Na Maachị XNUMXth, RedHat (n'oge na-adịghị anya IBM) usoro ọhụrụ - . Dịka ndị nrụpụta si kwuo, usoro a dabere na GraalVM na OpenJDK HotSpot ma emebere ya maka Kubernetes. Nchịkọta Quarkus gụnyere: JPA/Hibernate, JAX-RS/RESTEasy, Eclipse Vert.x, Netty, Apache Camel, Kafka, Prometheus na ndị ọzọ.
Ebumnuche bụ ime Java ka ọ bụrụ isi ikpo okwu maka ntinye Kubernetes na mmepe ngwa na-enweghị ihe nkesa, na-enye ndị mmepe ụzọ dị n'otu maka mmepe na ụdị mmeghachi omume na nke dị mkpa.

Hello developer!Rịba ama na Quarkus na-eji nkọwa ọkọlọtọ sitere na usoro ndị ama ama - CDI na JAX-RS. Ọ dịghị mkpa ịmụta ihe ọhụrụ ma ọ bụrụ na ị na-arụ ọrụ na CDI na JAX-RS na mbụ, n'ezie.
Na-arụ ọrụ na nchekwa data
A na-eji nkọwa nkọwa Hibernate na ọkọlọtọ JPA maka ụlọ ọrụ. Dịka ọ dị na ndị njikwa REST, ịkwesịrị ide opekempe koodu. O zuru ezu igosi ihe ndabere na faịlụ mgbakọ, tinye nkọwa @Entity ma hazie datasource na ngwa.properties.
Ha niile. Enweghị ụlọ ọrụ sessions, persistence.xml ma ọ bụ faịlụ ọrụ ndị ọzọ. Anyị na-ede naanị koodu achọrọ. Agbanyeghị, ọ bụrụ na ọ dị mkpa, ịnwere ike ịmepụta faịlụ persistence.xml wee hazie oyi akwa ORM nke ọma.
Quarkus na-akwado caching nke ụlọ ọrụ, nchịkọta maka otu-na-ọtụtụ mmekọrịta, yana ajụjụ. Na ilele mbụ ọ dị mma, mana ọ dị mpaghara caching, maka otu ọnụ ụzọ Kubernetes. Ndị ahụ. A naghị emekọrịta cache nke ọnụ ọnụ dị iche iche na ibe ha. Enwere m olileanya na nke a bụ nwa oge.
Mkpebi koodu asynchronous
Dịka ekwuru n'elu, Quarkus na-akwadokwa ụdị mmemme na-emeghachi omume. Enwere ike dee koodu nke ngwa gara aga n'ụdị dị iche.

Ngwa akọwapụtara nke ikpo okwu
Ebe ọ bụ na ejikọtara Quarkus na GraalVM nke ọma, ọ ga-ekwe omume ịmepụta koodu akọwapụtara nke ọma. Iji mee nke a, ịkwesịrị ịwụnye GraalVM wee kọwapụta mgbanwe gburugburu GRAALVM_HOME. Ọzọkwa ma kọwaa ya mgbe ị na-ewu ngwa:

Enwere ike iji usoro Quarkus na Maven na Gradle. A kwadoro Maven nke ọma, n'adịghị ka Gradle. Ọ dị nwute, ugbu a Gradle anaghị akwado ịmepụta ọrụ efu; enwere ozi zuru ezu na webụsaịtị .
