MicroProfile Starter has generated this MicroProfile application for you.
The generation of the executable jar file can be performed by issuing the following command
mvn clean package
This will create an executable jar file experiments-microbundle.jar within the target maven folder. This can be started by executing the following command
java -jar target/experiments-microbundle.jar
To launch the test page, open your browser at the following URL
http://localhost:8080/index.html
(Really should write a decent readme here...)
This project was later updated to include content from the ModiTect OSS Quickstart archetype.
Run the following command to build this project:
mvn clean verify
Pass the -Dquick option to skip all non-essential plug-ins and create the output artifact as quickly as possible:
mvn clean verify -Dquick
Run the following command to format the source code and organize the imports as per the project's conventions:
mvn process-sources
This generated application is being extended as I learn more about MicroProfile.
The starter to this blog post series is available here.
By default, there is always the creation of a JAX-RS application class to define the path on which the JAX-RS endpoints are available.
Also, a simple Hello world endpoint is created, have a look at the class HelloController.
More information on MicroProfile can be found here
Configuration of your application parameters. Specification here
The example class ConfigTestController shows you how to inject a configuration parameter and how you can retrieve it programmatically.
Add resilient features to your applications like TimeOut, RetryPolicy, Fallback, bulkhead and circuit breaker. Specification here
The example class ResilienceController has an example of a FallBack mechanism where an fallback result is returned when the execution takes too long.
The health status can be used to determine if the 'computing node' needs to be discarded/restarted or not. Specification here
The class ServiceHealthCheck contains an example of a custom check which can be integrated to health status checks of the instance. The index page contains a link to the status data.
The Metrics exports Telemetric data in a uniform way of system and custom resources. Specification here
The example class MetricController contains an example how you can measure the execution time of a request. The index page also contains a link to the metric page (with all metric info)
Using the OpenId Connect JWT token to pass authentication and authorization information to the JAX-RS endpoint. Specification here
Have a look at the JWTClient class which calls the protected endpoint on the server from a Java Main method. The ProtectedController contains the protected endpoint since it contains the @RolesAllowed annotation on the JAX-RS endppoint method.
Exposes the information about your endpoints in the format of the OpenAPI v3 specification. Specification here
The index page contains a link to the OpenAPI information of your endpoints.
Allow the participation in distributed tracing of your requests through various micro services. Specification here
Example needs to be created.
A type safe invocation of HTTP rest endpoints. Specification here
Example needs to be created.
