在Eclipse中查看Java類庫的源代碼，可以通過Ctrl+鼠標(biāo)左鍵的方式來完成；在下載JDK并安裝的時(shí)候，會(huì)有一個(gè)src.zip文件，此文件就是Java類庫的源碼。但是有時(shí)候，會(huì)出現(xiàn)源碼未找到的問題，此時(shí)可以通過對(duì)其設(shè)置來解決。

以JDK1.8為例，查看一下src.zip文件
如果發(fā)現(xiàn)找不到源代碼，則進(jìn)行設(shè)置
點(diǎn)擊Attach Source按鈕，彈出視圖，把JDK下的src.zip文件傳入點(diǎn)擊OK即可
此時(shí)按住Ctrl+鼠標(biāo)左鍵指向Java類庫當(dāng)中的類，就可以查看類的源代碼
以O(shè)bject類為例演示
在初次使用java時(shí)，往往我們對(duì)最基本的java類會(huì)忽略對(duì)其內(nèi)部基本的實(shí)現(xiàn)的了解，也往往不屑于了解其內(nèi)部實(shí)現(xiàn)機(jī)制，以為它們本來就是這樣子。而其實(shí)貫穿java的整個(gè)過程，所有上層的使用，都是源于對(duì)底層的擴(kuò)展，所以要真正去了解這門語言，就必須得從其底層開始認(rèn)真去了解它。而要深入了解，就需要更多去關(guān)注其內(nèi)部的實(shí)現(xiàn)是怎樣子的。
在使用IDE的過程中，我們經(jīng)常會(huì)需要能在IDE中就可以便捷的去查看java的源碼，但若沒有做相關(guān)設(shè)置，一般在IDE是查看不了java源碼的，此次提供在eclipse中設(shè)置查看java源碼的方式。
設(shè)置步驟如下:
1.點(diǎn) “window”- "Preferences" - "Java" - "Installed JRES"
2.此時(shí)"Installed JRES"右邊是列表窗格，列出了系統(tǒng)中的 JRE 環(huán)境，選擇你的JRE，然后點(diǎn)邊上的 "Edit..."， 會(huì)出現(xiàn)一個(gè)窗口(Edit JRE)
3.選中rt.jar文件的這一項(xiàng)：“c:\program files\java\jre_1.8\lib\rt.jar”?
點(diǎn) 左邊的“+” 號(hào)展開它，
4.展開后，可以看到“Source Attachment:(none)”，點(diǎn)這一項(xiàng)，點(diǎn)右邊的按鈕“Source Attachment...”, 選擇你的JDK目錄下的 “src.zip”文件(該文件在JDK安裝目錄的根目錄下)
5.一路點(diǎn)"ok"，設(shè)置完成
設(shè)置完成后，按住ctrl鍵再用鼠標(biāo)單擊某一個(gè)jdk方法名或類名，便能看到該方法的源代碼了。此外按F3也能實(shí)現(xiàn)。
PS：rt.jar包含了jdk的基礎(chǔ)類庫，也就是你在java
doc里面看到的所有的類的class文件；src.zip文件里面放著的正是基本類所對(duì)應(yīng)的源文件（即*.java格式的文件）；同理，我們可以去網(wǎng)上下載各個(gè)JAVA開源框架所對(duì)應(yīng)的源代碼包，比如spring-src.zip，然后再按照上面的設(shè)置步驟設(shè)置，就可以查看到對(duì)應(yīng)的JAVA框架源代碼了。
