jsp动态生成静态页面

 

研究了一下动态生成静态页面 废话不多说了 直接上代码

 

 

java代码

package com.jeedroid.makehtml;  

import java.io.*;  

import java.net.malformedurlexception;  

import java.net.url;  

import java.net.urlconnection;  

import java.net.urlencoder;  

public class makehtml  

{  

      

public static void makehtml(string url)  

{  

        try {  

            //读取要访问的文件的内容  

            url _url=new url(url);  

            urlconnection conn=_url.openconnection();  

            inputstream inputstream=conn.getinputstream();  

            bufferedreader buffer=new bufferedreader(new inputstreamreader(inputstream));  

            stringbuilder stringbuilder=new stringbuilder();  

            string line=null;  

            while((line=buffer.readline())!=null)  

            {  

                stringbuilder.append(line);  

            }  

            string filecontent=stringbuilder.tostring();  

            inputstream.close();  

            string htmlfilename=generatefilename(url);  

            file htmlfile=new file("dhtml/",htmlfilename);  

            if(!htmlfile.exists())  

            {  

                htmlfile.createnewfile();  

            //把filecontent写入到html文件中  

                filewriter filewriter=new filewriter(htmlfile,true);  

                bufferedwriter bufferedwriter=new bufferedwriter(filewriter);  

                bufferedwriter.write(filecontent);  

                bufferedwriter.close();  

                filewriter.close();  

            }  

        } catch (malformedurlexception e) {  

            // todo auto-generated catch block  

            e.printstacktrace();  

        } catch (ioexception e) {  

            // todo auto-generated catch block  

            e.printstacktrace();  

        }  

}  

 

//generate html filename according to request url   

public static string generatefilename(string url)  

{  

    string prefilename=url.substring(url.lastindexof("/"));  

    //需要把请求参数中的"?"转换一下  否则文件名不能出现问号  

        string filename=prefilename.replace("?", urlencoder.encode("?"));  

        return filename.replace(".", "_")+".html";  

}  

 

}

package com.jeedroid.makehtml;

import java.io.*;

import java.net.malformedurlexception;

import java.net.url;

import java.net.urlconnection;

import java.net.urlencoder;

public class makehtml

{

      

public static void makehtml(string url)

{

              try {

                     //读取要访问的文件的内容

                     url _url=new url(url);

                            htmlfile.createnewfile();

                     //把filecontent写入到html文件中

                            filewriter filewriter=new filewriter(htmlfile,true);

                            bufferedwriter bufferedwriter=new bufferedwriter(filewriter);

                            bufferedwriter.write(filecontent);

                            bufferedwriter.close();

                            filewriter.close();

                     }

              } catch (malformedurlexception e) {

                     // todo auto-generated catch block

                     e.printstacktrace();

              } catch (ioexception e) {

                     // todo auto-generated catch block

                     e.printstacktrace();

              }

}

 

//generate html filename according to request url

public static string generatefilename(string url)

{

       string prefilename=url.substring(url.lastindexof("/"));

       //需要把请求参数中的"?"转换一下  否则文件名不能出现问号

              string filename=prefilename.replace("?", urlencoder.encode("?"));

              return filename.replace(".", "_")+".html";

}

 

}

 然后用junit做了下测试

 

 

java代码 

package com.jeedroid.makehtml;  

 

import static org.junit.assert.*;  

 

import org.junit.test;  

 

public class makehtmltest  

{  

 

    @test 

    public void testmakehtml()  

    {  

        makehtml.makehtml("https://localhost:8080/dynamictohtml/index.jsp");  

    }  

 

} 

 

package com.jeedroid.makehtml;

 

import static org.junit.assert.*;

 

import org.junit.test;

 

public class makehtmltest

{

 

       @test

       public void testmakehtml()

       {

              makehtml.makehtml("https://localhost:8080/dynamictohtml/index.jsp");

       }

 

}

 还不错 直接生成了静态页面 访问的时候只要用urlrewriter把对index.jsp的请求导向servlet，然后调用上面的javabean，转向html页面就行了 只要url一样就直接显示那个html 哈哈
