  • Resource group: xxxxxxxx-rg
  • Region: eastus
  • Name: example; javawebap
  • Runtime: Java
  • App Service Plan: free, basic, premium

Create Spring Boot application:

• Create spring boot application https://start.spring.io/ using Maven
• Add REST controller
• Add the following Maven pluggin in the pom.xml:

    <plugin> 
      <groupId>com.microsoft.azure</groupId>  
      <artifactId>azure-webapp-maven-plugin</artifactId>  
      <version>2.9.0</version>  
      <configuration>
        <subscriptionId>111111-11111-11111-1111111</subscriptionId>
        <resourceGroup>xxxxxxxx-rg</resourceGroup>
        <appName>javawebap</appName>
        <pricingTier>B1</pricingTier>
        <region>eastus</region>
        <runtime>
          <os>Linux</os>      
          <webContainer>Java SE</webContainer>
          <javaVersion>Java 11</javaVersion>
        </runtime>
        <deployment>
          <resources>
            <resource>
              <type>jar</type>
              <directory>${project.basedir}/target</directory>
              <includes>
