Typically, we face this issue in a microservices environment. Most of us end up managing a separate Swagger-UI for each application, which means that each service will have its own endpoint and to access the Swagger-UI and we have to use a different URL for different applications. 3 | 4 | # Solution 5 | - Get the list of registered service instances from the service registry. 6 | - For each registered service instance, pull the Swagger definition JSON from the instance and store it locally. In our case, we are putting this JSON in the in-memory documentation context backed by a concurrent map. 7 | - Refresh the in-memory context at regular intervals to automatically remove/add the definitions as they are updated in the service registry. 8 | - Provide a single endpoint to serve Swagger definitions from our in-memory store on the basis of service instance name. 9 | 10 | ## This repositry contain below projects 11 | 12 | * **central-docs-eureka-server:** Service registry powered by Netflix Eureka 13 | * **employee-application** and **person-application:** REST applications with Swagger-UI enabled. You can follow [this article] (https://dzone.com/articles/monitoring-using-spring-boot-2-prometheus-amp-graf) for a step-by-step guide. 14 | * **documentation-service:** Spring Boot-based REST application consolidating all the Swagger JSON and offering it in a single endpoint. Please note that this component can be part of a gateway or the registry itself, but I have chosen to keep it separate. The final documentation shall be available at http://localhost:9093/swagger-ui.html. 15 | 16 | 17 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # microservice-patterns 2 | Code to share the knowledge I gained while designing and implementing micro services 3 | Below are the projects description 4 | 1.

[centralized-swagger-docs](https://github.com/hellosatish/microservice-patterns/tree/master/centralized-swagger-docs) : Swagger is un-doubtly the most used REST api documentation framework. And [swagger-ui](https://github.com/swagger-api/swagger-ui) is the implementation for Java. 6 | But, in case of microservices where you have multiple application and each exposes swagger document. This project is aimed at how do you consolidate all these swagger documents and expose them at one place. 7 | The [documentation-app](https://github.com/hellosatish/microservice-patterns/tree/master/centralized-swagger-docs/documentation-app) aggregates data(swagger docs JSON) from other services and exposes a single endpoint for outer world. This application could be ocnsidered as the implemenation of Aggregator microservice pattern. 8 | 9 | >Please note this implementation is specific to swagger-api and spring boot. However you can implement the same design in any language and tool 10 | 11 | 12 | 3.

You can use below command to create the topic 'gplsLocation' 9 | `kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic gpslocation` 10 | 11 | ## Project 12 | ### vehicle-tracker: 13 | The overall project wrapping all other applications as Modules. 14 | 15 | ### common-libs: 16 | this will contain the POJO classes to model the different objects like Vehicle, VehicleCount, VehicleLocation. This application will be added as dependency to other two applications eliminating the concerns of model mismatch. 17 | ### vehicle-simulator: 18 | the responsibility of this application will be to simulate the behavior of GPS signals being emitted by the device fitted in each vehicle. 19 | ### tracker-dashboard: 20 | this application will be our stream processing component. Though we can have separate application for querying the state-stores of Kafka, but for the sake of simplicity we add this functionality in this application itself. 21 | 22 | ## How to run the application 23 | 24 | 1. start the zookeper server 25 | 2. start the kafka server 26 | 3. create topic 'gpslocation', if not already created 27 | 4. start the *vehicle-simulator* application and use below CURL command to simulate the GPS signal emission 28 | ` curl -X POST "http://localhost:8080/simulate/3/{emit-interval}/{stop-index}?emitInterval=1&stopIndex=1" -H "accept: */*" ` 29 | 5. start the *tracker-dashboard* application and use below CURL command to get the Online/Offline vehicle count 30 | ` curl http://localhost:9090/count/Online` 31 | ` curl http://localhost:9090/count/Offline` 32 | -------------------------------------------------------------------------------- /idor-prevention/src/main/java/org/sk/owasp/api/security/idor/web/resources/SampleAPI.java: -------------------------------------------------------------------------------- 1 | package org.sk.owasp.api.security.idor.web.resources; 2 | 3 | import java.util.List; 4 | import java.util.stream.Collectors; 5 | 6 | import org.sk.owasp.api.security.idor.db.mock.DataBaseService; 7 | import org.sk.owasp.api.security.idor.util.IdorUtility; 8 | import org.springframework.util.MimeTypeUtils; 9 | import org.springframework.web.bind.annotation.GetMapping; 10 | import org.springframework.web.bind.annotation.PathVariable; 11 | import org.springframework.web.bind.annotation.RestController; 12 | 13 | import lombok.RequiredArgsConstructor; 14 | 15 | /** 16 | * FOR DEMONSTRATION ONLY, NOT TO BE USED IN PRODUCTION.

So we are not implmenting some of the features that you will consider while writing code for production. 18 | * some of which are as follows 19 | *
    20 | *
  1. We are not adding any validation. This can be implemented using Validator
    2. 21 | *
  2. No adding error handlers. Which can be done using {@link JavalinValidation#validate()}
    3. 22 | *
  3. Each of the method could be packaged as separate handler and then can be used as reference
    4. 23 | *
  4. Some other points that are supported by Javalin and you may consider
    5. 24 | *
