[注意事项&车轮]java源代码 产生局部javadoc api档

随着Eclipse书写java码时间，有时候，因为我们不知道java函数返回。通过鼠标移动到java该功能，假设它javadoc相关内容将被显示。

但是，并非所有java代码javadoc；连装javadoc。于eclipse假设没有设置。使用。

我在win7下安装的是javase的jdk。发现eclipse中默认的javadoc路径是http://download.oracle.com/javase/7/docs/api/，显然这是一个在线资源。问题是网络总是不稳定的，有时候看不到相应的文档内容。

so，what should we do？and what can we do？！

一个显而易见的解决方法是下载javadoc并在本地安装。然后在eclipse中改动javadoc的路径。可是，为什么要下载javadoc？不是有一个命令也叫javadoc的么？不能用么？在java安装路径下能够找到一个叫src.zip的压缩包，里面是java的源代码，并且有凝视，应该能够生成javadoc的。到oracle官方上看了一下。发现javase版本号的jdk就是不带文档的，而javaee版本号的jdk却带文档。好吧，反正我对oracle没有什么好感。对此我仅仅能呵呵。

怎样手动生成本地javadoc api文档？对于jdk中的java源代码，由于包括太多的包，因此须要统计全部使用到的包。也就是“当前路径下包括java文件的全部目录”。

ok。由于google不能用。百度出来的结果基本上是没參考价值，唯一实用的一个是分析swf源代码的样例，够了。通过获取全部包的路径并存储在一个叫package.txt的文件里。并存储在java源代码解压后的路径src下，然后执行cmd。cd到src路径，输入javadoc javadoc -d api @package.txt命令，静候5分钟，文档就会生成完成！

然后我们也能够通过chrome打开。比方JComponent.html页面：

附：用来获取java源代码中全部包括java文件的文件夹的代码：

package util;
import java.io.File;
import java.util.Vector;
public class SniffDir {
	private String srcDir;
	private Vector<String> vs;
	public SniffDir(){
		srcDir="D:/workspace/src";
		vs=new Vector<String>();
	}
	/**
	 * Sniff函数， 事实上就是一个DFS，深度优先搜索
	 * 用来获取src文件夹下的满足“当前路径下存在.java文件”这一条件的全部文件夹
	 * @param file
	 */
	public void Sniff(File file) {
		//File file=new File(curDir);
		File[] files=file.listFiles();
		int len=files.length;
		boolean ok=false;//表示当前文件夹下是否有java文件，ok=true表示有而且记录过了。
		for(int i=0; i<len; i++){
			//System.out.println(files[i].toString());
			if(files[i].isDirectory()){
				Sniff(files[i]);
			}else if(files[i].isFile() && !ok){//files[i]为文件（肯定是java文件）。而且还没有把当前路径放入向量vs中
				ok=true;
				vs.addElement(file.toString().substring(srcDir.length()+1));
				//System.out.println(files[i].toString());
			}
		}
	}
	String sb=null;
	public void Print(){
		int len=vs.size();
		for(int i=0; i<len; i++){
			sb=vs.get(i);
			sb=sb.replace(\'\\\', \'.\');
			System.out.println(sb);
		}
	}
	public static void main(String[] args){
		SniffDir sd=new SniffDir();
		sd.Sniff(new File(sd.srcDir));
		sd.Print();
	}
}

获取的结果（存储在package.txt中并放到src文件夹下就可以）：
