This example is very very similar to te previus one: I always have the web.xml file to confiure my web app, a file to configure the DispatcherServlet and a controller class that handle the HTTP Request. Alternatively, we can configure the application using Java configuration. However, XML is not the only way to configure spring application. In the previous Spring MVC 4 Hello World tutorial-XML example, we have developed a Hello world web application using XML configuration. One of them you can refer to is Setting Up Swagger 2 with a Spring REST API. Next to this example I have create a new Spring MVC Project by the related template project in STSEclipse. Spring Batch- Read a CSV file and write to an XML file. There are lots of articles on the web for annotation-based Swagger configuration. If you are using Spring Boot, then Swagger 2 configuration is very easy. For that, you can refer to the official Swagger core annotation page. Example: You can specify your REST APIs with Swagger specific annotation to provide better documentation to your services. To access your Swagger UI, you need to use the below URL: Now, during the deployment, Swagger will automatically find all the resources under the base package and generate the Swagger documentation. Once you are done with the above steps, then your application is configured with Swagger 2. Then declare this as the default servlet handler. Then declare the resource mapping for the Swagger UI HTML file and webjars as below.
SPRING MVC EXAMPLE PROJECT WITH ANNOTATION HOW TO
If you are not familiar with STS, I would recommend you to have a look at Spring MVC Tutorial where I have explained how to use it. Spring Tool Suite provides useful information about the aspects, so I would suggest you use it. Then declare the bean for Swagger 2 inside the same dispatcher servlet as below. All the above AOP annotations are defined in package. Note that whatever package you have specified here, the REST services available under this package only will be eligible for Swagger. Specify the base package for the component scan. Then, find out your MVC dispatcher servlet XML.
Below is the step-by-step guide to configuring Swagger 2 with Spring MVC using an XML-based configuration.įirst of all, add these below dependencies to your pom.xml. As the Spring configuration was done using XML based on the project, I had to go for that only, and I started looking for the example but could not find the proper article on the web immediately. We'll create a simple Foo API in Kotlin to see this in action.Īfter the initial setup, we'll add a data class and a controller.Recently, I got a requirement to integrate Swagger 2 with Spring MVC. Since we are using version 3.x of Spring Boot, SpringDoc supports applications written in Kotlin. Spring Boot 2.x has first-class support for Kotlin. Let's take a closer look at the parameters that we can configure for the plugin: We can also configure the plugin to use custom values: Let's see how we can configure the plugin in our pom.xml: To use this configuration it is enough to extend the FacesInitializer. The jsp pages are defined inside WEB-INF/jsp. Project Structure Here we have defined our config classes inside the package and all the static components inside webapp/ui. Similarly, in the Mojarra implementation there is a FacesInitializer class that configures the FacesServlet. Now let us develop a spring mvc annotation example based on the architecture defined above.
Maven runs the openapi plugin during the integration-test phase. The AnnotationConfigWebApplicationContext bootstraps the Spring'g context and adds the beans by registering the SpringCoreConfig class. The springdoc-openapi-maven-plugin plugin works with the spring-boot-maven plugin.
The springdoc-openapi library provides a Maven plugin, springdoc-openapi-maven-plugin, which generates OpenAPI descriptions in JSON and YAML formats.
