This article is accompanied by a working code example on GitHub. This article will explore these ways and will also provide some pointers on when a given way might be preferable over another. Spring Boot offers more than one way of doing it. Your application will work the same, but now whenever you make a change in your source code or resources, you can trigger the updates.Handling exceptions is an important part of building a robust application.
SPRING BOOT ANNOTATIONS LIST UPDATE
Under Modify options, set both the On 'Update' action and On frame deactivation options to Update classes and resources and click OK to apply the changes. In the Dependencies tool window, find and add the Spring Boot Developer Tools dependency: :spring-boot-devtoolsĪlternatively, you can add the dependency manually:įrom the main menu, select Run | Edit Configurations and select the SpringBootTutorialApplication configuration. This functionality is based on the spring-boot-devtools module.įrom the main menu, select Code | Generate Alt+Insert and then select Add dependency…. You can also update static and template resources in a running application. This can save time in a large project with a lot of dependencies, especially for debugging and tweaking your code. IntelliJ IDEA provides a way to restart just your Spring application context without having to also restart all the external library contexts.
When you make a change in your code, you need to rerun the whole project: shut down the application with all its dependencies, rebuild the code, start the application with the new code.

To see the endpoints that are actually declared in your code, use the Endpoints tool window ( View | Tool Windows | Endpoints). This Actuator tab in the Run tool window shows the endpoints available at runtime, not necessarily all request mappings declared in your code. Click the endpoint path to run the corresponding request directly, generate and open it in an HTTP request file to modify and execute when you need it, or open the endpoint URL in a web browser if it's a GET request. Open the Mappings tab to interact with request mapping endpoints.īy default, it shows all endpoints, including those provided by libraries, such as the Spring Boot Actuator itself. Open the Health tab to monitor the status of your application. Restart your Spring application with or Ctrl+F5 and open the Actuator tab in the Run tool window. In the request file, compose the following POST request:Ĭlick in the popup or press Ctrl+Shift+O to load the updated project structure. Open DemoController.java and click in the gutter next to the addCustomer() method. IntelliJ IDEA has an HTTP client built into the editor to compose and execute HTTP requests. To add customers, you need to send a POST request to the /add endpoint with request parameters that specify the first and last name. Open a web browser and go to You should see your application respond with an empty list because you don't have any customers in the database. By default, the built-in Apache Tomcat server is listening on port 8080. The Console tab shows the output of Spring log messages. Press Shift+F10 or use the icon in the gutter of the SpringBootTutorialApplication.java file to run your application.īy default, IntelliJ IDEA shows your running Spring Boot application in the Run tool window. Run your application and execute requests IntelliJ IDEA designates the web request methods with in the gutter, which you can click to execute the corresponding request.
The annotation maps the value in place of the id variable from the URL to the corresponding method parameter. Public void setFirstName(String firstName). Import class Customer = GenerationType.AUTO)
:spring-boot-starter-data-jpaĪlternatively, you can add these dependencies to pom.xml manually: In the Dependencies tool window, find and add the necessary Maven dependencies: With the pom.xml file open in the editor, from the main menu, select Code | Generate Alt+Insert and then select Add dependency…. Open the pom.xml file in your project root directory. H2 is a fast in-memory SQL database written in Java. The Spring Data JPA module provides support for data access using the Java Persistence API (JPA). Run your application and execute HTTP requestsĪdd Spring Boot Actuator for advanced health monitoring and endpoint analysisĪdd Spring Boot Developer Tools for faster application updates This tutorial guides you through steps that cover the following:Īdd dependencies for JPA and H2 that enable your Spring application to store and retrieve relational data It should already have the Spring Boot Starter Web dependency for building web applications. The tutorial assumes that you start with a simple Spring Boot Maven project generated with Spring Initializr. This tutorial expands on Tutorial: Create your first Spring application to show how IntelliJ IDEA can help you write code, analyze your Spring application, and manage it at runtime.
