Jackson yog tsis tu ncua sai dua GSON thiab JSONSmart. Boon JSON parser thiab tus tshiab Groovy 2.3 JSON parser sai dua Jackson . Lawv nrawm dua nrog InputStream, Reader, nyeem cov ntaub ntawv, byte, thiab char thiab String.
Dhau li ntawd, qhov txawv ntawm Jackson thiab GSON yog dab tsi?
Google cov GSON (https://github.com/google/ gson ). GSON yog lub tsev qiv ntawv Java uas hloov Java Objects rau hauv JSON thiab rov ua dua. Jackson yog ib pawg ntawm cov cuab yeej ua cov ntaub ntawv tseem ceeb los ntawm nws cov streaming JSON parser thiab generator tsev qiv ntawv. Tsim los rau Java, nws tuaj yeem ua lwm yam tsis yog JSON encodings.
Ib sab saum toj no, lub tsev qiv ntawv Java JSON twg yog qhov zoo tshaj? Jackson yog lub tsev qiv ntawv Java ntau lub hom phiaj rau kev ua JSON cov ntaub ntawv hom. Jackson lub hom phiaj yog qhov ua tau zoo tshaj plaws ua ke ntawm nrawm, raug, hnav, thiab ergonomic rau cov neeg tsim khoom. Yog tias koj tsuas yog xav hloov Java kwv mus rau thiab los ntawm JSON txoj hlua ces txoj kev thib peb yog qhov tsim nyog tshaj rau koj.
Kuj Paub, GSON puas siv Jackson?
Cov Gson ntaus hauv gson yog zoo li ObjectMapper hauv Jackson . Ib qhov sib txawv kuv pom ntawm serializing Java khoom rau JSON hlua yog uas los ntawm lub neej ntawd Jackson sau cov khoom uas nws tus nqi yog null. Gson yog tsuas yog qhov opposite. Nyob ntawd yog hloov mus hloov lub Jackson default raws li qhia nyob rau hauv cov cai.
JSON thiab GSON yog dab tsi?
Gson yog lub tsev qiv ntawv Java uas tuaj yeem siv los hloov Java Objects rau hauv lawv JSON sawv cev. Nws kuj tseem siv tau los hloov a JSON txoj hlua mus rau qhov sib npaug Java khoom.
