Deploying the Spring Boot application

To deploy the Spring Boot application, you need to have knowledge of MVN and Tomcat servlets. MVN will be used for building the Web Application Resource or the Web Application Archive (WAR) file, and Apache Tomcat is our application server. Let's see how we can install the Spring Boot application in the application servers:

# Download Tomcat 9.0.13 latest version using below commands:

PacktPub$ curl -O http://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.13/bin/apache-tomcat-9.0.13.tar.gz
 % Total % Received % Xferd Average Speed Time Time Time Current
 Dload Upload Total Spent Left Speed
100 9112k 100 9112k 0 0 799k 0 0:00:11 0:00:11 --:--:-- 1348k

# Extract it and provide sufficient permissions.

$ tar -xvzf apache-tomcat-9.0.13.tar.gz

# Maven clean and package everything into a WAR file.

$ mvn clean package

# Copy WAR created by MVN to Tomcat/webapp, we are renaming WAR to springbootcode.war

$ cp target/PacktPub-spring-boot-example.war apache-tomcat-9.0.13/webapps/springbootcode.war

# Start Tomcat like below

$ ./apache-tomcat-9.0.13/bin/startup.sh
