Deploying Webflux application Jar file

Question

I have created Graphql application with Spring Boot Webflux. I am pretty new to this. Can some one please tell me the process of deployment of same. I know about traditional tomcat deployment but i read that using that, it removes of the features.

Answer 1

There are two ways you could deploy a spring-boot application.

• Running as a standalone JAR file
• Deploy as a WAR file into a tomcat (For Spring WebFlux application this is not supported).

Deploy as a standalone JAR

To generate an executable JAR we could either use spring-boot maven plugin or spring-boot gradle plugin depending on your use case.

Spring Boot Maven Plugin

• Add following to the pom.xml.

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

• Run following command to generate the executable.

mvn clean package spring-boot:repackage

• Then run the generated JAR file with following command.

java -jar <path-to-generated-jar>/<app-name>.jar

Spring Boot Gradle Plugin

• Run following command to generate the executable.

./gradlew bootJar

• Then run the generated JAR file with following command.

java -jar <path-to-generated-jar>/<app-name>.jar
