java如何打包

建議使用ANT打包工具，下載地址:

此工具用java編寫，跨平台，能實現很多功能：編譯、打包、運行、文件操作、數據庫操作、自定義任務等。

主要使用方法：在工程目錄下編寫build.xml配置文件，然後運行ant即可：

#ant

或

#java -jar ant.jar

下面給你提供一個例子，是jakarta-oro-2.0.8的包的build.xml

?xml version=”1.0″?

build.xml文件的編寫可參見ant發行版中的使用文檔

你也可以自己編寫腳本打包，使用jdk發行版中的jar命令，例如：

#jar cmf myManifestFile myFile.jar *.class

注意還需要自己編寫MANIFEST.MF文件配置包屬性。具體可以參見javadoc

當然還可以使用集成開發環境提供的打包工具，如JBuilder提供打包工具，但這樣程序的移植性不強，建議不要使用，就使用ant比較好。

如何把java程序打包成exe

將java源碼打包成exe的步驟如下：1、最簡單直接的方法，選擇想打包的程序，右鍵export；2、選擇Java選項，再選擇RunnableJARfile選項，點擊next按鈕；3、選擇程序的主類，還有Main函數的類和輸入要導出的位置，點擊finish；4、在電腦上，設置好Jar文件的打開方式（別默認用解壓縮的工具打開就行），雙擊即可運行。

Java項目寫完後怎麼怎麼打包?

Java項目的打包成jar文件：

eclipse 中選擇要發布的工程右鍵單擊，選擇export

然後在列表中選擇jar（不一定馬上看到，但是可以找到的）

確定後下一步，選擇你要發布的類，反正你要用的到的類全部選擇進去包括圖片或者音樂（音樂和圖片的引用方式有關係，另當別論），然後取個名稱，選擇路徑

再下一步兩次，然後選擇main-class，就是你運行程序時運行的哪個類，選擇後單擊finish，jar文件應該打包成功了，雙擊可以直接運行。

如何將java代碼打包成jar包

方法：

1、啟動eclipse；

2、在eclipse中建立好工程與類並寫好代碼；

3、點擊“File-Export”；

4、在彈擊的界面中選擇“Java-JAR file”，再點擊“Next”；

5、選擇要打包的文件，再點擊“Browse”；

6、在彈出的界面中選擇好打包後的文件的存放路徑，再輸入文件名，最後點擊“保存”；

7、點擊“Finish”；

8、打包成功。
