Kia ora koutou katoa – koinei te pou tuarima o ta tatou raupapa Quarkus! (Na te ara, tirohia to maatau paetukutuku . Ma matou e whakaatu ki a koe me pehea te tiimata mai i te wahanga ka whakawhiti ranei i nga otinga kua oti te hanga)
В I titiro matou ki te whakahou i nga tono Java ma te whakamahi i nga hangarau tautoko a Quarkus (CDI me Servlet 3) ma te whakamahi i te kaupapa helloworld mai i te putunga hei tauira. . I tenei ra ka haere tonu te kaupapa o te whakahoutanga me te matapaki i te take o te kohi mahara.
Ko te inenga mahi te putake o te nuinga o nga whakahoutanga, a ko te purongo mo te whakamahinga mahara tetahi waahanga nui o te mahi tātari mahi. I tenei ra ka titiro tatou ki nga taputapu ine e tika ana ka taea te whakamahi hei tatau i nga whakapainga kua tutuki ma te whakahou i nga tono Java.
Mo etahi atu korero mo te ine i te whakamahinga mahara, tirohia te akoranga Quarkus kua taitarahia
Kei raro nei ka whakaatu noa me pehea te whakataurite i nga raraunga whakamahi mahara i waenga i nga momo tono rereke e toru (JBoss EAP, JAR package, me te kawe) ma te kohikohi i enei raraunga i runga i te Linux ma te whakamahi i nga taputapu pmap me te ps.
JBoss EAP
Ka whakarewahia e matou he tauira o te tono JBoss EAP (tirohia te waahanga "Te tuku helloworld" kei roto ) ka titiro ake i tana tukanga PID (i roto i ta maatau tauira ko 7268) ma te whakamahi i te whakahau e whai ake nei:
$ pgrep -lf jboss
7268 java
Tuhipoka. Ko te whiringa -a ka taea e koe te tango i te rarangi whakahau katoa (ara: $ pgrep -af jboss).
Inaianei kei te whakamahi matou i te PID 7268 i roto i nga whakahau ps me te pmap.
Anei:
$ ps -o pid,rss,command -p 7268

Ka titiro matou ki te uara RSS ka kite kei te pau te 650 MB o te mahara a JBoss EAP.
kete JAR
Ka whakarewahia e matou te tono JAR (tirohia te waahanga "Run helloworld packaged in JAR" in ):
$ java -jar ./target/helloworld-<version>-runner.jar
Ka titiro ano matou ki te PID ma te whakamahi i te whakahau pgrep (i tenei wa ka whakamahia e matou te -a waahanga kua whakaahuahia i runga ake nei):
$ pgrep -af helloworld
6408 java -jar ./target/helloworld-<version>-runner.jar
Ka whakahaerehia e matou te ps me te pmap hei ine i te whakamahinga mahara, engari inaianei mo te tukanga 6408.
Anei:
$ ps -o pid,rss,command -p 6408

Kōnae kawe
Ka whakarewahia e matou te mea taketake (tirohia te waahanga "Te whakahaere i te konae kawe helloworld maori" kei roto ):
$ ./target/helloworld-<version>-runner
Me titiro ano ki tana PID:
$ pgrep -af helloworld
6948 ./target/helloworld-<version>-runner
Na ka whakamahia e matou te ID tukanga hua (6948) i roto i nga whakahau ps me te pmap.

Ka titiro matou ki te RSS ka kite kei te 20 MB te mahara o te konae kawe.
Te whakataurite i te kohi mahara
Na, i whiwhi matou i nga nama e whai ake nei mo te whakamahi mahara:
- JBoss EAP - 650 MB.
- Mōkihi JAR – 130 MB.
- Kōnae Ka taea te whakahaere - 20 MB.
Maamaa, ka iti ake te mahara o te konae kawe.
Kia whakarāpopotohia ngā pou 4 me te 5
I tenei me nga panui o mua, i titiro matou ki te whakahou i nga tono Java ma te whakamahi i nga hangarau e tautokohia ana i Quarkus (CDI me Servlet 3), tae atu ki nga momo huarahi ki te whakawhanake, ki te hanga me te whakahaere i aua tono. I whakaatu matou me pehea te kohikohi raraunga whakamahi mahara ki te arotake i nga whakapainga kua tutuki i taua whakamohoatanga. Ka awhina enei tuhinga ki a koe kia mohio koe ki te mahi a Quarkus me te aha i whai hua ai—ahakoa kei te korero koe mo te kaupapa helloworld ngawari i roto i o maatau tauira, he tino uaua ake ranei nga tono mo te ao.
Ka hoki mai matou i roto i nga wiki e rua me te panui whakamutunga mo Quarkus - ka kite koe i reira!
I roto i ta maatau panui whakamutunga, ka whakaatu maatau me pehea te whakakotahi i te AMQ Online me Quarkus ki te hanga i tetahi punaha korero a OpenShift hou ma te whakamahi i nga hangarau korero hou e rua. Pānuihia .
