Aloha kākou - ʻo kēia ka lima o ka pou ma kā mākou Quarkus series! (Ma ke ala, e nānā i kā mākou webinar . E hōʻike mākou iā ʻoe pehea e hoʻomaka ai mai ka ʻohi ʻana a i ʻole e hoʻololi i nā hoʻonā i hana ʻia)
В ua nānā mākou i ka hoʻololi ʻana i nā noi Java me ka hoʻohana ʻana i nā ʻenehana kākoʻo Quarkus (CDI a me Servlet 3) me ka hoʻohana ʻana i ka laʻana o ka papahana helloworld mai ka waihona. . I kēia lā e hoʻomau mākou i ke kumuhana o ka modernization a kūkākūkā i ka pilikia o ka hoʻohana hoʻomanaʻo.
ʻO ke ana hana ke kumu kumu o ka hoʻonui ʻana, a ʻo ka hōʻike ʻana i ka hoʻohana ʻana i ka hoʻomanaʻo he ʻāpana koʻikoʻi o ke kaʻina hana loiloi hana. I kēia lā, e nānā mākou i nā mea ana e pili ana i hiki ke hoʻohana ʻia no ka helu ʻana i nā hoʻomaikaʻi i loaʻa ma ka hoʻololi ʻana i nā noi Java.
No ka ʻike hou aku e pili ana i ke ana ʻana i ka hoʻohana ʻana i ka hoʻomanaʻo, e ʻike i ke kumu aʻo Quarkus i kapa ʻia
Ma lalo nei e hōʻike wale mākou pehea e hoʻohālikelike ai i ka ʻikepili hoʻohana hoʻomanaʻo ma waena o ʻekolu mau ʻano noi like ʻole (JBoss EAP, JAR package, a me executable) ma o ka hōʻiliʻili ʻana i kēia ʻikepili ma Linux me ka hoʻohana ʻana i nā pono pmap a me ps.
JBoss EAP
Hoʻomaka mākou i kahi hiʻohiʻona o ka noi JBoss EAP (e ʻike i ka ʻāpana "Deploying helloworld" ma ) a laila e nānā i kāna kaʻina hana PID (ma kā mākou hiʻohiʻona ʻo 7268) me ka hoʻohana ʻana i kēia kauoha:
$ pgrep -lf jboss
7268 java
Nānā: ʻO ke koho -a hiki iā ʻoe ke unuhi i ka laina kauoha piha (ʻo ia hoʻi: $ pgrep -af jboss).
I kēia manawa, hoʻohana mākou i ka PID 7268 i nā kauoha ps a me pmap.

Hoʻohālikelike i ka hoʻohana ʻana i ka hoʻomanaʻo
No laila, loaʻa iā mākou nā helu aʻe no ka hoʻohana ʻana i ka hoʻomanaʻo:

- ʻO ka pūʻolo JAR - 130 MB.

ʻIke loa, ʻoi aku ka liʻiliʻi o ka waihona hoʻokō.
E hōʻuluʻulu kākou i nā pou 4 a me 5
Ma kēia a me nā pou mua, ua nānā mākou i ka hoʻololi ʻana i nā polokalamu Java me ka hoʻohana ʻana i nā ʻenehana i kākoʻo ʻia ma Quarkus (CDI a me Servlet 3), a me nā ʻano like ʻole e hoʻomohala, kūkulu a holo i ia mau noi. Ua hōʻike mākou pehea e hōʻiliʻili ai i ka ʻikepili hoʻohana hoʻomanaʻo e loiloi i nā hoʻomaikaʻi i hoʻokō ʻia e ia hoʻonui. Kōkua kēia mau ʻatikala iā ʻoe e hoʻomaopopo i ka hana ʻana o Quarkus a me ke kumu e pono ai, inā ʻoe e kamaʻilio e pili ana i ka papahana helloworld maʻalahi i kā mākou mau hiʻohiʻona a i ʻole nā pololei ola maoli paʻakikī.
E hoʻi mākou i loko o ʻelua pule me kahi pou hope e pili ana iā Quarkus - e ʻike iā ʻoe ma laila!
Ma kā mākou pou hope, e hōʻike mākou pehea e hoʻohui ai i ka AMQ Online a me Quarkus e kūkulu i kahi ʻōnaehana memo OpenShift hou me ka hoʻohana ʻana i ʻelua ʻenehana leka uila. Heluhelu mai .
