使用了eclipse编了一个小程序放在D:\JavaProject\JOB下,记录下比较重要的代码段:

String encoding="utf-8";            File file=new File(filePath);            if(file.isFile()&&file.exists()){                InputStreamReader read=new InputStreamReader(                        new FileInputStream(file),encoding);                BufferedReader buffread=new BufferedReader(read);//txt文件写入
String[] split=lineTxt.split(", ");//字符流的分割
BigDecimal db0 = new BigDecimal(lineArray[row][0]);                doubleArray[row][0]=Double.valueOf(db0.toPlainString());//对1.1e1之类的数值转为double型或floatprivate static void OutPutToFile(StringBuffer stringbuffer,String fn){        File file = new File("output_"+fn+".txt");        try {            if (file.exists()) file.delete();            BufferedWriter bw = new BufferedWriter(new FileWriter(file));            bw.write(stringbuffer.toString());            System.out.println("FILE DONE:"+"output_"+fn+".txt");            bw.flush();            bw.close();        }catch (IOException e) {            e.printStackTrace();        }//输入txt文件中  StringBuffer out = new StringBuffer(); OutPutToFile(out,fileName);
try { Thread.sleep ( 1000 ) ; } catch (InterruptedException ie){System.out.println("。。。。。。");} //暂停1000ms

eclipse生成console运行的exe文件:
Help>Install new Software…>FatJar - http://kurucz-grafika.de/fatjar
然后使用exe4j(E:\Program Files (x86)\exe4j)来生成exe

php:

D:\PHPProj下,安装了tomcat,httpd,php,mysql(E:\Program Files (x86)\MySQL),已经配置了httpd 的虚拟目录,VirtualHost

#设置虚拟目录,指向D:\PHPProj\PHPWeb#D:\PHPProj\httpd-2.2.25-win32-x86\conf\httpd.conf<IfModule dir_module>    DirectoryIndex index.html Index.php    Alias /mainWeb "D:\PHPProj\PHPWeb"    <Directory "D:\PHPProj\PHPWeb">    AllowOverride  None    Options Indexes FollowSymLinks    Order allow,deny    Allow from all    </Directory></IfModule>DocumentRoot "D:\PHPProj\PHPWeb"
#test:Spider#D:\PHPProj\httpd-2.2.25-win32-x86\conf\extra\httpd-vhosts.conf<VirtualHost 127.0.0.1:80>    DocumentRoot "D:\PHPProj\PHPWeb\BAIDUSpider"    ServerName Spider    ErrorLog "logs/Spider-error.log"    CustomLog "logs/Spider-access.log" common</VirtualHost>

若Apache服务器软件不想用了,想要卸载,需要先卸载apache服务(切记,若直接删除安装路径的文件夹,会有残余文件在电脑,可能会造成不必要的麻烦)
在CMD命令窗口,输入如下(建议先停止服务再删除):
sc delete apache
apache是Apache服务器的服务名
