FatJar方式：

在Eclipse下生成jar包分很多種情況。最簡單的情況是沒有用到第三方j(luò)ar包，那么直接Export就可以生成jar包。但是如果用到了第三方j(luò)ar包，那么就比較繁瑣了，很不方便。FatJar可以解決這個(gè)問題，使用FatJar，即使包含了很多第三方j(luò)ar包，也可以很方便的生成jar包。

安裝方法：

1. eclipse在線更新方法：help > Install New Sofware > Add...

name：FatJar

URL：http://kurucz-grafika.de/fatjar

2. eclipse插件安裝方法：

解壓后，將解壓出的plugins中的文件復(fù)制到eclipse中的plugins目錄下

然后重啟eclipse，避免Fat Jar被認(rèn)不出來，在eclipse啟動(dòng)時(shí)使用-clean參數(shù)

Ant編譯方式：

使用Ant打包是比較方便的，我們可以在項(xiàng)目根目錄下建立一個(gè)名為build.xml的xml文件，然后在xml文件里面定義我們的打包任務(wù)，如下：

打jar 包時(shí)文件內(nèi)容：
