Getdown utawa Cara ngatur nganyari aplikasi java

Metafiles

Getdown nggunakake rong metafiles: getdown.txt lan digest.txt . Sampeyan nggawe file getdown.txt dhewe (bakal ana katrangan ing ngisor iki), lan program kita bakal nggawe file digest.txt adhedhasar file ing proyek sampeyan.

getdown.txt

File getdown.txt nyimpen kabeh sing dibutuhake Getdown kanggo mbukak lan nganyari aplikasi sampeyan. Saiki kita bakal njlèntrèhaké struktur getdown.txt standar , lan sampeyan bisa maca gambaran lengkap kabeh kemungkinan. Iki kaya getdown.txt standar :

# Alamat URL folder saka ngendi program klien bakal ngundhuh update appbase = http://myapplication.com/myapp/ # File konfigurasi antarmuka pangguna ui.name = Aplikasiku # Kabeh file jar kode aplikasi sampeyan = application.jar # Kelas ing ngendi metode sampeyan dumunung utama (String [] args) kelas = myapplication.MyApplication

appbase ngemot URL ing ngendi aplikasi sampeyan bakal diundhuh lan rong metafiles. Ing kasus kita, path lengkap kanggo aplikasi lan metafiles bakal katon kaya iki:

• http://myapplication.com/myapp/getdown.txt
• http://myapplication.com/myapp/digest.txt
• http://myapplication.com/myapp/application.jar

digest.txt

digest.txt bakal digawe dening com.threerings.getdown.tools.Digester utilitas . Kanggo nindakake iki, download getdown-XYjar . Dadi, ing folder sampeyan saiki sampeyan duwe aplikasi lan siji metafile:

myapp/getdown.txt myapp/application.jar

Iku wektu kanggo nggawe digest.txt , kanggo nindakake iki, ketik ing baris printah:

% java -classpath getdown-XYjar com.threerings.getdown.tools.Digester myapp

ngendi myapp minangka path menyang folder myapp ing ngendi aplikasi sampeyan lan siji metafile saiki ana. Yen sampeyan nindakake kabeh kanthi bener, pesen ing ngisor iki bakal katon ing baris perintah:

Ngasilake file digest 'myapp/digest.txt'...

Lan uga metafile kapindho sing ditunggu-tunggu digest.txt bakal ditambahake menyang folder aplikasi sampeyan . Pandhuan rinci kanggo ngasilake digest.txt bisa ditemokake ing kene

Server

Saiki folder sampeyan ngemot kabeh sing dibutuhake: aplikasi lan rong metafiles. Sampeyan bisa ngunggah menyang server. Aja lali manawa alamat folder kasebut kudu kasebut ing getdown.txt ing lapangan appbase . Lan file internal kudu bisa diakses kanthi alamat folder + jeneng file , i.e. kaya iki:

• http://myapplication.com/myapp/getdown.txt
• http://myapplication.com/myapp/digest.txt
• http://myapplication.com/myapp/application.jar

Priksa karya

Saiki ayo njupuk panggonan klien sing bakal nggunakake aplikasi sampeyan. Pisanan, gawe folder lan selehake getdown-XYjar menyang . Saiki ayo gawe getdown.txt sing mung ngemot siji baris:

appbase = http://myapplication.com/myapp/

Saiki kita nulis printah ing ngisor iki ing baris printah:

% java -jar myapp/getdown-XYjar myapp

Sampeyan kudu mbandhingake file sampeyan karo sing ana ing server yen perlu nganyari lan mbukak aplikasi sampeyan. Iku kabeh! ________________________________________________________________________________________________________ PS Kanggo nggarap baris printah, sampeyan bisa nggunakake file kumpulan, iki sing nggawe digest.bat katon kaya :

java -classpath getdown-1.3.1.jar com.threerings.getdown.tools.Digester %CD%

Lan iki update.bat :

java -jar getdown-1.3.1.jar %CD%
