[Java] Deploy the Spring Boot application to Azure App Service
Purpose
Deploy the Spring Boot web app to Azure App Service.
Prerequisites
Deploy what you created as a Spring starter project in Eclipse + Gradle.
Creating an App Service
-Match the Tomcat and Java versions with the web application.
-If the OS is Windows, it is convenient because the App Service Editor can be used.
Creating a War file
Create a Deployable War File https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file
Create a deployable war file according to the above procedure.
Make the class with @SpringBootApplication inheritSpringBootServletInitializer.
Also, add the war plugin to build.gradle and set Tomcat to providedRuntime.
build.gradle
apply plugin: 'war'
dependencies {
//Don't include tomcat in war
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
}
Execute the'bootWar' task and create a war file.
Put the WAR file on Azure
Easy with the App Service Editor. App Service Editor is a tool that allows you to directly edit files on App Service with a GUI like Visual Studio Code. It can be used only when the OS of App Service is Windows.
If there is already a ROOT folder, delete it.
Drag and drop the created WAR file to the Explorer part of the App Service Editor and upload it.
You can also upload by right-clicking in the upload destination folder or in the margin of Explorer → "Upload File". After waiting for a while, the WAR file will be expanded.
