i tried using @modelattribute
model.addattribute("custid",customer.getcustid()); model.addattribute("name", customer.getname()); model.addattribute("age", customer.getage()); but not seem work.
model class
package com.projects.data; import javax.persistence.column; import javax.persistence.entity; import javax.persistence.id; import javax.persistence.table; @entity @table(name="customer") public class customer { @id @column(name="cust_id") int custid; @column(name="name") string name; @column(name="age") int age; public customer(int custid,string name,int age) { this.custid=custid; this.name=name; this.age=age; } //getter , setter methods public customer() { // todo auto-generated constructor stub } public int getcustid() { return custid; } public void setcustid(int custid) { this.custid = custid; } public string getname() { return name; } public void setname(string name) { this.name = name; } public int getage() { return age; } public void setage(int age) { this.age = age; } }
remove custform. ${custform.age},${custform.name} , ${custform.custid} in jsp , keep yout model.addattribute in controller. should able access age customer using ${age} in jsp.
controller:
@requestmapping(value = "/customer", method = requestmethod.post) public string addcustomer(@modelattribute("customer") customer customer,model model) { service.addcustomer(customer); model.addattribute("custid",customer.getcustid()); model.addattribute("name", customer.getname()); model.addattribute("age", customer.getage()); return "customer/customer"; } jsp:
<%@ page language="java" contenttype="text/html; charset=iso-8859-1" pageencoding="iso-8859-1"%> <!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=iso-8859-1"> <title>submitted information</title> </head> <body> <h2>submitted information</h2> <table> <tr> <td>customer id</td> <td>${custid}</td> </tr> <tr> <td>name</td> <td>${name}</td> </tr> <tr> <td>age</td> <td>${age}</td> </tr> </table> </body> </html> or
simply model.addattribute("custform",customer); in controller , leave else is.
controller
@requestmapping(value = "/customer", method = requestmethod.post) public string addcustomer(@modelattribute("customer") customer customer,model model) { service.addcustomer(customer); model.addattribute("custform",customer); return "customer/customer"; } jsp keep same in question.
