1. Supersonic Subatomic Java Framework Quarkus Kumar Pallav
2. About Me Kumar Pallav 10 Years of experience with Java , Spring and Microservices based framework kumar_pallav Spring Boot and Microservices : https://bit.ly/spring-ms RxJava : http://bit.ly/rx_java2 codingsaint kp@codingsaint.com
3. About Quarkus Creating a project using quarkus maven plugin Adding dependencies using maven Plugin Connecting to Mongo DB and performing CRUD operation Hibernate Panache Building Native Images Today's talk
4. About Quarkus Supersonic Subatmoic Framework Quarkus is a full-stack, Kubernetes-native Java framework made for Java virtual machines (JVMs) and native compilation, optimizing Java specifically for containers and enabling it to become an effective platform for serverless, cloud, and Kubernetes environments
5. JDK 1.8+ Maven 3.6.X GraalVM Docker Softwares required and installed for this session https://bit.ly/Quarkus_demo
6. mvn io.quarkus:quarkus-maven-plugin:1.2.0.Final:create \ -DprojectGroupId=com.codingsaint.learning.quarkus \ -DprojectArtifactId=user-service \ -DclassName="com.codingsaint.learning.quarkus.UserResource" \ -Dpath="/user" Creating a project using quarkus maven plugin
7. Adding dependencies using maven Plugin mvn quarkus:add-extension -Dextensions=hibernate-validator,mongodb- panache,resteasy-jsonb
8. Run Demo as developer's joy mvn quarkus:dev
9. Build a native image mvn package -Pnative
10. Build a native image mvn package -Pnative -Dnative-image.docker-build=true
11. connect to database quarkus.mongodb.connection-string = mongodb://localhost:27017 quarkus.mongodb.database=todo-users
12. Creating User Entity With Hibernate Panache @MongoEntity public class User extends PanacheMongoEntity { private String userId; @NotNull(message = "First Name is required") private String firstName; private String lastName; @BsonProperty("dob") @NotNull(message = "Date of Birth is required") private LocalDate dateOfBirth; @NotNull(message = "Email is required") private String email; private Boolean active; }
13. Hibernate Panache custom Method public static User findByUserId(String userId) { return find("userId", userId).firstResult(); }
14. UserResource class @Path("/users") public class UserResource { @GET @Produces(MediaType.APPLICATION_JSON) public Response users() { return Response.ok(User.listAll()).build(); } }
15. UserResource Add to Mongo @POST@ Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response users(final @Valid User user) { user.setUserId(UUID.randomUUID().toString()); user.setActive(true); User.persist(user); return Response.ok().build(); }
16. UserResource Update Mongo @PUT @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response update(final @Valid User user) { user.update(); return Response.ok(user).build(); }
17. UserResource Using Custom method @GET @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) @Path("id/{id}") public Response getUserByUserId(@PathParam("id") String userId) { User user = User.findByUserId(userId); return Response.ok(user).build(); }
18. UserResource delete a user @DELETE @Path("id/{id}") public Response deleteUser(@PathParam("id") String userId) { User.delete("userId",userId); return Response.noContent().build(); }
