener<ApplicationPreparedEvent> {
final ApplicationPreparedEvent event = null;
#Override
public void onApplicationEvent(final ApplicationPreparedEvent event) {
ConfigurableEnvironment environment = event.getApplicationContext().getEnvironment();
Properties properties = new Properties();
properties.put("springdoc.swagger-ui.path", swaggerPath(event));
environment.getPropertySources().addFirst(new PropertiesPropertySource("programmatically", properties));
}
private String swaggerPath(final ApplicationPreparedEvent event) {
String basePath = null;
String swagger = "swagger-ui/index.html";
ConfigurableEnvironment environment = event.getApplicationContext().getEnvironment();
String[] profilesList = environment.getActiveProfiles();
List<String> profiles = Arrays.asList(profilesList);
String contextPath = environment.getProperty("server.servlet.context-path");
if (profiles != null && (profiles.contains("local"))) {
basePath = swagger;
} else if (profiles != null && profiles.contains("dev")) {
basePath = "/dev/api/myApp/" + swagger;
} else if (profiles != null && (profiles.contains("qat") || profiles.contains("uat"))) {
basePath = "/api/myApp/";
}
return basePath;
}
}
Adding above listener to main class
#SpringBootApplication(scanBasePackages = { "com.myApp.controller" })
#OpenAPIDefinition
public class myApi {
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(myApi.class);
springApplication.addListeners(new SwaggerListener());
springApplication.run(args);
}
}
The above listener configuration is not working
Can anyone help me out here and let me know what am I missing here ?

I have been looking the same. This documentation help me:
To enable the support of multiple OpenAPI definitions, a bean of type
GroupedOpenApi needs to be defined.
For the following Group definition(based on package path), the OpenAPI
description URL will be : /v3/api-docs/stores
#Bean
public GroupedOpenApi storeOpenApi() {
String paths[] = {"/store/**"};
return GroupedOpenApi.builder().group("stores").pathsToMatch(paths)
.build();
}
For the following Group definition (based on package name), the
OpenAPI description URL will be: /v3/api-docs/users
#Bean
public GroupedOpenApi userOpenApi() {
String packagesToscan[] = {"test.org.springdoc.api.app68.api.user"};
return GroupedOpenApi.builder().group("users").packagesToScan(packagesToscan)
.build();
}
For the following Group definition(based on path), the OpenAPI
description URL will be: /v3/api-docs/pets
#Bean
public GroupedOpenApi petOpenApi() {
String paths[] = {"/pet/**"};
return GroupedOpenApi.builder().group("pets").pathsToMatch(paths)
.build();
}
For the following Group definition (based on package name and path),
the OpenAPI description URL will be: /v3/api-docs/groups
#Bean
public GroupedOpenApi groupOpenApi() {
String paths[] = {"/v1/**"};
String packagesToscan[] = {"test.org.springdoc.api.app68.api.user", "test.org.springdoc.api.app68.api.store"};

In spring boot, GET request is returning 200 but POST request is returning 403

I've a spring boot application with springdoc-openapi-ui dependency, and without security.
The HTTP GET request is going through (status 200). But the HTTP POST request is not going through (status 403). What could be the reason for the 403 return code on the POST request?

Spring controller class
#RestController
public class TaController {
#RequestMapping(value = "/ping", method = RequestMethod.GET)
public #ResponseBody String pingGet() {
log.info("/ping");
return "ok";
}
#Operation(summary = "test")
#RequestMapping(value = "/test", method = RequestMethod.POST)
public String test(String string) {
log.info("/test");
return "ok !!";
}
swagger

RequestParam annotation is missing. Please use below method. You need to invoke POST method with request param key string
And ResponseBody annotation is also missing.
#Operation(summary = "test")
#RequestMapping(value = "/test", method = RequestMethod.POST)
public #ResponseBody String test(#RequestParam("string") String string) {
log.info("/test");
return "ok !!";
}

Either you have to use #RequestParam within your test method or you have to remove String string argument :
#RequestMapping(value = "/test", method = RequestMethod.POST)
public String test(#RequestParam(name= "string")String string) {
log.info("/test");
return "ok !!";
}

this works:
#Operation(summary = "test")
#PostMapping("/test")
public String test(#RequestBody String string) {
log.info("/test");
return "ok !!";
}
this will expect the string as a body.
please make sure you refresh the swagger interface after you apply the fix.
for header:
#Operation(summary = "test")
#PostMapping("/test")
public String test(#RequestHeader("someHeader") String string){
log.info("/test");
return "ok !!";
}
for path variable:
#Operation(summary = "test")
#PostMapping("/test/{somePath}")
public String test(#PathVariable("somePath") String string){
log.info("/test");
return "ok !!";
}

Jbehave Test configuration and test reporting not working as expected

I am using Jbehave to test some API's. I configured my stories but when i run the configuartion file, i get the following output:
Reports view generated with 0 stories (of which 0 pending) containing 0 scenarios (of which 0 pending)
I assumed that my configuration worked fine, and tried to run my whole test package, but it returned an output saying
No tests found in the package "com.example.prederiq.PrederaAiq"
However, when i ran my PrederaAiqApplicationTests.java file containing the test cases, all the tests passed but no console report or html report was returned to me. I have attached all the concerned files in my test package below and also the project structure below, please help me sort this out

Unable to consume JSON array using Spring RestTemplate

Am trying to populate a DTO from a published RESTful URL (simple HTTP GET) by using Spring's RestTemplate HTTP Client.
This is the content of the published JSON that I am trying to consume:
[{"startDate":"2017-01-29","cost":"$50000.00","id":1112,"name":"Porsche"},{"startDate":"2017-03-06","cost":"$27000.00","id":38626,"name":"BMW"}]
My DTO:
class DTO {
private String startDate;
private String cost;
private String name;
// Getters and Setters
}
My Response Object:
public class Response {
private static final STRING = "http://www.sample.com/product";
public static List<Object> getCampaigns() {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<Object[]> responseEntity = (ResponseEntity) restTemplate.getForEntity(URL, Object[].class);
Object[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();
return Arrays.asList(objects);
}
public void static main (String args []) {
List<Object> dtos = getCampaigns();
for (Object dto : dtos) {
System.out.println(dto.toString());
}
}
}
Here's my pom.xml:

When I run the main() method inside Response, I get the following exception:
00:24:14.191 [main] DEBUG org.springframework.web.client.RestTemplate - GET request for "http://www.sample.com/product" resulted in 200 (OK)
Exception in thread "main" org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [class [Ljava.lang.Object;] and content type [application/json;charset=utf-8]

at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:613)
at org.springframework.web.client.RestTemplate.getForEntity(RestTemplate.java:312)
What am I possibly doing wrong?

Try this
public class Response {
private static final String URL = "http://www.sample.com/product";
public static List<DTO> getCampaigns() {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<DTO[]> responseEntity = restTemplate.getForEntity(URL, DTO[].class);
DTO[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();
return Arrays.asList(objects);
}
public void static main (String args []) {
List<DTO> dtos = getCampaigns();
for (DTO dto : dtos) {
System.out.println(dto.toString());
}
}
}

use this jackson library instead

This is working and the message with higher priority is coming up. But it does not work with Spring-rabbit. Please find the code.

Now I am sending the message with different priority but it always receives the message in the order. Any suggestion will be great !!!

Just a guess here , i tried looking into an old AMQP library i had used (priority queue in an older version of Rabbit MQ).
The priority was set as below
args.put("x-max-priority", 10); , it looks slightly different from args.put("x-priority", 10);.
You could refer the old priority queue repo in the link. You could try to see if that helps

Queue must have arg 'x-max-priority'.
When publishing messageProperties.priority must be none 0.
When using spring-boot amqp, it is important to set
spring.rabbitmq.listener.simple.prefetch=1
Otherwise spring-boot is fetching 250 messages absolutely ignoring priorities.

If anyone has similar requirements on message priority then you need to define priority (Configuration Class) before the queue is created. If you plan to apply the config for existing queues it will not work (from my testing).
#Value("${myApp.rabbitmq.queue}")
private String queueName;
#Bean
Queue queue(){
Map<String, Object> args = new HashMap<String, Object>();
args.put("x-max-priority", 10);
Queue queue = new Queue(queueName, true, false, false, args) ;
return queue ;
}
When you push messages into the queue make sure the priority doesn't exceed 10 as we have defined max priority on the queue as 10.
