Quarkus: Fa'aonaponei Talosaga Fa'aaogā Helloworld e fai ma Fa'ata'ita'iga mai le JBoss EAP Quickstart (fa'aauau)

Talofa tagata uma - o le lona lima lea o pou i le matou Quarkus series! (I le ala, matamata i la matou webinar "O le Quarkus - Kubernetes native Java framework". Matou te faʻaali atu ia te oe pe faʻafefea ona amata mai le maoaʻe pe faʻafeiloaʻi fofo ua saunia)

В pou muamua na matou vaʻavaʻai i le faʻafouina o Java talosaga e faʻaaoga ai tekinolosi lagolago a Quarkus (CDI ma Servlet 3) faʻaaoga le polokalame helloworld mai le faleoloa e fai ma faʻataʻitaʻiga Red Hat JBoss Enterprise Application Platform (JBoss EAP) Amata vave. O le asō o le a tatou faʻaauauina le autu o le faʻafouina ma talanoaina le mataupu o le taumafaina manatua.

O le fuaina o galuega o le faavae autu lea o le toetoe lava o soʻo se faʻaleleia, ma o le faʻaaogaina o manatuaga o se vaega taua o le faʻagasologa o suʻesuʻega faʻatinoga. O le asō o le a tatou vaʻavaʻai i mea faigaluega fua talafeagai e mafai ona faʻaogaina e faʻatusatusa ai le faʻaleleia atili e ala i le faʻafouina o Java applications.

Mo nisi faʻamatalaga i le fuaina o le faʻaogaina o mafaufauga, vaʻai i le Quarkus tutorial ua faaulutalaina Fuaina o Galuega—E faapefea ona tatou fuaina le faaaogaina o manatua?

I lalo ifo o le a matou faʻaali atu ia te oe pe faʻapefea ona faʻatusatusa faʻamatalaga faʻaoga manatua mo ituaiga eseese o talosaga e tolu (JBoss EAP, JAR package, ma faʻaaogaina) e ala i le aoina o faʻamatalaga i luga o Linux e faʻaaoga ai le pmap ma ps utilities.

JBoss EAP

Matou te faʻalauiloaina se faʻataʻitaʻiga o le JBoss EAP talosaga (silasila i le vaega "Deploying helloworld" i pou muamua) ona suʻe lea o lona faagasologa PID (i la matou faʻataʻitaʻiga o le 7268) faʻaaoga le poloaiga lenei:

$ pgrep -lf jboss
7268 java

Manatua: O le -a filifiliga e mafai ai e oe ona aveese le laina atoa o le poloaiga (ie: $ pgrep -af jboss).

O lea ua matou faʻaogaina le PID 7268 i le ps ma le pmap poloaiga.

O iinei:

$ ps -o pid,rss,command -p 7268

Matou te faʻalauiloaina le talosaga JAR (silasila i le vaega "Run helloworld packaged in JAR" in pou muamua):

$ java -jar ./target/helloworld-<version>-runner.jar

Matou te toe vaʻavaʻai i le PID e faʻaaoga ai le pgrep command (o le taimi lea matou te faʻaogaina ai le -a filifiliga o loʻo faʻamatalaina i luga):

$ pgrep -af helloworld

Matou te tamoʻe le ps ma le pmap e fua ai le faʻaogaina o mafaufauga, ae o le taimi nei mo le faagasologa 6408.

Fa'atusatusa le fa'aaogaina o manatuaga

O lea la, matou te maua numera nei mo le faʻaaogaina o mafaufauga:

• JBoss EAP - 650 MB.

• Faʻatonu faila - 20 MB.

E manino lava, o le faila fa'atinoina e fa'aitiitia le manatua.

Sei o tatou otootoina pou 4 ma le 5

I lenei ma pou muamua, na matou vaʻavaʻai i le faʻafouina o Java talosaga e faʻaaoga ai tekinolosi e lagolagoina i Quarkus (CDI ma Servlet 3), faʻapea foʻi ma auala eseese e atiaʻe ai, fausia ma faʻatautaia ia talosaga. Na matou faʻaalia pe faʻafefea ona aoina faʻamatalaga faʻaoga manatua e iloilo ai faʻaleleia atili na ausia e se faʻaleleia. O nei tala e fesoasoani ia te oe e te malamalama ai pe faʻafefea ona galue Quarkus ma pe aisea e aoga ai-pe o e talanoa e uiga i le polokalama helloworld faigofie i a matou faʻataʻitaʻiga poʻo le sili atu ona lavelave mea moni o le olaga.

O le a matou toe foʻi mai i le lua vaiaso ma se faʻamatalaga mulimuli e uiga ia Quarkus - toe feiloaʻi!

I la matou pou mulimuli, o le a matou faʻaalia pe faʻafefea ona tuʻufaʻatasia le AMQ Online ma Quarkus e fausia ai se faiga faʻapipiʻi faʻaonaponei OpenShift e faʻaoga ai ni tekinolosi feʻau fou se lua. Faitau pea fesoʻotaʻiga.
