Mayelana nalolu hlelo lokusebenza

Ingabe ufuna ukufunda i-Hibernate, ithuluzi elinamandla nelisetshenziswa kabanzi le-Java ORM? Ungabheki kude kunohlelo lokusebenza lwe-Hibernate Tutorial Android! Uhlelo lwethu lokusebenza lumahhala 100% futhi aludingi ukubhalisa, okukuvumela ukuthi ugxumele emhlabeni we-Hibernate kalula.

Kulesi sifundo esibanzi, sihlanganisa konke odinga ukukwazi nge-Hibernate. Siqala ngesinyathelo soku-1, sikwethulela i-Hibernate ne-ORM (Object-Relational Mapping) futhi sichaza izinzuzo zokusebenzisa i-Hibernate kumaphrojekthi akho e-Java.

Okulandelayo, esinyathelweni sesi-2, siyakuqondisa ngenqubo yokumisa i-Hibernate. Lesi sinyathelo sibalulekile ekuqinisekiseni ukuthi i-Hibernate isethwe ngendlela efanele futhi ilungele ukusetshenziswa kuphrojekthi yakho.

Isinyathelo sesi-3 sigxile ekusethweni kwamafayela e-Hibernate Mapping, ikufundisa ukuthi ungabeka kanjani imephu amakilasi akho e-Java kumathebula esizindalwazi usebenzisa i-Hibernate. Uzofunda ukuthi ungachaza kanjani amamephu, ukhiqize amathebula, futhi ulungise ubudlelwano phakathi kwamathebula.

Esinyathelweni sesi-4, singena e-States of Objects e-Hibernate, sichaza izifundazwe ezihlukene into engaba kuzo lapho isebenza ne-Hibernate. Ukuqonda lezi zifundazwe kubalulekile ukuze usebenzise ngempumelelo i-Hibernate kumaphrojekthi akho.

Isinyathelo sesi-5 sihlanganisa Ukusebenza Ngezinto Eziqhubekayo ku-Hibernate. Uzofunda ukudala, ukuvuselela, ukususa, nokuthola izinto usebenzisa i-Hibernate.

Esinyathelweni sesi-6 kuye ku-11, sihlanganisa Izindlela Eziyi-11 Zokufihla, okuhlanganisa ukulondoloza, ukuvuselela, ukususa, ukulayisha, ukuthola, ukuhlanganisa, ukuphikelela, ukulondolozaOrUpdate, ukukhipha, ukushaywa, nokusula. Lezi zindlela ziwumgogodla we-Hibernate futhi ukuqonda ukuthi zisetshenziswa kanjani ngempumelelo kubalulekile ekuthuthukisweni okuphumelelayo kwe-Hibernate.

Isinyathelo sesi-7 sihlanganisa Izinhlobo Zokwenza Imephu e-Hibernate, okuhlanganisa nokukodwa kuya kokukodwa, okukodwa kuya kokuningi, okuningi kuya kokukodwa, kanye nokuningi kokukodwa kuya kokuningi. Uzofunda ukuthi ungasebenzisa kanjani lezi zinhlobo zemephu ukuchaza ubudlelwano phakathi kwamathebula esizindalwazi kumaphrojekthi akho e-Hibernate.

Isinyathelo sesi-8 sigxile Kulimi Lombuzo Lwe-Hibernate (HQL), olukuvumela ukuthi ubhale imibuzo ku-Hibernate usebenzisa i-syntax efana ne-SQL. Uzofunda ukuthi ungayibhala kanjani imibuzo eyisisekelo nethuthukile usebenzisa i-HQL.

Esinyathelweni sesi-9, sihlanganisa Imibuzo Yemibandela, ekuvumela ukuthi wakhe imibuzo eguquguqukayo usebenzisa i-Hibernate. Uzofunda ukuthi ungasebenzisa kanjani Imibuzo Yemibandela ukuze ubuyise izinto kusizindalwazi ngokusekelwe kumibandela ethile.

Okokugcina, ku-Isinyathelo se-10, simboza Ukugcinwa Kwesikhashana ku-Hibernate, okukuvumela ukuthi ugcine idatha kumemori ukuze uthuthukise ukusebenza. Uzofunda ukuthi ungamisa kanjani i-caching ku-Hibernate futhi uyisebenzise ngempumelelo kumaphrojekthi akho.

Sengiphetha, uhlelo lokusebenza lwe-Hibernate Tutorial Android iyithuluzi eliphelele lanoma ubani ofuna ukufunda i-Hibernate ngokushesha futhi kalula. Ngesifundo sethu esibanzi, uzofunda konke odinga ukukwazi nge-Hibernate nokuthi ungayisebenzisa kanjani ngempumelelo kumaphrojekthi akho e-Java. Landa uhlelo lwethu lokusebenza namuhla futhi uqale ukufunda i-Hibernate!
