在Eclipse中查看Java类库的源代码，可以通过Ctrl+鼠标左键的方式来完成；在下载JDK并安装的时候，会有一个src.zip文件，此文件就是Java类库的源码。但是有时候，会出现源码未找到的问题，此时可以通过对其设置来解决。

以JDK1.8为例，查看一下src.zip文件
如果发现找不到源代码，则进行设置
点击Attach Source按钮，弹出视图，把JDK下的src.zip文件传入点击OK即可
此时按住Ctrl+鼠标左键指向Java类库当中的类，就可以查看类的源代码
以Object类为例演示
在初次使用java时，往往我们对最基本的java类会忽略对其内部基本的实现的了解，也往往不屑于了解其内部实现机制，以为它们本来就是这样子。而其实贯穿java的整个过程，所有上层的使用，都是源于对底层的扩展，所以要真正去了解这门语言，就必须得从其底层开始认真去了解它。而要深入了解，就需要更多去关注其内部的实现是怎样子的。
在使用IDE的过程中，我们经常会需要能在IDE中就可以便捷的去查看java的源码，但若没有做相关设置，一般在IDE是查看不了java源码的，此次提供在eclipse中设置查看java源码的方式。
设置步骤如下:
1.点 “window”- "Preferences" - "Java" - "Installed JRES"
2.此时"Installed JRES"右边是列表窗格，列出了系统中的 JRE 环境，选择你的JRE，然后点边上的 "Edit..."， 会出现一个窗口(Edit JRE)
3.选中rt.jar文件的这一项：“c:\program files\java\jre_1.8\lib\rt.jar”
点 左边的“+” 号展开它，
4.展开后，可以看到“Source Attachment:(none)”，点这一项，点右边的按钮“Source Attachment...”, 选择你的JDK目录下的 “src.zip”文件(该文件在JDK安装目录的根目录下)
5.一路点"ok"，设置完成
设置完成后，按住ctrl键再用鼠标单击某一个jdk方法名或类名，便能看到该方法的源代码了。此外按F3也能实现。
PS：rt.jar包含了jdk的基础类库，也就是你在java
doc里面看到的所有的类的class文件；src.zip文件里面放着的正是基本类所对应的源文件（即*.java格式的文件）；同理，我们可以去网上下载各个JAVA开源框架所对应的源代码包，比如spring-src.zip，然后再按照上面的设置步骤设置，就可以查看到对应的JAVA框架源代码了。
