jersey实现文件下载示例

项目名称：jersey,路径前缀：jersey

只通过一个类即可实现该示例：

<span style="font-size:14px;">package com.medivh.control;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

import org.springframework.stereotype.Component;
@Component
@Path("/down")
public class DownService
{
	    @GET
	    @Path("/self")
	    @Produces(MediaType.APPLICATION_OCTET_STREAM)//返回方式为流
	    public byte[] getStudentJl( @Context HttpServletRequest request,@Context HttpServletResponse response) 
	    {
				FileInputStream fis = null;
				try
				{
					fis = new FileInputStream(new File("d:\\html.pdf"));
					byte[] b = new byte[fis.available()];
					fis.read(b);
					response.setHeader("Content-Disposition","attachment;filename=report.pdf");//为文件命名
					response.addHeader("content-type","application/pdf");
					return b;
				}
				catch (FileNotFoundException e) 
				{
					e.printStackTrace();
					return null;
				} 
				catch (IOException e) 
				{
					e.printStackTrace();
					return null;
				}
	    }
}
</span>

web测试服务器为tomcat端口80；
浏览器输入url:http://localhost/jersey/jersey/down/self  即可完成下载。
