Java World Knowledge Sharing Portal: Swager UI for SpringBoot

Swagger UI is a collection of HTML, Javascript, and CSS assets that dynamically generate beautiful documentation from an OAS-compliant API. This means if we have an Springboot application with the help of plug and play method we can create the documentation of our Spring boot application as show below.

For more details you can visit to the below url

https://swagger.io/tools/swagger-ui/

Please follow the below steps religiously

1- Create a springboot project with just springweb as dependecies using spring starter. I am using STS ide.
2- Add following dependencies in the pom.xml

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
            <scope>compile</scope>
        </dependency>

3- SimpleSpringbootSwaggerApplication

package com.siddhu;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class SimpleSpringbootSwaggerApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(SimpleSpringbootSwaggerApplication.class, args);
    }
 
     
 
}

4- SwaggerConfig

package com.siddhu.config;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket productApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .build();
              
    }
     
}

5- IndexController

package com.siddhu.controller;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
import com.siddhu.model.Employee;
 
import io.swagger.annotations.Api;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@RestController
public class IndexController {
    @GetMapping("/getEmployee")
    public String getEmployee() {
        Employee objEmployee =  new Employee("1","Siddhu");
        return "getEmployee called" + objEmployee.toString();
    }
 
 
    @PostMapping("/insertEmployee/{id}/{name}")
    public String insertEmployee(@PathVariable("id") String id ,@PathVariable("name") String name) {
        Employee objEmployee =  new Employee(id,name);
        System.out.println("insertEmployee called for id"+ objEmployee.getId() +"for name:" + objEmployee.getName());
        return "insertEmployee called" + objEmployee.toString();
 
    }
 
    @PutMapping("/updateEmployee/{id}/{name}")
    public String updateEmployee(@PathVariable("id") String id ,@PathVariable("name") String name) {
        Employee objEmployee =  new Employee(id,name);
        System.out.println("updateEmployee called for id"+ objEmployee.getId() +"for name:" + objEmployee.getName());   
        return "updateEmployee called" + objEmployee.toString();
 
    }
 
    @DeleteMapping("/deleteEmployee/{id}")
    public String deleteEmployee(@PathVariable("id") String id) {
        Employee objEmployee =  new Employee(id);
        System.out.println("deleteEmployee called for id"+ objEmployee.getId()+"for name:" + objEmployee.getName());
        return "deleteEmployee called" + objEmployee.toString();
 
    }
}

6- Employee

package com.siddhu.model;
 
public class Employee {
    public String id;
    public String name;
 
 
    public Employee() { 
    }
 
    public Employee(String id) { 
        this.id = id;   
        this.name= "default";
    }
     
    public Employee(String id, String name) { 
        this.id = id;
        this.name= name; 
    }
 
 
    @Override
    public String toString() {
        return "Employee [id=" + id + ", name=" + name  + "]";
    }
 
 
    public String getId() {
        return id;
    }
 
 
    public void setId(String id) {
        this.id = id;
    }
 
 
    public String getName() {
        return name;
    }
 
 
    public void setName(String name) {
        this.name = name;
    }
 
 
 
 
}

Make sure to compile the project usign maven clean install and run the application

Once the application is running make sure that we get response from our getEmployee url

Now use below url to get the swagger-ui.html

http://localhost:8080/swagger-ui.html

On clicking on below url we will get our project OpenAPI 3 specific yaml or JSON files.

http://localhost:8080/v2/api-docs

If you want you can also get the yaml file. I used online converter to convert it to yaml

https://www.json2yaml.com/

Now lets see our swagger-ui.html url

Hit on all the options and check click on Try it out

Now lets chanage few of the code for more beautification of our documentation

Note: You can get this code from below url
https://github.com/shdhumale/simple-springboot-swagger.git

Generally we use to have the swagger running only for our Dev and Testing environment and not for our Production.

This can be easily achieved by just adding one annotation in our config files as shown below

@Profile(“!production”)

package com.siddhu.config;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
 
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@Configuration
@EnableSwagger2
@Profile("!production")
public class SwaggerConfig {
    @Bean
    public Docket productApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
                .select()
                .build();
              
    }
    private ApiInfo apiInfo()
    {
        return new ApiInfoBuilder().title("This is title for siddhu swagger example").description("This is siddhu description swagger example").version("1.1").build();
    }
     
}
