Spring: openAPI: Hide a rest api from documentation

By default all the rest apis are visible in swagger documentation. If you want to hide a rest API from swagger documentation, you can achieve this by @Hidden annotation.

 

Example

@Hidden
@Operation(summary = "about me", description = "Details about myself")
@GetMapping("/myself")
public ResponseEntity<Map<String, Object>> aboutMe() {

        Map<String, Object> result = new HashMap<>();

        return ResponseEntity.ok(result);

}

 

Find the below working application.

 

Step 1: Create new maven project ‘openapi-hide-an-api’.

 

Step 2: Update pom.xml with maven dependencies.

 

pom.xml

 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.sample.app</groupId>
        <artifactId>openapi-hide-an-api</artifactId>
        <version>1</version>

        <parent>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-parent</artifactId>
                <version>2.6.4</version>
        </parent>


        <properties>
                <java.version>1.8</java.version>
                <maven.compiler.source>${java.version}</maven.compiler.source>
                <maven.compiler.target>${java.version}</maven.compiler.target>
                <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
                <project.report.outputEncoding>UTF-8</project.report.outputEncoding>
        </properties>
        
        <dependencies>
                <dependency>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-starter-web</artifactId>
                </dependency>


                <dependency>
                        <groupId>org.springdoc</groupId>
                        <artifactId>springdoc-openapi-ui</artifactId>
                        <version>1.6.6</version>
                </dependency>


        </dependencies>
</project>

 

Step 3: Define UserController class.

 

UserController.java

 

package com.sample.app.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.v3.oas.annotations.Hidden;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.Parameter;
import io.swagger.v3.oas.annotations.enums.ParameterIn;
import io.swagger.v3.oas.annotations.media.Schema;

@RestController
@RequestMapping(value = "/api/v1/users")
@CrossOrigin("*")
public class UserController {

        @Operation(summary = "get users by city", description = "get users by city", parameters = {
                        @Parameter(name = "city", in = ParameterIn.PATH, description = "city ex: Bangalore", schema = @Schema(type = "string", allowableValues = {
                                        "Bangalore", "Chennai", "Hyderabad" })) })
        @GetMapping("/by-city/{city}")
        public ResponseEntity<Map<String, Object>> infoByCity(@PathVariable(name = "city") String city) {

                Map<String, Object> result = new HashMap<>();

                return ResponseEntity.ok(result);

        }

        @Hidden
        @Operation(summary = "about me", description = "Details about myself")
        @GetMapping("/myself")
        public ResponseEntity<Map<String, Object>> aboutMe() {

                Map<String, Object> result = new HashMap<>();

                return ResponseEntity.ok(result);

        }

}

 

Step 4: Define main application class.

 

App.java

 

package com.sample.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {
        public static void main(String[] args) {

                SpringApplication.run(App.class, args);

        }
}

 

Total project structure looks like below.

 

 

Run App.java.

 

Open the url ‘http://localhost:8080/swagger-ui/index.html’ to check swagger documentation.

 

 

From the above screen, you can confirm that the api ‘/api/v1/users/myself’ is hidden.
