我写的一个servlet
运行时抛出的是input Error。那应该是被IOException接收到了，但不知道是错在哪？？？？
package DengRu;
import java.io.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;public class DengRuServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
try{
String zhanghao=request.getParameter("zhanghao");
String mima=request.getParameter("mima");
FileReader file=new FileReader("zhanghao.txt");
BufferedReader fileread=new BufferedReader(file);
String mima1=fileread.readLine();
String zhanghao1=fileread.readLine();
file.close();
fileread.close();
response.setContentType("text/html;charset=utf-8");
PrintWriter out=response.getWriter();
if(zhanghao.equals(zhanghao1)&&mima.equals(mima1)){
//response.sendRedirect("liuyanban.html");
out.println("</html><body>");
out.println(zhanghao+mima);
out.println("</body></html>");
}else{
//response.sendRedirect("denglujiemian.html");
out.println("</html><body>");
out.println("登录失败");
out.println("</body></html>");
}
}catch(IOException e){
log("input Error");
}catch(Exception e){
log("qi ta cuo wu");
}
}
}
