Deploying with an Embedded Web Server5:50 with Chris Ramacciotti
This video demonstrates the quickest deployment method, and that is to use Gradle to run the `bootRun` task, which comes from the Gradle 'spring-boot' plugin.
Configuring the Embedded Server
When launching a Spring Boot application as a standalone app with an embedded web server, such as Tomcat or Jetty, you can configure various properties, like changing the port or enabling SSL.
Below is an example of enabling SSL on a specified port using a self-signed certificate.
Note that in production, you'd want to have a certificate signed by a third-party so that users don't get browser warnings.
To generate a self-signed certificate, you can use the JDK's
keytool utility as follows:
keytool -genkey -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650
This will ask you a handful of questions, and upon finishing will generate a file named keystore.p12. Move this file to src/main/resources/keystore.p12.
Then, in application.properties, add the following properties:
server.port: 8443 server.ssl.key-store: classpath:keystore.p12 server.ssl.key-store-password: PASSWORD_USED_WITH_KEYTOOL server.ssl.keyStoreType: PKCS12 server.ssl.keyAlias: tomcat
Now, when you run the app with
./gradlew bootRun, you can visit https://localhost:8443 and see your app served via HTTPS. You'll likely see a browser warning since you're using a self-signed certificate, but if you accept the warning, you'll be able to proceed.
