Serialization hauv Java tso cai peb los hloov Cov Khoom Siv rau kwj uas peb tuaj yeem xa tawm hauv lub network lossis khaws cia ua ntaub ntawv lossis khaws cia hauv DB rau kev siv tom qab. Deserialization yog tus txheej txheem ntawm hloov cov khoom ntws mus rau qhov tseeb Java Object los siv rau hauv peb qhov kev pab cuam.
Dab tsi yog serialization thiab vim li cas nws thiaj siv?
Serialization yog txheej txheem ntawm kev hloov cov khoom mus rau hauv cov kwj ntawm bytes khaws cov khoom lossis xa mus rau lub cim xeeb, database, lossis cov ntaub ntawv. Nws lub hom phiaj tseem ceeb yog txuag lub xeev ntawm ib yam khoom kom thiaj li rov tsim tau nws thaum xav tau.
Thaum twg peb yuav tsum ua serialization?
Ntawm no yog qee qhov piv txwv ntawm kev siv serialization: - Storing cov ntaub ntawv nyob rau hauv ib tug object-oriented txoj kev rau cov ntaub ntawv ntawm disk, e.g. khaws cia ib daim ntawv teev cov khoom siv tub kawm ntawv. - Txuag cov kev pab cuam lub xeev ntawm disk, piv txwv li. txuag lub xeev ntawm kev ua si. - Xa cov ntaub ntawv hla lub network hauv daim ntawv khoom, piv txwv li. xa cov lus ua khoom hauv daim ntawv thov sib tham.
Kev siv cov txheej txheem serialization hauv Java yog dab tsi?
To serialize ib yam khoom txhais tau tias hloov nws lub xeev mus rau byte kwj komtus byte kwj tuaj yeem thim rov qab rau hauv ib daim qauv ntawm cov khoom. Ib yam khoom Java yog serializable yog tias nws cov chav kawm lossis ib qho ntawm nws cov superclasses siv los ntawm java. io ib. Serializable interface lossis nws cov subinterface, java.
Vim li cas thiaj xav tau serialization?
Zoo, serialization tso cai rau peb hloov lub xeev ntawm ib yam khoom mus rau hauv byte kwj, uas tom qab ntawd tuaj yeem khaws cia rau hauv cov ntaub ntawv hauv zos disk lossis xa tawm hauv lub network rau lwm lub tshuab. Thiab deserialization tso cai rau peb thim rov qab cov txheej txheem, uas txhais tau tias reconverting serialized byte kwj mus rau ib yam khoom dua.
