Nws muaj cov kab uas ua haujlwm tos kom ua tiav. Peb ua tau siv ThreadPoolExecutor los tsim thread pas dej ua ke Java . Java xov pas dej ua ke tswj kev sau ntawm Runnable threads. Cov neeg ua haujlwm threads ua haujlwm Runnable threads los ntawm cov kab.
Kuj nug, ThreadPoolExecutor ua haujlwm li cas hauv Java?
ThreadPoolExecutor yog ib qho kev siv ntawm ExecutorService interface. Cov ThreadPoolExecutor executes lub luag hauj lwm muab (Callable los yog Runnable) siv ib tug ntawm nws internally pooled threads. Lub pas dej ua ke muaj nyob rau hauv lub ThreadPoolExecutor tuaj yeem muaj ntau qhov sib txawv ntawm cov xov.
Tsis tas li ntawd, dab tsi yog lub pas dej ua ke thiab vim li cas nws thiaj siv? A xov pas yog ib pawg neeg ua haujlwm xov uas ua tau zoo asynchronous callbacks sawv cev ntawm daim ntawv thov. Cov xov pas yog qhov tseem ceeb siv kom txo tus naj npawb ntawm daim ntawv thov xov thiab muab kev tswj hwm tus neeg ua haujlwm xov.
Ib yam li ntawd, kev siv ExecutorService hauv Java yog dab tsi?
Cov Java ExecutorService yog ib qho kev tsim uas tso cai rau koj dhau ib txoj haujlwm kom ua tiav los ntawm cov xov asynchronously. Cov kev pabcuam executor tsim thiab tswj xyuas lub pas dej ua ke ntawm cov xov rov qab rau kev ua tiav cov haujlwm xa tawm.
Dab tsi yog tus neeg ua haujlwm xov hauv Java?
siv ib txhij xov pas dej ua ke, uas muaj cov neeg ua haujlwm xov . Hom no xov muaj cais los ntawm Runnable thiab Callable cov haujlwm nws ua thiab feem ntau siv los ua ntau yam haujlwm. Cov neeg ua haujlwm xov yog li qub xov tab sis lawv muaj nyob nyias los ntawm Runnable lossis Callable chav kawm uas lawv ua haujlwm rau.

Dab tsi yog kev siv cov ntawv cim kev cai li cas koj nkag mus rau hauv Apex cov chav kawm thiab hauv Visualforce nplooj ntawv?
Cov ntawv sau kev cai tso cai rau cov neeg tsim khoom tsim cov ntawv thov ntau hom lus los ntawm kev nthuav qhia cov ntaub ntawv (piv txwv li, pab cov ntawv lossis cov lus yuam kev) hauv tus neeg siv hom lus. Cov ntawv sau kev cai yog cov ntawv sau muaj txiaj ntsig uas tuaj yeem nkag tau los ntawm Apex cov chav kawm, nplooj ntawv Visualforce, lossis cov khoom siv xob laim
Dab tsi yog qhov tseem ceeb ntawm kev siv kev coj ncaj ncees rau cov ntaub ntawv kev ruaj ntseg?
Rau cov kws tshaj lij kev ruaj ntseg cov ntaub ntawv, muaj ob lub hom phiaj tseem ceeb thaum nws los txog rau cov ntaub ntawv tseem ceeb: tiv thaiv nws thiab paub txog nws qhov chaw. Cov koom haum tsis tuaj yeem xav tias cov ntaub ntawv raug cai lossis tau txais los ntawm kev coj ncaj ncees
