Running the service

There are many ways to run the service.

Right-click on the project and select Run As | Maven build and configure the Run Configurations to execute the spring-boot:run target as follows:

On clicking Run, if the internet connection and configuration are fine, you will see the following console output:

Note the stages of the Maven execution:

1. First, the Maven task compiles all the Java files. We have three simple Java classes as of now.
2. The next step runs it as an application, where a Tomcat instance starts.
3. Note the mapping of the URLs /product/ and /productIds to the Bean methods.
4. Tomcat listens on port 8080 for service requests.

You can also run the service by just right-clicking the class that has the main method (ProductSpringApp) in Package Explorer and then selecting Run As | Java Application.
