pdf字节流在jsp上怎么显示？

[ljm19891118]

把pdf文件用字节流的方式存入了数据库，在jsp上提供显示或者下载链接，不知道怎么弄了，百度了下，用下面方式，显示pdf，但是我显示的全部是字节流乱码，麻烦帮忙看看

<%@ page contentType="text/html; charset=UTF-8" session="true" import="com.setting.action.FinancePdf,java.sql.Blob"%>
<%@ page import="java.io.OutputStream,java.sql.Blob" %>
<%
try{
	
	byte [] buffer =  FinancePdf.blobToBytes((Blob)request.getAttribute("Pdf"));
        //获取字节流，将blob转化为byte
	response.setContentType("application/pdf;charset=UTF-8"); 
	response.setHeader("Content-Disposition", "attachment; filename=test.pdf" );
	OutputStream outStream = response.getOutputStream();
	outStream.write(buffer, 0, buffer.length);
	outStream.flush();
	outStream.close();
	outStream=null;
	response.flushBuffer();
	out.clear();
	out = pageContext.pushBody();
}
catch(IllegalStateException e)
{
	System.out.println(e.getMessage());
	e.printStackTrace();
}%>

看看你存入数据库的编码格式跟你读出来展示的编码是否一致

编码都是UTF-8，应该没问题。
