大家跟着做就可以了,这个代码还可以在修改让他传递个文件名称,生成文件,按照传递的参数实现文件名称,大家自己修改下

toHtml.java(不用修改,直接用)
package com.jetsum.mystatic;
import
java.io.ByteArrayOutputStream;

public class toHtml

//url是要生成htm的jsp页面
String

System.out.println("request.getRealPath"+request.getRealPath(""));
name
= request.getRealPath("") + "/index.htm"; /*生成htm页 位置在%服务器的根目录%/工程名/index.htm
例如:d:/tomcat5.0/webapp/studyteach/index.htm
,注意这里是在根目录生成,你可以生成后放到你想放的文件夹里,保证其它东西如图片的路径正确 这里就写成name = request.getRealPath("")
+ "/kszx/kszx.htm"; */
RequestDispatcher rd =
sc.getRequestDispatcher(url);
final ByteArrayOutputStream os = new
ByteArrayOutputStream();
final ServletOutputStream stream = new
ServletOutputStream()
{
public void write(byte[] data, int offset, int
length) {
os.write(data, offset, length);
}
public void write(int
b) throws IOException {
os.write(b);
}
};
final PrintWriter pw =
new PrintWriter(new OutputStreamWriter(os));
HttpServletResponse rep =
new HttpServletResponseWrapper(response)
{
public ServletOutputStream

return stream;
}
public PrintWriter getWriter()

}
};
rd.include(request,
rep);
pw.flush();
FileOutputStream fos = new FileOutputStream(name); //
把jsp输出的内容写到xxx.htm
os.writeTo(fos);
fos.close();
PrintWriter out =
response.getWriter();
out.print("<p align=center><font size=3
color=red>首页已经成功生成!</font></p>");
}
}
web.xml
中添加
<servlet>
<servlet-name>tohtm</servlet-name>
<servlet-class>com.jetsum.mystatic.toHtml</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>tohtm</servlet-name>
<url-pattern>/web/tohtm</url-pattern>
</servlet-mapping>
使用方法很简单
mytest.jsp(wwwroot下)
<a
href="web/tohtm?urls=/kszx/kszx.jsp">生成静态页</a>
kszx.jsp为要生成htm的动态页
如果不在wwwroot下,在wwwroot/pp下
就要写成
<a
href="../web/tohtm?urls=/kszx/kszx.jsp">生成静态页</a>
