Quarkus: Kugadzirisa Zvishandiso Uchishandisa Helloworld seMuenzaniso kubva kuJBoss EAP Quickstart (inoenderera)

Mhoroi mose - iyi ndiyo yechishanu positi muQuarkus yedu nhevedzano! (Nenzira, tarisa webinar yedu "Iyi iQuarkus - Kubernetes yekuzvarwa Java chimiro". Isu tinokuratidza maitiro ekutanga kubva pakatanga kana kutamisa akagadzirira-akagadzirwa mhinduro)

В yapfuura post takatarisa kugadzirisa maapplication eJava tichishandisa Quarkus-inotsigirwa tekinoroji (CDI neServlet 3) tichishandisa iyo helloworld chirongwa kubva kune repository semuenzaniso. Red Hat JBoss Enterprise Application Platform (JBoss EAP) Quickstart. Nhasi tichaenderera mberi nenyaya yemazuva ano uye kukurukura nyaya yekushandiswa kwendangariro.

Kuyera kwekuita ndiyo hwaro hwakakosha hwehumwe kusimudzira, uye ndangariro dzekushandisa kushuma chikamu chakakosha chemaitiro ekuongorora maitiro. Nhasi tichatarisa maturusi ekuyera akakodzera ayo anogona kushandiswa kuyera kuvandudzwa kunoitwa nekuvandudza maapplication eJava.

Kuti uwane rumwe ruzivo nezve kuyera kushandiswa kwendangariro, ona Quarkus Tutorial ine musoro Kuyera Kuita—Tinoyera sei kushandiswa kwendangariro?

Pazasi isu tinongokuratidza nzira yekuenzanisa ndangariro yekushandisa data kune matatu akasiyana marudzi ekushandisa (JBoss EAP, JAR package, uye inoitiswa) nekuunganidza iyo data paLinux uchishandisa pmap uye ps zvinoshandiswa.

JBoss EAP

Isu tinotangisa muenzaniso weJBoss EAP application (ona chikamu "Kuendesa helloworld" mukati yapfuura post) wobva watarisa maitiro ayo PID (mumuenzaniso wedu ndeye 7268) uchishandisa murairo unotevera:

$ pgrep -lf jboss
7268 java

Cherechedza: Iyo -a sarudzo inobvumidza iwe kuburitsa iyo yakazara yekuraira mutsara (kureva: $ pgrep -af jboss).

Iye zvino isu tinoshandisa PID 7268 mune ps uye pmap mirairo.
