Integrating Struts, Spring and Hibernate in a web application

[Nilesh Sanyal]

I want to integrate Struts 1.3 with Spring 3.2 and Hibernate 4.0 in a Simple user login application. I want

to use MySQL as the database. I am using Eclipse Mars as the IDE for the development.
I already integrated Struts with Spring, it is working well, but I was unable to integrate Hibernate in the

project, please help.
Table user will be used for the database named users is as follows...

Field              Type            Null    Key   Default
---------------------------------------------------------
username   varchar(30)    yes      no   null
password    varchar(40)    yes      no    null
userid         varchar(4)      no       PRI null

Data stored in that table is as follows...

username     password   userid
------------------------------------
admin           admin123     1


Project structure of the application
------------------------------------------


LoginAction.java
-------------------

package struts.helloworld.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import struts.helloworld.business.BusinessDelegate;
import struts.helloworld.form.LoginForm;

public class LoginAction extends Action{
	
	private BusinessDelegate businessDelegate;
	
	public BusinessDelegate getBusinessDeletage() {
		return businessDelegate;
	}

	public void setBusinessDelegate(BusinessDelegate businessDeletage) {
		this.businessDelegate = businessDeletage;
	}

	
	
	public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest 

request,HttpServletResponse response) throws Exception{
		String target=null;
		LoginForm loginForm=(LoginForm)form;

		target=businessDelegate.validateUser(loginForm.getUserName(), 

loginForm.getPassword());
		request.setAttribute("message", loginForm.getPassword());
		return mapping.findForward(target);
	}
}

BusinessDelegate.java
--------------------------

package struts.helloworld.business;

public class BusinessDelegate {
	public String validateUser(String userName, String password) {
		if(userName.equals("admin") && password.equals("admin123")) {
			return "success";
		}
		
		return "failure";
	}

}

LoginForm.java
------------------

package struts.helloworld.form;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

public class LoginForm extends ActionForm{
	
	private static final long serialVersionUID = 4784666035517885126L;
	private String userName;
	private String password;
	
	public ActionErrors validate(ActionMapping mapping,HttpServletRequest request){
		ActionErrors actionErrors=new ActionErrors();
		
		if(userName==null || userName.trim().equals("")){
			actionErrors.add("userName",new ActionMessage("error.username"));
		}
		
			if(password==null || password.trim().equals("")){
				actionErrors.add("password",new ActionMessage

("error.password"));
			}
		
		
		return actionErrors;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;

If you can at all help it, do not use Struts 1.x.  See this article for why.

I was unable to integrate Hibernate in the project

What did you try?  What problems did you have?
