Nyob zoo txhua tus ntawm qhov blog no, ntawm no yog plaub tshaj tawm hauv Quarkus series!
yog hais txog yuav ua li cas Quarkus muab MicroProfile thiab Caij nplooj ntoos hlav. Cia peb nco qab txog qhov ntawd yog positioned li "ultra-ceev subatomic Java", aka "Kubernetes-oriented Java pawg, tailored rau GraalVM thiab OpenJDK HotSpot thiab sib sau ua ke los ntawm cov tsev qiv ntawv zoo tshaj plaws thiab cov qauv." Niaj hnub no peb yuav qhia yuav ua li cas hloov kho cov ntawv thov Java uas twb muaj lawm siv lub peev xwm ntawm Quarkus, siv qhov piv txwv , uas siv CDI thiab Servlet 3 thev naus laus zis txhawb nqa los ntawm Quarkus.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov ntawm no tias ob qho tib si Quarkus thiab JBoss EAP hais txog kev siv cov cuab yeej ua raws li cov qauv raws li qhov ua tau. Tsis muaj daim ntawv thov khiav ntawm JBoss EAP? Tsis muaj teeb meem, nws tuaj yeem txav tau yooj yim los ntawm koj daim ntawv thov tam sim no rau JBoss EAP siv . Tom qab ntawd qhov kawg thiab ua haujlwm version ntawm cov txheej txheem niaj hnub yuav muaj nyob rau hauv qhov chaw cia khoom , nyob rau hauv lub module .
Thaum sau ntawv no peb siv , feem ntau thiab Building a .
Wb tau lub chaws
Ua ntej ntawm tag nrho cov, cia peb tsim ib lub zos clone ntawm lub repository :
$ git clone https://github.com/jboss-developer/jboss-eap-quickstarts.git

$ cd jboss-eap-quickstarts/helloworld/
Cia peb saib seb tus thawj helloworld ua haujlwm li cas
Qhov tseeb, cov ntsiab lus ntawm daim ntawv thov no yog qhov tseeb ntawm lub npe, tab sis peb yuav hloov kho nws cov cai nruj me ntsis kev tshawb fawb. Yog li ntawd, ua ntej, cia saib daim ntawv thov no hauv nws daim ntawv qub.
Deploying helloworld
1. Qhib lub davhlau ya nyob twg thiab mus rau hauv paus ntawm JBoss EAP nplaub tshev (koj tuaj yeem rub tawm nws ), uas yog, mus rau EAP_HOME folder.
2. Tua tawm JBoss EAP server nrog lub neej ntawd profile:
$ EAP_HOME/bin/standalone.sh
Nco ntsoov: Ntawm Windows, EAP_HOMEbinstandalone.bat tsab ntawv yog siv los tso nws.
Tom qab ob peb feeb, ib yam dab tsi zoo li no yuav tsum tshwm sim hauv lub cav:
[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. Qhib qhov browser :8080 and we see this:
Rice. 1. JBoss EAP Home Page.
4. Ua raws li cov lus qhia hauv phau ntawv qhia : nthuav helloworld thiab khiav (los ntawm qhov project hauv paus nplaub tshev) cov lus txib hauv qab no:
$ mvn clean install wildfly:deploy
Tom qab ua tiav cov lus txib no, peb yuav pom qee yam zoo li hauv qab no hauv lub cav:
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 8.224 s
Yog li, thawj qhov kev xa tawm ntawm daim ntawv thov helloworld ntawm JBoss EAP tsuas yog siv sijhawm li 8 vib nas this.
Testing helloworld
Ua nruj me ntsis raws li cov lus qhia , qhib hauv browser :8080/helloworld and we see this:
Rice. 2. Thawj Nyob Zoo Ntiaj Teb los ntawm JBoss EAP.
Kev hloov pauv
Hloov cov input parameter createHelloMessage(String name) los ntawm Ntiaj Teb rau Marco:
writer.println("<h1>" + helloService.createHelloMessage("Marco") + "</h1>");
Khiav cov lus txib nram qab no dua:
$ mvn clean install wildfly:deploy
Tom qab ntawd peb rov kho nplooj ntawv hauv browser thiab pom tias cov ntawv hloov pauv:
Rice. 3. Nyob zoo Marco hauv JBoss EAP.
Yob rov qab rau helloworld xa tawm thiab kaw JBoss EAP
Qhov no yog xaiv tau, tab sis yog tias koj xav rho tawm qhov kev xa tawm, koj tuaj yeem ua tau nrog cov lus txib hauv qab no:
$ mvn clean install wildfly:undeploy
Txhawm rau kaw koj qhov JBoss EAP piv txwv, tsuas yog nias Ctrl + C hauv lub qhov rais davhlau ya nyob twg.
Txhim kho helloworld
Tam sim no cia peb hloov kho tus thawj daim ntawv thov helloworld.
Tsim ib ceg tshiab
Peb tsim ib ceg ua hauj lwm tshiab tom qab lub Quickstart project tiav:
$ git checkout -b quarkus 7.2.0.GA
Hloov cov ntaub ntawv pom.xml
Peb yuav pib hloov daim ntawv thov los ntawm pom.xml cov ntaub ntawv. Txhawm rau tso cai rau Quarkus los ntxig XML blocks rau hauv nws, khiav cov lus txib hauv qab no hauv helloworld folder:
$ mvn io.quarkus:quarkus-maven-plugin:0.23.2:create
Thaum sau tsab xov xwm no, version 0.23.2 tau siv. Quarkus feem ntau tso tawm cov ntawv tshiab, koj tuaj yeem nrhiav seb qhov twg yog qhov tseeb ntawm lub vev xaib .
Cov lus txib saum toj no yuav ntxig cov ntsiab lus hauv qab no rau hauv pom.xml:
- Khoom , uas qhia txog lub version ntawm Quarkus siv.
- Thaiv kom import Quarkus BOM (daim nqi ntawm cov ntaub ntawv), thiaj li tsis mus ntxiv ib tug version rau txhua Quarkus dependency.
- Lub quarkus-maven-plugin yog lub luag haujlwm rau ntim cov ntawv thov thiab muab hom kev txhim kho.
- Cov haiv neeg profile rau tsim daim ntawv thov executables.
Ntxiv mus, peb manually hloov cov nram qab no rau pom.xml:
- Rub tawm tag los ntawm block thiab muab tso rau saum lub cim . Vim tias nyob rau hauv cov kauj ruam tom ntej peb yuav tshem tawm qhov thaiv , ces koj yuav tsum tau txuag .
- Tshem tawm ib qho thaiv , vim tias thaum khiav nrog Quarkus, daim ntawv thov no yuav tsis xav tau niam txiv pom los ntawm JBoss lawm.
- Ntxiv tag thiab muab tso rau hauv qab lub cim . Koj tuaj yeem qhia tus lej version koj xav tau.
- Tshem tag , txij li daim ntawv thov no tsis yog WAR, tab sis yog JAR li niaj zaus.
- Peb hloov kho cov kev vam meej hauv qab no:
- Hloov qhov kev vam meej javax.enterprise:cdi-api rau io.quarkus:quarkus-arc, tshem tawm muab , txij li (raws li cov ntaub ntawv) qhov no Quarkus txuas ntxiv muab kev txhaj tshuaj ntawm CDI kev vam meej.
- Hloov qhov kev vam meej org.jboss.spec.javax.servlet:jboss-servlet-api_4.0_spec rau io.quarkus:quarkus-undertow, tshem tawm muab , vim hais tias (raws li cov ntaub ntawv) qhov no Quarkus txuas ntxiv muab kev txhawb nqa rau servlets.
- Peb tshem tawm org.jboss.spec.javax.annotation:jboss-annotations-api_1.3_spec kev vam khom vim nws los nrog cov kev vam khom peb nyuam qhuav hloov.
Lub version ntawm cov ntaub ntawv pom.xml nrog tag nrho cov kev hloov pauv nyob ntawm .
Nco ntsoov tias mvn io.quarkus:quarkus-maven-plugin: 0.23.2: tsim cov lus txib saum toj no tsis tsuas yog hloov cov ntaub ntawv pom.xml, tab sis kuj ntxiv ntau cov khoom rau qhov project, uas yog cov ntaub ntawv hauv qab no thiab folders:
- Cov ntaub ntawv mvnw thiab mvnw.cmd thiab .mvn nplaub tshev: Maven Wrapper tso cai rau koj los khiav Maven tej yaam num ntawm ib tug muab Maven version yam tsis tau txhim kho qhov version.
- Docker folder (hauv src/main/ directory): Qhov no muaj piv txwv Dockerfiles rau haiv neeg thiab jvm hom (nrog rau cov ntaub ntawv .dockerignore).
- Cov ntaub ntawv khaws cia (hauv src/main/ directory): Qhov no muaj cov ntaub ntawv khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Tua tawm helloworld
Txhawm rau kuaj daim ntawv thov, peb siv quarkus: dev, uas tso tawm Quarkus hauv hom kev txhim kho (kom paub meej ntxiv, saib tshooj no hauv phau ntawv qhia ).
Nco ntsoov: Cov kauj ruam no yuav cia siab tias yuav ua rau muaj qhov yuam kev, txij li peb tseem tsis tau hloov pauv txhua qhov tsim nyog.
Tam sim no cia peb khiav cov lus txib kom pom nws ua haujlwm li cas:

Yog li, nws tsis ua haujlwm ... Vim li cas?
Lub UnsatisfiedResolutionException taw qhia rau chav HelloService, uas yog ib tug tswv cuab ntawm HelloWorldServlet chav kawm (java member: org.jboss.as.quickstarts.helloworld.HelloWorldServlet#helloService). Qhov teeb meem yog tias HelloWorldServlet xav tau qhov kev txhaj tshuaj ntawm HelloService, thiab nws nrhiav tsis tau (txawm tias ob chav kawm no nyob hauv tib pob).
Nws yog lub sijhawm rov qab los thiab nyeem nws ua haujlwm li cas hauv Quarkus , thiab yog li ntawd (CDI). Yog li ntawd, qhib Cov Lus Qhia thiab Kev Cia Siab Kev Txhaum Cai thiab hauv ntu peb nyeem: "Ib chav kawm taum uas tsis muaj cov lus piav qhia taum txhais tsis tau tshawb nrhiav."
Cia peb saib ntawm HelloService chav kawm - nws yeej tsis muaj cov lus piav qhia zoo li no. Yog li ntawd, nws yuav tsum tau ntxiv kom Quarkus tuaj yeem tshawb nrhiav thiab pom taum. Thiab txij li qhov no yog cov khoom tsis muaj lub xeev, peb tuaj yeem yooj yim ntxiv @ApplicationScoped annotation zoo li no:
@ApplicationScoped
public class HelloService {
Nco ntsoov: ntawm no qhov chaw loj hlob tuaj yeem hais kom koj ntxiv cov pob uas xav tau (saib kab hauv qab), thiab koj yuav tau ua qhov no manually, zoo li qhov no:
import javax.enterprise.context.ApplicationScoped;
Yog tias koj tsis ntseeg txog qhov twg yuav tsum tau siv nyob rau hauv rooj plaub thaum nws tsis tau teev tseg rau lub hauv paus taum txhua, nyeem cov ntaub ntawv .
