Talofa tagata uma i luga o lenei blog, o le fa'ailoga lona fa i le Quarkus series!
e uiga i le auala e tuʻufaʻatasia ai e Quarkus le MicroProfile ma le Spring. Sei matou faamanatu atu lena mea o loʻo faʻatulagaina e pei o le "ultra-fast subatomic Java", ae o le "Kubernetes-oriented Java stack, faʻatulagaina mo GraalVM ma OpenJDK HotSpot ma faʻapotopoto mai faletusi sili ma tulaga masani." I aso nei o le a tatou faʻaalia pe faʻafefea ona faʻaonaponei faʻaoga Java o loʻo i ai nei e faʻaaoga ai le gafatia o Quarkus, faʻaaoga le faʻataʻitaʻiga , lea e fa'aogaina ai le CDI ma le Servlet 3 tekonolosi e lagolagoina e Quarkus.
E taua le maitauina iinei o Quarkus ma JBoss EAP o loʻo faʻamamafaina le faʻaaogaina o meafaigaluega e faʻatatau i tulaga faʻavae pe a mafai. E leai se talosaga e fa'aoga ile JBoss EAP? Leai se faʻafitauli, e mafai ona faigofie ona faimalaga mai lau 'auʻaunaga o loʻo iai nei ile JBoss EAP faʻaaoga . A mae'a, o le a maua le fa'amaumauga mulimuli ma le galue o le code fa'aonaponei i totonu o le fale teu oloa , i totonu o le module .
A o tusia lenei pou sa matou faʻaaogaina , tele ma le Fale a .
Tatou maua le code
Muamua, se'i o tatou faia se clone i le lotoifale o le fale teu oloa :
$ git clone https://github.com/jboss-developer/jboss-eap-quickstarts.git

$ cd jboss-eap-quickstarts/helloworld/
Se'i o tatou va'ai pe fa'apefea ona galue le helloworld muamua
O le mea moni, o le aano o lenei talosaga e manino mai le igoa, ae o le a matou faʻafouina lona tulafono faʻasaienisi. O le mea lea, muamua, seʻi o tatou vaʻavaʻai i lenei talosaga i lona tulaga muamua.
Fa'aogaina helloworld
1. Tatala se laina ma alu i le aʻa o le faila JBoss EAP (e mafai ona e sii maia ), o lona uiga, i le faila EAP_HOME.
2. Fa'alauiloa le JBoss EAP server fa'atasi ai ma le fa'ailoga fa'aletonu:
$ EAP_HOME/bin/standalone.sh
Manatua: I luga o Windows, o le EAP_HOMEbinstandalone.bat tusitusiga e faʻaaoga e faʻalauiloa ai.
A maeʻa ni nai sekone, e tatau ona aliali mai se mea faʻapenei i totonu o le ogalaau:
[org.jboss.as] (Controller Boot Thread) WFLYSRV0025: JBoss EAP 7.2.0.GA (WildFly Core 6.0.11.Final-redhat-00001) started in 3315ms - Started 306 of 527 services (321 services are lazy, passive or on-demand)
3. Tatala i se su'esu'ega :8080 ma matou vaʻai i le mea lenei:
Alaisa. 1. JBoss EAP Itulau Aiga.
4. Mulimuli i faatonuga i le tusi lesona : faʻalautele le helloworld ma tamoe (mai le faila aʻa o le poloketi) le poloaiga lenei:
$ mvn clean install wildfly:deploy
A maeʻa le faʻatinoina o lenei poloaiga, o le a tatou vaʻai i se mea e pei o loʻo i lalo i le ogalaau:

O lea la, o le faʻapipiʻiina muamua o le helloworld application ile JBoss EAP na ova atu ile 8 sekone.
Su'ega helloworld
Faia sa'o e tusa ai ma faatonuga , tatala i le browser :8080/helloworld ma matou va'ai i le mea lenei:
Alaisa. 2. Original Hello World mai le JBoss EAP.
Faia o suiga
Suia le fa'ailoga fa'aoga createHelloMessage(Igoa fa'aigoa) mai le Lalolagi i Marco:
writer.println("<h1>" + helloService.createHelloMessage("Marco") + "</h1>");
Toe fai le poloaiga lenei:
$ mvn clean install wildfly:deploy
Ona matou faʻafouina lea o le itulau i le suʻega ma vaʻai ua suia le tusitusiga:
Alaisa. 3. Talofa Marco i le JBoss EAP.
Toe foʻi i tua le faʻaogaina o le helloworld ma tapuni le JBoss EAP
Ole filifiliga lea, ae afai e te manaʻo e faʻamalo le faʻapipiʻiina, e mafai ona e faia i le poloaiga lenei:
$ mvn clean install wildfly:undeploy
Ina ia tapunia lau faʻataʻitaʻiga JBoss EAP, naʻo le oomi Ctrl + C i le faʻamalama faʻamalama.
Fa'aleleia helloworld
Ia tatou fa'aonaponei le ulua'i talosaga helloworld.
Fausia se lala fou
Matou te fatuina se lala faigaluega fou pe a maeʻa le poloketi amata vave:
$ git checkout -b quarkus 7.2.0.GA
Suia le faila pom.xml
O le a amata ona matou suia le talosaga mai le faila pom.xml. Ina ia faʻatagaina Quarkus e faʻapipiʻi poloka XML i totonu, faʻataʻitaʻi le poloaiga lenei i le helloworld folder:
$ mvn io.quarkus:quarkus-maven-plugin:0.23.2:create
A'o tusia lenei tusiga, sa fa'aogaina le version 0.23.2. E masani ona faʻasalalau e Quarkus ni faʻamatalaga fou, e mafai ona e suʻeina poʻo fea faʻamatalaga e sili ona lata mai i luga o le upega tafaʻilagi .
O le faʻatonuga o loʻo i luga o le a faʻaofiina elemene nei i le pom.xml:
- Meatotino , o loʻo faʻamaonia ai le faʻasologa o Quarkus e faʻaaoga.
- Poloka e fa'aulufale mai Quarkus BOM (pepa o meafaitino), ina ia le fa'aopoopoina se fa'amatalaga mo fa'amoemoega ta'itasi a Quarkus.
- O le quarkus-maven-plugin e nafa ma le afifiina o le talosaga ma le tuʻuina atu o le atinaʻe.
- Le talaaga fa'ale-aganu'u mo le fatuina o mea e mafai ona fa'atinoina.
E le gata i lea, matou te faia ma le lima suiga nei i le pom.xml:
- Toso ese le pine mai le poloka ma tuu i luga o le pine . Aua o le isi laasaga o le a tatou aveese le poloka , ona tatau lea ona e sefe .
- Aveese se poloka , aua a tamoʻe ma Quarkus, o lenei talosaga o le a le toe manaʻomia se matua pom mai le JBoss.
- Fa'aopoopo se fa'ailoga ma tuu i lalo o le pine . E mafai ona e faʻamaonia le numera o le faʻasologa e te manaʻo ai.
- Aveese le pine , talu ai o lenei talosaga e le o toe avea ma WAR, ae o se JAR masani.
- Matou te suia fa'alagolago nei:
- Suia le fa'alagolago javax.enterprise:cdi-api ile io.quarkus:quarkus-arc, aveese saunia , talu ai (e tusa ai ma le docs) o lenei faʻaopoopoga Quarkus e tuʻuina atu ai le tui o CDI faʻalagolago.
- Suia le fa'alagolago org.jboss.spec.javax.servlet:jboss-servlet-api_4.0_spec ile io.quarkus:quarkus-undertow, aveese saunia , aua (e tusa ai ma le docs) o lenei faʻaopoopoga Quarkus e maua ai le lagolago mo servlets.
- Matou te aveese le fa'alagolago org.jboss.spec.javax.annotation:jboss-annotations-api_1.3_spec talu ai e sau ma fa'alagolago na matou suia.
O lo'o iai le fa'asologa o le faila pom.xml ma suiga uma i .
Manatua o le mvn io.quarkus:quarkus-maven-plugin:0.23.2:faia le poloaiga i luga e le gata e suia ai le faila pom.xml, ae faʻaopoopoina foi se numera o vaega i le poloketi, e pei o faila ma faila nei:
- O le faila mvnw ma le mvnw.cmd ma le faila .mvn: Maven Wrapper e mafai ai ona e faʻatautaia galuega faatino a Maven o se Maven version e aunoa ma le faʻapipiʻiina o lena lomiga.

O lea, e le aoga ... Aisea?
O le UnsatisfiedResolutionException e faasino i le vasega HelloService, o se sui o le vasega HelloWorldServlet (tagata java: org.jboss.as.quickstarts.helloworld.HelloWorldServlet#helloService). O le faʻafitauli o le HelloWorldServlet e manaʻomia se injected instance of HelloService, ma e le mafai ona maua (e ui lava o nei vasega e lua o loʻo i totonu o le afifi e tasi).
Ua oo i le taimi e toe foi ai i ma faitau pe faapefea ona galue i Quarkus , ma o lea (CDI). O lea, tatala le Contexts and Dependency Injection guide ma i le vaega tatou te faitau ai: “O se vasega o fatu pi e leai se faʻamatalaga e faʻamalamalama ai pi e leʻo suʻeina."
Sei o tatou tilotilo i le vasega HelloService - e matua leai lava se faʻamatalaga faapena. O le mea lea, e tatau ona faʻaopoopo ina ia mafai e Quarkus ona suʻe ma maua le pi. Ma talu ai o lenei mea o se mea e leai se mea, e faigofie ona tatou faʻaopoopo le @ApplicationScoped faʻamatalaga pei o lenei:
@ApplicationScoped
public class HelloService {
Manatua: O iinei e mafai e le siosiomaga atinaʻe ona fai atu ia te oe e faʻaopoopo le afifi manaʻomia (silasila i le laina i lalo), ma e tatau ona e faia ma le lima, pei o lenei:
import javax.enterprise.context.ApplicationScoped;
Afai o loʻo e masalosalo pe o le a le lautele e tatau ona faʻaogaina i le tulaga pe a le o faʻamaonia mo le puna puna, faitau le faʻamaumauga .
O lea ua matou toe taumafai e faʻalauiloa le talosaga ma le poloaiga ./mvnw compile quarkus: dev:

public class HelloWorldServlet extends HttpServlet {
O le mea lea, matou te o atu i le browser i :8080/HelloWorld ma matou va'ai i mea nei:
Alaisa. 5: Le itulau o le Quarkus dev mo le talosaga Talofa World.
Ia, e aoga mea uma.
Sei o tatou faia suiga i le code. Manatua o le ./mvnw compile quarkus:dev poloaiga o loʻo faʻaauau pea ma e leai so matou faʻamoemoe e taofi. Sei o tatou taumafai e faʻaoga tutusa - e matua le taua lava - suiga i le code lava ia ma vaʻai pe faʻafefea ona faʻafaigofie e Quarkus le olaga mo le tagata atiaʻe:
writer.println("<h1>" + helloService.createHelloMessage("Marco") + "</h1>");
Faasaoina le faila ona toe faʻafouina lea o le itulau web e vaʻai Hello Marco, e pei ona faʻaalia i le faʻamalama i lalo:
Alaisa. 6. Talofa Marco itulau i Quarkus dev.
Sei o tatou siaki le gaioiga i le laina:

Fausia helloworld i totonu o se pusa JAR
O lea la ua galue le code e pei ona tatau ai, seʻi o tatou afifiina i le poloaiga lenei:
$ ./mvnw clean package
O lenei poloaiga e fausia ai faila JAR e lua i totonu o le /target folder: le helloworld-.jar file, o se mea masani masani na tuufaatasia e le Maven team faatasi ai ma vasega ma punaoa a le poloketi. Ma le faila helloworld-runner.jar, o se JAR e mafai ona faʻatinoina.
Faamolemole ia matau e le o se uber-jar, talu ai o faʻalagolago uma e naʻo le kopiina i totonu o le /target/lib folder (e le o afifiina i se faila JAR). O le mea lea, ina ia mafai ona faʻatautaia lenei JAR mai se isi faila poʻo luga o se isi talimalo, e tatau ona e kopi uma le JAR faila lava ia ma le / lib faila iina, ona o le Vasega-Ala elemene i le MANIFEST.MF faila i le pusa JAR o loʻo i ai. se lisi manino o JARs mai lib folders
Ina ia aʻoaʻo pe faʻafefea ona fai talosaga uber-jar, faʻamolemole vaʻai i le aʻoaʻoga .
Tatala helloworld afifi i le JAR
Ole taimi nei e mafai ona tatou faʻatautaia la tatou JAR e faʻaaoga ai le tulafono java masani:
