Servlet | 访问不同格式文件（PDF、doc）

核心代码

//设置响应内容类型为PDF类型
response.setContentType("application/pdf");
request.getRequestDispatcher("/WEB-INF/搜索框架.pdf").forward(request,response);

示例：

 import javax.servlet.ServletException;
 import javax.servlet.ServletOutputStream;
 import javax.servlet.annotation.WebServlet;
 import javax.servlet.http.HttpServlet;
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;

 @WebServlet(value="/getFile")
 public class FilePage extends HttpServlet{

     @Override
     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
         processRequest(req, resp);
     }

     @Override
     protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
         processRequest(req, resp);
     }

     protected void processRequest(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException{

         //设置响应内容类型为PDF类型
         response.setContentType("application/pdf");
         request.getRequestDispatcher("/WEB-INF/搜索框架.pdf").forward(request,response);

     }

 }
