SpringBoot Hot Deployment Configuration

In this article, we will explore the configuration required for hot deployment of SpringBoot applications in IDEA. Hot deployment allows for automatic recompilation and redeployment of applications without requiring manual intervention.

IDEA Configuration

To enable hot deployment in IDEA, we need to configure the project settings to automatically build and recompile the project. This can be achieved by following these steps:

  1. Open the Settings dialog box by pressing Ctrl + Shift + A and searching for “Registry.”
  2. In the Registry window, navigate to “Build, Execution, Deployment” > “Compiler.”
  3. Check the box next to “Build project automatically” to enable automatic building of the project.

SpringBoot Maven Configuration

To enable hot deployment in SpringBoot, we need to configure the Maven project to use the spring-boot-devtools dependency. This can be achieved by adding the following dependency to the pom.xml file:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <optional>true</optional>
</dependency>

Additionally, we need to configure the Maven build plug-in to enable hot deployment. This can be achieved by adding the following configuration to the pom.xml file:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <fork>true</fork>
    </configuration>
</plugin>

Configuring Fork

It is essential to configure the fork option to true in the Maven build plug-in configuration. This will enable hot deployment and allow for automatic recompilation and redeployment of the application.

Hot Deployment in Action

Once the configuration is complete, any changes made to the Java file or configuration file will automatically trigger a restart of the application. Note that Chrome browser cache may need to be closed and F12 pressed to refresh the page.

Conclusion

In this article, we have explored the configuration required for hot deployment of SpringBoot applications in IDEA. By following these steps, developers can enable hot deployment and enjoy the benefits of automatic recompilation and redeployment of their applications.
