Microservices yog cov txheej txheem txhim kho software-ib qho txawv ntawm cov kev pabcuam-oriented architecture (SOA) architectural style uas tsim ib daim ntawv thov raws li kev sau ntawm cov kev pabcuam xoob xoob. Hauv ib microservices architecture, kev pab cuam yog nplua-grained thiab cov kev cai yog lub teeb yuag.
Ntawm no, Microservices hauv Java yog dab tsi?
Microservices yog ib daim ntawv ntawm kev pab cuam-taw qhia txog architecture style (ib qho ntawm cov txuj ci tseem ceeb tshaj plaws rau Java developers) nyob rau hauv cov ntawv thov raug tsim los ua ib qho ntawm cov kev pabcuam me me sib txawv es tsis yog ib qho app tag nrho.
Puas yog lub caij nplooj ntoos hlav khau raj yog Microservice moj khaum?
Caij nplooj ntoos hlav khau raj . Caij nplooj ntoos hlav khau raj yog qhov ua tau zoo lub moj khaum rau tsim ib Caij nplooj ntoos hlav - raws li kev thov. Caij nplooj ntoos hlav khau raj thiab Caij nplooj ntoos hlav Huab muab ntau yam cuab yeej built-in thiab lub moj khaum uas ua rau kev txhim kho huab-based microservice yooj yim. Feem ntau cov nta tuaj yeem qhib tau los ntawm tsuas yog siv ob peb cov lus piav qhia, yog li ua rau kev txhim kho nrawm heev
