我在这里有一个输入字段，患者可以在这里搜索医生，并获取医生的所有详细信息，例如他的姓名，费用，经验，专业知识，学位等。因此，我在按钮上具有onclick功能，它会触发使用XMLHttpRequest（）的函数。它从Servlet获取请求，并在jsp页面中显示数据，而无需重新加载它。
protected void doGet(HttpServletRequest request,HttpServletResponse response) throws servletexception,IOException {
Connection connection = null;
PreparedStatement ps,ps2 = null;
ResultSet rs,rs2 = null;
PrintWriter out=response.getWriter();
HttpSession session=request.getSession(false);
String name=request.getParameter("val");
String sql ="select fName,lName,username,exp,fees,user_img from users where fName='"+name+"'";
String sql2="select login_type from users where fName='"+name+"'";
String login_type="";
if(name==null||name.trim().equals(""))
out.print("<p>Please enter name!<p>");
else {
try{
connection = DBConnection.createConnection();
ps=connection.prepareStatement(sql);
ps2=connection.prepareStatement(sql2);
rs = ps.executeQuery();
rs2 = ps2.executeQuery();
while(rs2.next())
login_type=rs2.getString(1);
if(login_type.equals("D")) {
if(!rs.isBeforeFirst())
out.println("<p>No Record Found! <p>");
else {
while(rs.next()) {
response.setContentType("image/jpeg");
out.print("<img src="+session.getAttribute("patientSearchImage")+rs.getString("user_img")+"</img>");
out.print("<table border='1' cellpadding='2' width='100%'>");
out.print("<tr><th>First Name</th><th>Last Name</th><th>Username</th> "+
"<th>Experience</th><th>Fees</th></tr>");
out.print("<tr><td>"+rs.getString("fName")+"</td><td>"+rs.getString("lName")+"</td>"+
"<td>"+rs.getString("username")+"</td><td>"+rs.getString("exp")+"</td><td>"+rs.getString("fees"));
}
out.print("</table>");
}
connection.close();
}else {
out.println("<p>No Record Found! <p>");
}
} catch (Exception e) {
e.printstacktrace();
}
}
}
}
现在，我希望每当患者寻找特定的医生时，他也将获得适当的带有图像样式的细节。我也正在检索医生的图像，但无法显示。如果您除了我正在此处执行的其他想法之外，请随时告诉我。我对所有事物都开放。
